ABSTRACT
In the present investigation, seeds of Mucuna pruriens were subjected to various treatments to achieve early germination by breaking dormancy. It was found that on 17th day after sowing, the germination percentage was 4, 32, 40, 17, 23, 27, 18, 28, 31, 35, 40, 17, 28, 74 and 82 respectively under untreated seeds and those subjected to hot water, scarification, stratification, alternating high and low temperature, KNO3, thiourea, kinetin, GA3, H2SO4, pre-soaking, electric current, coumarin, brassinolide and IAA. In this way, mechanical injury of the seeds of M. pruriens is the best option for achieving higher germination percentage. IAA is also a useful method as it induced 82% germination in the present study (table-1).
