Description :
Five genotypes of Lathyrus were sown during 2015. The seeds after harvesting, threshing and processing were evaluated for their hardseedness 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 hardseedness in Lathyrus. 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 seconds have been found most effective for breaking seeds coat dormancy and also significantly highest germination percentage compared to the above mentioned treatments undertaken in the present investigation.
Keywords: Lathyrus, dormancy, hardseed coat, germination, seedling vigour, field emergence.
