Plant Physiology Laboratory
The
Plant Physiology Laboratory and plant growth facilities
span 2,200 square feet and are located on the 11th
floor of the CNRC. Under the direction of a USDA plant
physiologist, this laboratory is dedicated to understanding
the nutrient transport systems of plants as a means
of improving food crops.
Plant
scientists also assist other CNRC investigators by
growing and "labeling" food plants like peas,
green beans, spinach, broccoli, and rice with traceable,
non-radioactive stable isotopes. These isotopes, heavier
versions of common elements including calcium, iron
and nitrogen, can then be easily traced using special
instrumentation. Isotopically labeled plants are grown
in specially designed semiautomated, recirculating
hydroponics systems. |
