The impacts of drying temperatures of 70, 60, 50, 40 and 22 deg C on changes in dormancy and germination of seed harvested with moisture contents of 45, 35 and 25% were observed in the present study. The analysis was done immediately after seed drying, then three months later and eight months later. Seeds with the moisture content of 45% that were dried at 70 deg C were not dormant at all after harvest, but seeds were damaged, which resulted in reduced germination. Drying temperatures of 40 deg C and 50 deg C resulted in maximum germination of seed harvested with 45% moisture after three months. After eight months the best germination of all seeds was obtained at 22 deg C and 40 deg C. The seed ageing test confirmed faster deterioration of seeds harvested with higher moisture contents. Seed harvested with 25% moisture and dried at 22 deg C is the most suitable seed for longer storage.
