TEMPORAL VARIATION IN SEED QUALITY OF BRINJAL PRESERVED IN DIFFERENT STORAGE CONTAINER

The experiment was conducted to investigate the seed quality of Brinjal for three months stored at different containers (Tin container, polythene bag and cloth bag) during October to December, 2008 at Seed Technology Laboratory of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur. The initial moisture content of the seed was 10.84% with 90.50% Relative humidity. However, after two months, the seed had a different range of increased moisture content with reduced germination percentage depending upon the packing materials. Among the three containers, seeds stored at cloth bag absorbed more moisture (12.95%) from surrounding atmosphere followed by the moisture content, 12.50% and 11.79% of tin container and polythene bag, respectively. Seeds stored at tin container, polythene bag and cloth bag exhibited 60 percent germination. Similarly, the fresh weight and dry weight of seedling and seedling vigour were also decreased. The seeds of tin container were good in term of germination capacity, fresh and dry weight and vigour index in comparison to those stored at cloth bag and polythene bag.
