Seed moisture content (MC) and
storage temperature are the most important factors affecting seed
longevity and vigor. Exposure to warm, moist air is principally
responsible for this. Proper storage and optimum seed moisture content
can affect the grain quality significantly. The purpose of this study
was to evaluate the different storage treatments on seed
quality of sorghum. The seed materials were fresh without any
storage period. For storage treatments, 3 seed moisture contents (6,
10, 14 %) were stored for 8 month in 0.5 L capacity sealed aluminum
foil packet in 0.3 bar inside incubators set at 4
temperatures (5, 15, 25, 35 °C). After storage time,
the higher the storage temperature, the lower was the grain
quality of sorghum. The highest germination percentage,
germination index, normal seedling
percentage were achieved in control
conditions (0 day of storage). Our
results showed that increasing storage
duration resulted higher reduction in
germination characteristics. Also our results showed that, germination
percentage, means time to germination, germination
index, normal seedling percentage
decrease significantly by storage. Enzyme activity
decrease significantly by increased in storage.
