Abstract

An experiment was done in the research laboratory of Tehran university in order to evaluate the effect of various conditions of seed storage on storability of rapeseed primed seed. The experiment factors have included the seed priming using .05% lotion of KNO3 for 12 hours (primed and non primed with a this lotion)–package (vaccum packaging, nano and aluminium bags)–seed storage condition including: moisture content (5, 9, 13 and 17 %), temperatures(15 and 30) and storage periods(1,2,3,4,5 and 6 months). Analysis of variance demonstrated that with increasing the duration of storage and also with increasing seed content humidity amount and storage temperature, the seeds vigour would be decreased and in studing indexes, this decrease occurred in the first month of storage in 17% seed water content and 30 C temperature treatment and not in other onces, which shows that storage condition in more important in storage than other factors. For all indices, germination rate and percentage in rapeseed seed, there were significant differences in main, double and triple interaction effects at 1% probability level. the nano packagings is usually suggested as a suitable packaging to preserve the seeds in these condition.
