Abstract

A study was conducted to determine the effects of length of storage on the viability of wheat (Triticum sestivum L.) seeds.

Two types of container and two moisture levels in the seed were used in the study. Seeds dried to 11% and 14% moisture were placed in airtight bottles and paper envelopes and stored at ordinary room conditions. The percentage germination and vigor index were determined at monthly intervals for seven months following storage by growing the seeds in the greenhouse in seedboxes filled with ordinary soil.

Viability decreased with storage time. The airtight bottles however were better containers than paper envelopes in maintaining the viability of stored seeds. Percent germination and vigor index of seeds in paper envelopes were markedly reduced after the seven-month period with the most rapid decline noted after the fifth month. Seeds stored in airtight bottles showed only slight reduction in percent germination and vigor index and the rate of decline was not as rapid as seeds in paper envelopes. The data failed to show significant beneficial effects of drying seeds to 11% moisture prior to storage. Paper envelopes are not suitable for storing seeds longer than four months under ordinary room conditions.
