Exploring the Impact of Different Pre-treatment Methods on Overcoming Dormancy in Mucuna pruriens Seeds

Abstract

In the ongoing investigation, different treatments were applied to Mucuna pruriens seeds to encourage early germination by overcoming dormancy. Results revealed that on the 17th day after planting, various treatments were used, including hot water, scarification, stratification, alternating temperatures, KNO3, thiourea, kinetin, GA3, H₂SO₄, pre-soaking, electric current, coumarin, brassinolide, and IAA. The respective germination percentages were 4%, 32%, 40%, 17%, 23%, 27%, 18%, 28%, 31%, 35%, 40%, 17%, 28%, 74%, and 82%. Notably, mechanical injury proved to be the most effective method, resulting in the highest germination percentage of 88%. Moreover, IAA also demonstrated usefulness by inducing 82% germination.
