We introduce a few new technologies in Seed Technology using
computers.
The first example is our Seed Vigor Index System. As many of you
know, seed germination performance is dependent on many factors.
Currently, analysts
perform vigor tests to determine seed lot performance. The result of each
test, even when done by experts, varies frequently from
laboratory to laboratory. We are trying to standardize this test by
using computer image analysis techniques. We are hoping that
this process will eliminate human subjectivity, while serving as a useful
productivity tool for seed analysts.
The second area we are working on is seed purity testing. Every
shipment is required to be inspected for purity testing. Computers can
help seed analysts
in identify noxious seed identity by matching suspicious seed shape
information with that stored in the database. Initially, the computer
is trained to remember specific types of seeds based on various
morphological characters such as shape and texture. Then, the computer
is presented with a seed whose identity is unknown. If it is in the
types of seeds that it has learned, the computer can name what that seed is
with a high accuracy.
