摘要

The effect of five storage conditions viz., open, closed, partial vacuum, with calcium chloride and silica gel under three temperature regimes of 10 degrees C, 15 degrees C and ambient temperature were observed on freshly collected sal (Shorea robusta Gaernt. F.) seeds. The initial seed moisture content and germination was 45.5% and 100% respectively. Among all the storage conditions, seeds stored at 10 degrees C showed a rapid decline in moisture content upto 10 days. Maximum seed moisture retention was found with storage in closed and partial vacuum conditions at 15 degrees C after 50 days of storage, which also showed maximum viability/germinability (30% and 42% respectively). Statistically significant interaction was observed between storage temperature and storage period. Slow desiccation leads to good storage and longevity of seeds.
