Evaluation of Storage Potential of Jatropha curcas L. Seeds

Abstract

Ensuring the physiological quality of the seeds depends on storage conditions. Since their quality cannot be improved, good conditions during this period will contribute on keeping them viable for a longer time, delaying the deterioration process. In the present study, the effect of five storage periods in a refrigerated chamber at 15˚C ± 1˚C, on the seeds viability during 30, 60, 90, 150 and 240 days of storage in glass containers was evaluated. Four replicates of twenty-five seeds per treatment were used and the data were compared by regression equation. It verified that, regardless of the storage time, the seeds when submitted to the drying temperature of 35˚C and 40˚C showed a significant linear reduction of germination, GSI and seed vigor after storage.
