Effect of storage period and type on seed quality and vigor attributes of some Egyptin cotton varieties (Gossypium baradense L.)
Abstract: Laboratory and field tests were conducted to determine the chemical composition and to investigate the effect of storage oeriod and type on the seeds of two extra long stable and four other long stable varieties of Egyptian cotton Gossypium baradense L. Random seed samples from the tested varieties were exposed to storage under room temperature and under deep freezing (-20ºC) conditions for two years. The stored samples were subjected to chemical composition analysis and to vigor testing including the determination of free fatty acids and accelerated aging to each storage period, as well as the field emergence. Generally, there was great deal of variability between seed classes, varieties, type and period of storage. This variability may not be unexpected since the breeding of this crop focuses on the lint quality more than any other aspect. These were significant differences between storage periods as fresh production performed better in the free fatty acids percentage and generally in the vigor testing values. Under the deep freeing storage conditions, seeds require drying to the safe limits before cold storage in addition to the separation of the mechanically damaged seed. Hence, these precautions affect the performance under these conditions
