- Explanation
of Services:
Form
for Submitting a Service Sample (Non-Certified)
- Regulatory Samples.
Samples which are drawn by the Plant Board in accordance with
procedures as outlined in the Regulations. Samples are taken
from seed that has already been labeled and is in the trade
channels. The purpose of regulatory samples is to ensure that
the seed has been correctly labeled (consumer protection).
- Service
Samples. Samples which
are submitted to the Plant Board for testing. Information from
test results may be used to label seed.
There are two kinds of service samples:
Certified Samples Samples
which are produced from crops that are in the Certification Program.
This seed was field inspected by the Plant Board and has met field
standards. The samples must be taken by Plant Board staff and
must pass the strict standards of laboratory testing before being
allowed to bear the official Arkansas Certified label.
Non-Certified Samples
Samples of seed which were not grown under an application for
Seed Certification or do not meet the requirements under the Certification
program. Samples may be submitted by the seedsman/farmer.

Explanation of Tests:
Complete Analysis (Comp)
Consists of the determination of the % pure seed, % weed seed, %
other crop, % inert matter, % germination, and the number and kind
of noxious weeds found in the sample per pound. Samples which are
under consideration for Certification are also tested for % moisture
and varietal purity.
Germ Only (GO)
Consists of the determination of the % germination. Germination
is the emergence & development of those essential structures
which indicate the ability to produce a normal plant under favorable
conditions.
Purity Only (PO)
Same as a complete except the % germination is not determined.
Varietal Purity (VP)
The determination of the presence of varietal contaminants. (Certified
Seed Only)
Noxious Weed Exam (NWE)
Consists of the determination of the number and kind of noxious
weeds found in the sample per pound.
Red Rice Exam (RRE)
Consists of the determination of the number of Red Rice found in
the sample per pound.
Seed Characteristics Exam
The determination of the general characteristics such as hilum color,
grain length, etc., for non-certified samples designated as to variety.
Vigor
Tests
Seed vigor comprises those properties which determine the potential
for rapid uniform emergence and development of normal seedlings
under a wide range of field conditions.
Varietal
Tests
There are several aids which enable the analyst to determine, confirm,
or group seed as to variety based on numerous tests.
Tetrazolium
Tests
A chemical "quick test" to estimate germination potential
for conditioning decisions.
Herbicide
Tolerance
The determination of tolerance to certain herbicides such as Roundup®.
