Abstract

Seed deterioration can occur by the length of the storage period or accelerated aging. Viability of seeds will be lower due to increasing seed deterioration. This experiment aimed to compare the viability of the seeds of two varieties of sorghum, Numbu and UPCA-S2, due to the natural storage period and due to accelerated aging. The intensity of aging was the increasing concentration of ethanol solution. Some seeds were stored in a r oom with temperature of 27,3 ± 0,9ᵒC and their viability ware observed periodically in every two months up to 6 months. Some other sorghum seeds were treated by moisturizing them in ethanol solution with increasing concentrations, 0, 4, 8, and 12%, each for 24 hours. Seed viability was observed at each end of the rapid aging treatment. The storage period and also the intensity of aging treatment significanty (P<0,01) reduced the percentage of normal seedling and speed of germination. The seed viability declined significantly at the aging treatment of 8% ethanol concentration, as well as at the treatment of storage period of two months. Keywords : ethanol, seed, sorghum, viability.
