Evaluation Of Mechanical And Chemical Treatments On Seed Coat Imposed Dormancy In Moth Bean
Five genotypes of moth bean 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 moth bean. 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.
