ABSTRACT

In the present investigation, seeds of Bixa orellana were subjected to various treatments to achieve early germination by breaking dormancy. So, the highest germination percentage (87%) was recorded for the seeds treated with IAA followed by 76% which was achieved in the seeds subjected to hot water pretreatment on the 17th day after sowing. The germination percentage was 17, 23, 20, 47, 27, 21, 27, 18, 35, 40, 22, 44, 21 and 64 in the seeds respectively kept as control, subjected to scarification, stratification, alternating high and low temperature, KNO3, thiourea, kinetin, GA3, H2SO4, pre-soaking, electric current, mechanical injury, coumarin and brassinolide treatments for the same time period. Thus, for achieving higher germination percentage for the seeds of B. orellana, treatment with IAA is the best option.
