Description :
Five genotypes Black gram were sown during 2016. The seeds after harvesting, threshing and processing were evaluated for their hardseededness dormancy. The findings of the present study indicate that concentrated sulphuric acid, hot water, sand scarification and hot air oven methods are effective for reducing hardseededness in Black gram. All the above mentioned treatments showed injuries effect to the seed embryo by increasing the dead seeds and abnormal seedlings except concentrated sulphuric acid treatment. In general concentrated sulphuric acid treatment for 60 seconds have been found most effective for breaking seeds coat dormancy and also significantly highest germination percentage compared to the above mentioned treatments under taken in the present investigation.
Keywords: Black gram, dormancy, hard seed coat, germination, seedling vigour, field emergence.
