ABSTRACT
In the present investigation, seeds of Baliospermum montanum were subjected to various treatments to achieve early germination by breaking dormancy. It was found that, On 17th day, 88% germination was recorded in the seeds which were mechanically injured followed by 86% in the IAA treated seeds. It was 11%, 32%, 64%, 31%, 29%, 28%, 27%, 31%, 28%, 41%, 52%, 31%, 36% and 72% germination respectively in the seeds kept as control, those treated with hot water, scarification, stratification, alternating high and low temperature, KNO3, thiourea, kinetin, GA3, H2SO4, presoaking, electric current, coumarin and brassinolide. Thus, for B. montanum seeds, mechanical injury is the best option for achieving higher germination percentage, the other option being IAA (table-1).
