A new and faster vigor test system utilizing computer-imaging techniques from
The Ohio State University to assess soybean seeds for vigor is now available
from OSIA. The advantage of computerized seed vigor assessment over that done
by humans is that results can be obtained much faster in an objective manner.
The current system operates in the following way. Seeds are either germinated
under recommended standardized conditions for three days or following an
Accelerated Aging test at high temperature and relative humidity for three days
and the seeds germinated for an additional three days. After this period, an
image is taken of the seedlings using a scanner in a special enclosure and the
digitized image is fed into the computer. The computer software then analyzes
and computes objective parameters such as overall seedling length and
determines total seedling length and uniformity. Once the measurements of
individual seedlings are computed, the seed vigor of the sample is calculated
by considering individual seed development as well as sample population
statistics such as uniformity.
Additionally, SVIS training is available for organizations that may want to
introduce this technology into their own inhouse labs. For more information,
please contact OSIA.
