 Quick Bibliography SeriesBibliographies in the Quick Bibliography Series of the
 National Agricultural Library, are intended primarily for
 current awareness, and as the title of the series implies, are
 not indepth exhaustive bibliographies on any given subject. 
 However, the citations are a substantial resource for recent
 investigations on a given topic.  They also serve the purpose
 of bringing the literature of agriculture to the interested
 user who, in many cases, could not access it by any other
 means.  The bibliographies are derived from computerized on-
 line searches of the AGRICOLA data base.  Timeliness of topic
 and evidence of extensive interest are the selection criteria.
 
 The author/searcher determines the purpose, length, and search
 strategy of the Quick Bibliography.  Information regarding
 these is available upon request from the author/searcher.
 
 Copies of this bibliography may be made or used for
 distribution without prior approval.  The inclusion or
 omission of a particular publication or citation may not be
 construed as endorsement or disapproval.

 Abstract:  Boron isotope ratios (11B/10B) for commercial
 produce ranged from a high of 4.162 +/- 0.003 for cabbage to a
 low of 4.013 +/- 0.008 for whole wheat flour. The observed
 isotope ratios for produce fall within the range reported for
 boron-containing minerals. Cucumbers and flour are 10B
 enriched; bananas, cabbage, celery, grapes, green peppers,
 lettuce, oranges, potatoes, and tomatoes are 11B enriched by
 at least 0.02; apples, broccoli, cantaloupe, and carrots are
 equal to NIST SRM-951 boric acid isotopic standard. Boron
 isotope ratios (11B/10B) were measured for broccoli and
 cabbage grown in a soilless medium, 4.018 +/- 0.016 and 4.032
 +/- 0.003, in a soilless medium with foliar-applied H3 1OBO3,
 1.848 +/- 0.009 and 1.746+/- 0.004, and in a hydroponic
 solution with H3 1OBO3 as the only boron source, 0.126 +/-
 0.012 and 0.098 +/- 0.005.

 Requirements
 
 Abstract:  Knowledge of the micronutrient requirements of
 strawberries is rather scarce. This plant species is
 considered to have low sensitivity to boron deficiency. In our
 work several aspects of B requirements of Fragaria ananassa L.
 cv. Douglas have been studied. Strawberries were grown in an
 automated greenhouse and in aerated nutrient solution with
 (+B) and with (-B) boron supply. The experiment started when
 fresh plants were transferred from the nursery to 4-litres
 pots (5 plants per pot) following the cultivation steps of a
 typical commercial production in Spain. Plant material (shoot
 and root) was sampled every two weeks after a gap of one
 month. Simulaneously, nutrient solutions were analyzed and
 renewed. B concentration in the n utrient solutions of both +B
 and -B increased during the 2-weeks period of culture. This
 increase was initially high but became smaller in successive
 periods. Boron content was higher in +B leaves than in -B
 ones. Nevertheless neither visula symptoms of B deficiency,
 nor reduction in growth in yield were observed in -B plants
 during the 4 months of the experiment. The lower boron
 concentration of young leaves in comparison with older ones
 would suggest a continuous supply of B from the root and a
 weak capacity of redistribution of the microelement via the
 phloem. In conclusion it appears that the large amount of
 boron stored mostly in the root at the beginning of the assay
 would be sufficient to cover the low B requirements of the
 strawberry plant studied.

 Abstract:  Tomato plants (Lycopersicon esculentum Mill.) of
 the F1 hybrid variety Turbo were grown in a NFT system for 22
 days. On days 16 and 20-22 inclusive of the experiment, the
 diurnal variation in nitrate (NO3), potassium (K), and water
 uptake rates were measured. Nitrate and K uptake rates were
 subject to large diurnal variation with maximum uptake rates
 occurring during the day period. Two peaks of diurnal uptake
 rates were identified, one large peak during the day period
 and a second much smaller one during the first 2-4 hours of
 the night. Under the conditions of the experiment, night
 nutrition made up 35 to 40% of the total daily uptake of K and
 NO3. Water uptake rates followed a diurnal oscillation with a
 single peak pattern. Highest rates occurred at the middle of
 the photoperiod and lowest rates were measured at night. Over
 the entire day and night cycle there was no correlation
 between the rates of water and nutrient uptake. This may be of
 importance in the fertilization of hydroponically grown plants
 since in horticultural practice nutrients and water are
 supplied together in quantities large enough to meet plant
 water demand but not nutrient requirements.

 Abstract:  An algorithm was developed to select a economically
 optimum temperature trajectory for greenhouse hydroponic
 lettuce production. Daily air temperature was selected to
 maximize he difference beween crop worth and cost to heat. To
 select an optimum temperature, crop worth was determined for a
 range of possible inside temperatures by projecting crop
 growth forward to harvest using expected values of weather
 variables based on historical weather data. After an optimum
 temperature for the day in question was selected, the status
 of the lettuce crop was updated based upon the selected
 temperature and the day's actual weather data.

 Abstract:  Results of simulations from a computer model
 developed to determine economically optimum day temperature
 for greenhouse hydroponic lettuce production are presented.
 Selected optimum air temperature is a function of many factors
 including available insolation, stage of growth of the crop,
 length of the growing period, lettuce worth, and fuel costs.
 Potential savings due to production at optimum day
 temperatures compared to standard temperatures were estimated
 based on simulation of five years of operation. Potential
 savings vary depending on fuel cost and whether the greenhouse
 is operated such that only plants of the same age are present
 or such that many age groups are present simultaneously.
 Savings varied form 10 to 30% of the heating costs.

 Abstract:  In addition to essential inorganic nutrients,
 plants may need other organic substances as they have grown in
 soil. The capacity of microorganisms to synthesize biotic
 substances in a soil has been for a long time. Of these
 substances, a B-group of vitamins (Thiamine, Nicotinic acid,
 and Pyridoxine) and amino acid (cysteine) were selected as
 good source of nutrition for the plants. Present paper shows
 the effect of the addition of a mixture of these organic
 substances and iron to the nutrient solution on the growth and
 nutrient uptake in cut-flower chrysanthemum in the nutrient
 film technique system. A mixture of these substances added to
 the basal nutrient solution had a marked effect upon the
 growth and uptake of inorganic nutrients in chrysanthemum
 plant. Leaf green color was intensified by the treatment of
 liquid fertilizer containing thiamine, iron, and cysteine. As
 a side effect, these substances gave resistance of plants to
 unfavorable conditions.

 Abstract:  Butterhead lettuce (var. Gloria) were grown in an
 evaporatively cooled glasshouse using the nutrient film
 technique (NFT). During the day all plants received a complete
 nutrient solution (EC 2 dS/m). Treatments were imposed at
 night and included: complete nutrient solution (control); tap
 water (EC 0.19 dS/m); and calcium nitrate solutions containing
 either 100 mg Ca/L (EC 0.80 dS/m), or 200 mg Ca/L (EC 1.45
 dS/m). Tipburn occurred in the control and its incidence was
 reduced by the other treatments. This effect was associated
 with an increase in the concentration of calcium in new
 leaves, except in the water treatment. The night treatments
 did not affect the fresh weight of mature lettuce. Circulation
 of either water or calcium nitrate (100 mg Ca/L) at night may,
 therefore, be a commercially acceptable means of reducing
 tipburn losses in lettuce crops grown using hydroponics.

 Abstract:  Butterhead and cos type lettuce (Lactuca sativa L.)
 .cv. "Bellona" and "Paris cos island" respectively, were grown
 in nutrient film culture, under various electrical
 conductivity levels (1.5-2.0-2.5-3.0-4.0-5.0 mS). Fresh and
 dry weights of shoots and roots were measured for their
 seasonal growth, over a period from October to May, under an
 unheated glasshouse. For both cultivars the overall effect of
 solution conductivity on shoot fresh weight, was minor.
 Increases in conductivity resulted in increased root dry
 weight.

 Abstract:  Hydroponically grown mung bean seedlings were
 inoculated with macroconidia of Fusarium solani f. sp.
 phaseoli to evaluate the effects of temperature (15, 20, 25,
 30, and 35 C) and hydrogen ion concentration (pH 3, 4, 5, 6,
 and 7) on spore attachment to roots of Vigna radiata.
 Macroconidia of F. s. phaseoli attached to second-order roots
 with root hairs in greater numbers than to those without root
 hairs or to roots of other orders. Attachment of macroconidia
 to second-order roots was greatest at 20-30 C and pH 4 but
 decreased by up to two orders of magnitude when the
 temperature of the nutrient solution was increased to 35 C or
 the pH elevated to 7. The binding reaction of macroconidia to
 roots was observed to be reversible when plants inoculated at
 25 C and pH 5 were transferred to nutrient solutions
 maintained at 35 C or pH 7. Plant fresh weights of V. radiata
 decreased with increasing inoculum density when plants were
 inoculated and maintained at 20 or 25 C but not at 30 C.
 Differences in plant fresh weights of V. radiata between
 inoculated and uninoculated plants were greatest at 20 C,
 decreased at 25 C, and were not observed at 30 C. In a
 separate experiment, plant roots were exposed to inoculum for
 24 h at 24 C and pH 4, 5, 6, or 7. The nutrient solutions of
 each treatment were then adjusted to and maintained at pH 6
 for an additional 13 days. Disease was greatest when roots
 were inoculated at pH 4 as compared to pH 5 or 6. Plants
 inoculated at pH 7 were not different from uninoculated
 plants. Differences in disease among plants inoculated at
 different hydrogen ion concentrations are explicable when
 based on the effects of hydrogen ion concentration on the
 attachment of macroconidia to root surfaces. Differences in
 disease among plants inoculated at different temperatures
 between 20 and 30 C are not explicable when based on the
 effects of temperature on spore attachment to roots or on
 growth of the pathogen. We propose that differences in disease
 among plant

 Abstract:  Sweet potato [Ipomoea batatas (L.) Lam.] is among
 eight crops selected by NASA for its Controlled Ecological
 Life Support Systems (CELSS) program. This research evaluated
 sweet potato genotypes for adaptability to hydroponic systems.
 Fourteen sweet potato genotypes were grown hydroponically
 using nutrient film technique (NFT) systems. Four vine
 cuttings from each genotype were spaced at 25 cm and grown for
 120 d using 14 NFT channels (0.15 by 0.15 by 1.2 m) supplied
 with a modified half-Hoagland nutrient solution. Genotypes
 responded differently to growth in NFT. 'Jewel' produced the
 highest mean total storage-root yield of 470 g per plant.
 Individual plant yields ranged from 767 g for 'Centennial' to
 36 g for 'Bunch'. Inverse relationships between foliage weight
 and storage-root yield were obtained with 11 genotypes. Edible
 biomass indices were comparable to those of potato (Solanum
 tuberosum L.) and lettuce (Lactuca sativa L.), and higher than
 those of wheat (Triticum aestivum L.) and soybean [Glycine max
 (L.) Merr.]. Based on their performance, Jewel, 'Carver',
 TU-52, and Centennial sweet potato appear well adapted to
 growing in NFT.

 Abstract:  We have developed a flow-through system (FTS) to
 study the effects of root restriction stress on plants grown
 in hydroponic culture. The system was designed to permit the
 use of varied culture container volumes (from 25 to 1500 cm3)
 and dimensions (2.5 to 10 cm. dia. and 5 to 20 cm h.). The
 modular FTS design is divided into two nutrient delivery
 systems, one for large-volume containers and the other for
 small-volume containers. Each plant was grown in a modified
 Hoagland solution in a separate container. Nutrient solutions
 were aerated and the pH was automatically controlled at 6.0 +/-
  0.2. This report describes the FTS and presents growth data
 for tomato plants (Lycopersicon esculentum Mill., cv. 'Better
 Bush') grown for a 57 day period. Our observations, when
 compared to the findings of a root restriction study made by
 Ruff, et al. 1987 (J. Amer. Soc. Hort. Sci. 112: 763-769),
 indicate that that similar characteristics result for the same
 tomato cultivar grown in either pot culture (soil) or
 hydroponics (FTS). The result of this test of the FTS supports
 the continued use of the system to study various physiological
 and hormonal parameters in relation to root restriction.

 Abstract:  During the 1987-1988 and 1988-89 growing season an
 experiment was conducted in a cold plastic greenhouse of our
 Institute aiming to evaluate five substrates in two vertical
 systems with respect to their suitability for growing
 strawberries. The following substrates were evaluated: a.
 perlite 100%, b. perlite 90% + peat 10%, c. perlite 80% + peat
 20%, d. pumice-stone 80% + peat 20%, e. pumice-stone 80% +
 perlite 20%. They were placed either in polyethylene tubes,
 1.70 m height and 0.15 m diameter in a vartical position, or
 in pots of polystyrene placed one above the other in a column
 1.70 m in height. In both cases, 36 plants of the strawberry
 cultivar Brighton were planted in each column in August. A
 system for recycling the nutrient solution was applied. Yield
 was collected from December until June. About 65% of the yield
 was taken until the end of April. Data obtained indicate that
 strawberries grown on substrate composed of perlite 80% + peat
 20% produced higher yield (250 gr/plant) than those gorwn on
 the other substrates. There was no difference between
 polystyrene pots and polyethylene tubes with respect to yield.

 Abstract:  The development of the hydroponic perlite culture
 system of protected crop production at the West of Scotland
 College has been based, hitherto, or coarse, 'horticultural-
 grade' expanded perlite which has 90% by volume in the range
 1-5 mm. Recent work has compared crop performance of
 glasshouse tomatoes in horticultural-grade perlite with that
 in two Sardinian plaster-grades which have much finer
 particle-size distributions, one with 90% by volume in the
 range 0.6-1.4 mm, the other 90% volume <1 mm. Cumulative
 yields of fruit were similar in each of the three grades of
 perlite to the end of Ausust in 1987 and to the end of
 September in 1988. Hence, although the air-filled porosity of
 the Sardinian plaster-grade perlite was lower than either the
 medium or horticultural-grade material, oxygen availability at
 the root surface did not limit root function.

 Abstract:  Three hydroponic systems, namely rockwool, perlite
 and NFT, are described. Factors affecting growth such as root
 temperature, water quality and aeration are discussed,
 together with management problems including sterilization
 between crops. Current sensitivity about environmental
 pollution is likely to cause some reduction in the use of
 systems that discharge nutrient solutions containing
 appreciable amounts of nitrate-nitrogen to waste.

 Abstract:  A highly specific and sensitive ELISA method was
 developed for the detection and semi-quantitative
 determination of artemisinin and its structurally related
 compounds in crude extracts of Artemisia annua. The antibodies
 were raised in rabbits using a 10-succinyldihydroartemisinin-
 BSA conjugate as immunogen. The peroxide linkage in the
 artemisinin molecule was critical in determining the antibody
 specificity. The working range of the assay was from 0.02 to
 10 ng per assay. The cross-reacting material in crude plant
 extracts was evaluated by chromatographic methods combined
 with the immunoassay method. The distribution of artemisinin
 equivalents in five-week-old A. annua plants cultivated in
 hydroponic conditions was investigated. The highest
 artemisinin equivalent content (1.12% dry wt) was found in the
 leaves of the upper parts of the plant.

 Abstract:  Dihaploid Solanum tuberosum and diploid S.
 microdontum plants were grown in soil and hydroponics under
 glasshouse and growth room conditions. A high light intensity,
 was necessary for flower induction in both species and the
 dihaploid flowered only when grown in hydroponics. Premature
 berry abscission was retarded by tuber removal and prevented
 by the addition of indole acetic acid to the nutrient
 solution. Seeds from prematurely abscised berries germinated
 poorly in soil, but germinated almost as well as those seeds
 from indole acetic acid-treated plants when placed on
 Murashige and Skoog (1962) based culture medium. The hybrid
 plants were intermediate in morphology, compared to the
 parents, possessed heterotic vigour and were male fertile.
 Germinating hybrid seeds on a colchicine-containing medium led
 to poorly growing plants with ploidy chimeras. Hybrid plant
 ploidy levels were doubled by regenerating plants from
 stem/leaf explants on the tuber disc regeneration medium of
 Jarret et al. (1980).

 Abstract:  The morphology and hydraulic conductivity of root
 systems of Gleditsia triacanthos L. var. inermis Willd. (honey
 locust) grown hydroponically in sand and solution cultures
 were compared. Total root system length was similar in the two
 cultures. However, root systems grown in solution had longer
 primary roots, fewer lateral roots and root hairs, and a
 greater distance between the tip of the primary root and the
 junction of the youngest secondary root and the primary root
 than root systems grown in sand. Hydraulic conductivities of
 root systems grown hydroponically for 21 or 35 days in sand or
 solution culture were similar. These findings show that
 different methods of hydroponic culture can affect root
 morphology without altering root resistance to water
 transport.

 Abstract:  It is possible to restrict the vegetative growth of
 early protected tomato crops, growing in the nutrient film
 technique (NFT) water culture, by supplying the nutrient
 solution intermittently instead of continuous flow.
 Intermittent flow regime given up to anthesis of the fourth
 truss, increased early yield but did not increase the final
 total yield. There was a highly significant decrease in root
 fresh weight. Also, a reduction in all intermittent treatment
 of water consumption 22%, was noticed under the intermittent
 flow. The water use efficiency calculated on the basis of
 fresh and dry weights increased under intermittent treatments.

 Abstract:  Sweetpotato [Ipomoea batatas (L.) Lam] is being
 grown with the nutrient film technique as part of the National
 Aeronautics and Space Administration's Controlled Ecological
 Life Support System (CELSS) program for long-termed manned
 space missions. Our objective was to evaluate the effects of
 two levels of photosynthetic photon flux (480 and 960
 micromoles m(-2)s(-1) PPF) and three N/K ratios (1:1.1, 1:2.4,
 and 1:3.6) on yield of sweetpotato when grown using this
 technique. Vine cuttings (15-cm length) of 'Georgia Jet' and
 T1-155 were grown in each treatment for 90 or 120 d,
 respectively, in controlled-environment growth chambers.
 Storage root growth for Georgia Jet and T1-155 increased with
 light intensity, while foliage growth decreased with high K
 levels. The number of storage roots produced by each plant
 increased with intensity only for Georgia Jet but was not
 significantly influenced by higher K levels for either
 cultivar. Light by N/K interactions were not significant. The
 level of PPF exerted a greater effect in enhancing sweetpotato
 storage root yield in nutrient film than did N/K ratio.

 Abstract:  Development of the use of perlite in horticulture
 has been carried out at the West of Scotland College over a
 period of more than ten years. Recent work in collaboration
 with The Perlite Institute, Inc. has led to the development of
 commercially applicable techniques. The outstanding features
 of the system include ease of water management and optimum
 air:water balance, because perlite substrate is initially
 sterile, chemically inert and physically stable. Simple
 irrigation design of one inlet per row of plants makes the
 system suitable for low-technology conditions which exist in
 many parts of the world.

 Abstract:  We describe the mechanical, electronic, hydraulic,
 and structural design of a nonrecirculating hydroponic system.
 The system is particularly suited to studies at very low
 nutrient concentrations, for which on-line concentration
 monitoring methods either do not exist or are costly and
 limited to monitoring relatively few individual plants.
 Solutions are mixed automatically to chosen concentrations,
 which can be set differently for every pump fed from a master
 supply of deionized water and nutrient concentrates. Pumping
 rates can be varied over a 50-fold range, up to 400 liters per
 day, which suffices to maintain a number of large, post-
 seedling plants in rapid growth at (sub)micromolar levels of N
 and P. The outflow of each pump is divided among as many as 12
 separate root chambers. In each chamber one may monitor uptake
 by individual plant roots or segments thereof, by measuring
 nutrient depletion in batch samples of solution. The system is
 constructed from nontoxic materials that do not adsorb
 nutrient ions; no transient shifts of nitrate and phosphate
 concentrations are observable at the submicromolar level.
 Nonrecirculation of solutions limits problems of pH shifts,
 microbial contamination, and cumulative imbalances in
 unmonitored nutrients. We note several disadvantages,
 principally related to high consumption of deionized water and
 solutes. The reciprocating pumps can be constructed
 inexpensively, particularly by the researcher. We also report
 previously unattainable control of passive temperature rise of
 chambers exposed to full sunlight, by use of white epoxy
 paint.

 Abstract:  Water culture experiments are described which
 provide conclusive evidence that Mo uptake by tomato plants is
 markedly enhanced by P deficiency. In a longterm experiment,
 which ran for 11 days, in marked contrast to the uptake of
 other nutrients, a three fold higher Mo uptake rate was
 observed after only four days of withdrawal of P from the
 nutrient medium. In contrast to the gradual increase in pH of
 the nutrient medium of the plants supplied with P, the pH in
 the medium of the -P plants fell. Throughout the growth of
 these plants net H+ efflux could be accounted for by excess
 cation over anion uptake, indicating that organic acid
 extrusion plays no major role in the observed fall in pH.
 Further evidence that Mo uptake is enhanced in P deficient
 tomato plants is provided in short-term nutrient solution
 experiments (1h and 4h) using radioactive molybdenum (99Mo).
 Compared with P sufficient plants, the uptake rates of 99Mo by
 P deficient plants were three to five times higher after 1h
 and nine to twelve times higher after 4h. Resupplying P during
 the uptake periods to deficient plants reduced the uptake rate
 of 99Mo to values similar to those of P sufficient plants. It
 is concluded that the uptake of molybdate occurs via phosphate
 binding/ transporting sites at the plasma membrane of root
 cells. Further support for this conclusion comes from exchange
 experiments with non-labelled molybdenum, which show a much
 larger amount of 99Mo exchangeable from the roots of P
 deficient plants.

 Abstract:  This study was conducted to evaluate the responses
 of potatoes to six K solution concentrations maintained with a
 flow-through nutrient film system. Potato plants were grown
 for 42 days in sloping shallow trays containing a 1 cm layer
 of quartz gravel with a continuous flow of 4 ml min(-1) of
 nutrient solutions having K concentrations of 0.10, 0.55,
 1.59, 3.16, 6.44, 9.77 meq L(-1). Plant leaf area, total and
 tuber dry weights were reduced over 25% at 0.10 meq L(-1) of K
 and over 17% at 9.77 meq L(-1) of K compared to concentrations
 of 0.55, 1.59, 3.16 and 6.44 meq L(-1) of K. Gas exchange
 measurements on leaflets in situ after 39 days of growth
 demonstrated no significant differences among different K
 treatments in CO2 assimilation rate, stomatal conductance,
 intercellular CO2 concentration, and transpiration. Further
 measurements made only on plants grown at 0.10, 1.59, 6.44 meq
 L(-1) of K showed similar responses of CO2 assimilation rate
 to different intercellular CO2 concentrations. This suggested
 that the photosynthetic systems were not affected by different
 K nutrition. The leaves of plants accumulated about 60% less K
 at 0.10 meq L(-1) of K than at higher K concentrations.
 However, Ca and Mg levels in the leaves were higher at 0.10
 meq L(-1) of K than at higher K concentrations. This indicates
 that low K nutrition not only reduced plant growth, but also
 affected nutrient balance between major cations.

 Abstract:  A recirculating resin-buffered hydroponic system
 was developed to control the activities of nutrient ions in
 solution at concentrations similar to those found in soil
 solution. The recirculating hydroponic system was designed to
 supply adequate buffering and timely replenishment of
 nutrients during the course of long-term experiments. Nutrient
 solution was recharged by circulating it through columns of
 ion exchange and chelating resins before its return to plant
 culture vessels. The recirculating resin-buffered system
 consisted of four different types of ion exchange and
 chelating resins housed in separate columns: strong-acid resin
 to buffer Ca, Mg, K and Mn in solution; weak-acid resin to
 buffer pH; partially-neutralized Al on strong-acid resin to
 buffer P in solution; and chelating resin to buffer Zn, Cu,
 Mn, and Ni and to supply Fe to EDDHA in solution. Control of
 nutrients and pH was begun at the time of seed germination.
 The recirculating resin-buffered system was especially
 designed to limit Ni contamination in studies of the
 essentiality of Ni in higher plants. Concentrations of Ni2+ is
 solution were successfully maintained at treatment levels that
 differed by four orders of magnitude, with the lowest level <
 10(-14) M. The exchange resins maintained the supply and
 activities of other nutrients at levels sufficient for the
 growth of plants. Tomato plants (Lycopersicon esculentum
 Mill., cv. Wisconsin 55) were successfully grown for six weeks
 without discarding the nutrient solution in which the plants
 grew. The pH of recirculating nutrient solutions was well
 maintained throughout the study. Guard columns protected the
 primary resin columns from plugging and were replaced during
 the course of this study to restore flow rates of the nutrient
 solutions. Maintenance of flow rates, in conjunction with
 successful reloading of resins with nutrients, assures the
 feasibility of even longer term plant culture experiments.

 Abstract:  Root characteristics of wheat (Triticum aestivum
 L.) genotypes are believed to be important in tolerance to
 drought and flooding, yet neither the extent of differences in
 root size among modern soft red wheat cultivars nor the degree
 of association between root size and drought or flooding
 tolerance is known. This study was conducted to see whether
 genotypes differ in root size, and to see if root size is
 associated with tolerance to flooded soil and to drought
 during early vegetative growth. We found differences in root
 fresh weight (RFW), shoot fresh weight (SFW), number of roots
 longer than 40 cm (NR), longest root length (LRL) and total
 root length (TRL) of 40 winter wheat genotypes grown in
 hydroponic culture for 4 wk. Each of these parameters was
 positively correlated with all others. Twelve genotypes with
 different root sizes selected from these 40 were grown in a
 greenhouse soil experiment for 3 wk, after which soil moisture
 treatments of control, flooding, and drought were imposed for
 a period of 21 d. Flooding did not affect SFW and number of
 tillers (NT), but decreased RFW. Drought drastically decreased
 all three parameters. The genotype X moisture treatment
 interactions for SFW, RFW, and NT were significant. Root and
 shoot growth of these genotypes in hydroponic culture were
 correlated to their root and shoot growth under both control
 and flooded conditions, but not under drought. Thus, it
 appears that the expression of genotypic root growth potential
 may be influenced by the availability of soil moisture, and
 that selection of wheat seedlings for vigorous growth in
 hydroponic culture will select for vigorous early growth in
 soil with adequate or excess moisture, but not under severe
 drought.

 Abstract:  The effects of increased salinity [NaCl + CaCl2] on
 seedling of three tepary and four common bean cultivars/lines,
 of known resistance and susceptibility at germination stage,
 grown for thirty-eight-days in salinized hydroponic and sand
 cultures were assessed at electrical conductivity (EC) of 1.89
 (control), 4.00, 8.00, and 12.00 dS/m of half strength
 Hoagland solution inside a glasshouse at 30/25 +/- 2 degrees C
 day/night temperature. The hydroponic culture screening method
 was more severe than the sand culture method. Common bean
 cultivars/lines expressed genetic variability to salinity
 stress at thirty-eight-days old seedlings. 'Badrieh' was
 tolerant to salinity as the tolerant tepary bean T#1 line
 under sand culture. However, this was not evident under
 hydroponic culture. T#1 showed salinity injury symptoms at EC
 = 4 dS/m, while 'Badrieh' showed no salinity injury symptoms
 at EC = 4 dS/m. These results indicate that the mechanisms
 involved for tolerating salinity in the tepary could be
 different from that involved in common beans. Inverse and
 significant correlations between salinity injury symptoms and
 several root and shoot characters were evident from the data,
 indicating that variation in whole-plant foliar injury
 symptoms to salinity would thus seem to provide the best means
 of initial selection of salinity tolerant genotypes by plant
 breeders.

 Abstract:  Commercial recommendations exist for using short-
 term salt-shocks on tomato (Lycopersicon esculentum Mill.) to
 improve fruit quality. Six experiments were conducted to 1)
 assess the influence of nutrient concentration and short-term
 salt-shocks on fruit quality and yield and 2) identify a
 vegetative predictor of subsequent fruit quality. The first
 objective was addressed in three nutrient film technique (NFT)
 experiments (Expts. 1-3). Four treatments were applied: two
 maintained constant at two baseline concentrations (0.25X and
 1X-commercial level) and two provided salt-shock periods of 30
 min, twice daily. There were no effects of baseline
 concentration or salt-shocks on total number and weight of
 marketable fruit. Fruit quality was better at the 1X baseline
 concentration as observed by higher titratable acidity (Expt.
 2), higher percent dry matter (Expts. 2 and 3), higher soluble
 solids concentration (Expt. 2), and lower pH (Expts. 2 and 3),
 however, weight per marketable fruit was lower (Expt. 2).
 Salt-shocks had little effect on fruit quality, refuting its
 commercial potential. Salt-shocks decreased fruit pH (Expts. 1
 and 3). However, titratable acidity increased at the 0.25X
 level and decreased at the 1X level (Expt. 3). In Expt. 2, but
 not in Expt. 3, citrate concentration in the fifth leaf from
 the apex of young vegetative plants was correlated with
 subsequent fruit quality. Three additional experiments in
 static hydroponics with vegetative plants showed no
 significant differences in leaf citrate levels due to a
 single, short-term salt-shock. Thus, citrate is not a good
 predictor of fruit quality.

 Abstract:  Defruited cucumber (Cucumis sativus L.) plants were
 grown hydroponically for 28 days in containers with 4.5 liters
 of capacity, in which constant solution depths of 1, 5, 50,
 and 170 mm were maintained. The plants grown in the 1- and 5-
 mm-deep solutions grew more slowly than those in the deeper
 solutions. Both root and shoot growth were reduced at the
 shallow depths, but shoot growth was affected more than root
 growth. Thus, the shoot : root ratios were considerably
 smaller in the shallower than in the deeper solutions. The
 root systems in the shallower solutions, initially, were
 relatively more branched than in the deeper solutions. The
 shallow solutions caused the plants to allocate a higher
 proportion of their photosynthetic resources to the root at
 the expense of leaf growth. In the shallow solutions, a
 progressively higher proportion of this root growth became
 exposed above the solution, and, therefore, could not
 contribute to the absorption of water and nutrients. Control
 of solution depth may be a useful tool for controlling the
 vigor of the shoots of cucumber and the data presented may
 explain why growth problems have been experienced with this
 crop, particularly where a very thin film of nutrient is used,
 as in nutrient film technique.

 Abstract:  A hydroponic culture system that enables ready
 production and retrieval of freshly hatched, infective root-
 knot nematode juveniles was developed. Meloidogyne javanica-
 infected tomato plants produced at least 100,000 juveniles per
 day for as long as 3 mo. Juveniles reinfected roots within the
 culture system, which possibly accounts for the extended
 period of production. The hydroponically grown nematodes
 retained characteristic infectivity and host range. This
 culture system is useful when a cohort of uniform-age
 juveniles is required or for analyses in which high numbers of
 nematodes are needed.

 Abstract:  Tillering and growth parameters of perennial
 ryegrass cultivars Wendy (diploid) and Condesa (tetraploid)
 were determined in a glasshouse experiment using hydroponics
 at low (-1.3 MPa) and normal water potential (0 MPa). At -1.3
 MPa, leaf extension rate was reduced by 36%. Final plant
 tiller number was 20% lower at -1.3 MPa because of a 12%
 reduction in the leaf appearance rate in the first weeks after
 the start of the treatments. Site filling, the relative
 increase in tiller number per leaf appearance interval, was
 high (0.61) - but still lower than theoretically possible -
 and was only slightly affected by water potential. Site
 filling was shown to be strictly related to the number of
 inhibited plus unemerged tiller buds. Dry matter production
 was 64% lower at -1.3 MPa. Relative growth rate (RGR) was, on
 average, 17% lower at -1.3 MPa, but the reduction was greater
 just after the treatments started. Also, net assimilation rate
 (NAR) was reduced more by low water potential just after the
 start of the treatments. Specific leaf area (SLA) was 13%
 lower at -1.3 MPa for Wendy, but not significantly reduced for
 Condesa. Contrary to expectations based on the theory of the
 functional balance between root and shoot, leaf weight ratio
 was slightly higher at -1.3 MPa. From comparison of the
 results of this study with published data, it is concluded
 that effects of drought in the field on tillering cannot be
 attributed only to low water potential.

 Abstract:  Substitution of urea for commonly used nitrate
 fertilizers in hydroponic culture of vegetables would not only
 avoid excessive accumulation of nitrate in plants but would
 also reduce the cost of production. This substitution,
 however, might have adverse effects, such as a dramatic
 decrease in solution pH, reduced nutrient uptake and possibly
 urea toxicity per se. Differences in adaptability to urea were
 found among three species of leafy vegetables, Ipomoea
 aquatica Fossk., Lactuca sativa L. and Brassica chinensis L.
 I. aquatica showed the best adaptability, growing normally
 with urea as the sole nitrogen source in spite of the dramatic
 pH decrease in the nutrient solution. It was further found
 that I. aquatica had significantly lower urease activity in
 the roots than the other two species when urea was supplied to
 the solution. Tolerance of low pH and avoidance of urea
 toxicity may be possible mechanisms of I. aquatica's
 adaptability to urea application in hydroponic culture.

 Abstract:  A nutrient delivery system that may have
 applicability for growing plants in microgravity is described.
 The Vacuum-Operated Nutrient Delivery System (VONDS) draws
 nutrient solution across roots that are under a partial vacuum
 at approximately 91 kPa. Bean (Phaseolus vulgaris L. cv. Blue
 Lake 274) plants grown on the VONDS had consistently greater
 leaf area and higher root, stem, leaf, and pod dry weights
 than plants grown under nonvacuum control conditions. This
 study demonstrates the potential applicability of the VONDS
 for growing plants in microgravity for space biology
 experimentation and/or crop production.
