ABSTRACT
In the present investigation, seeds of Plantago ovata were subjected to various treatments to achieve early germination by breaking dormancy. The germination percentage 50, 91, 43, 35, 22, 27, 32, 46, 38, 41, 71, 28, 35, 33, 74 and 85 was respectively achieved for the seeds kept as control, treated with hot water, subjected to scarification, stratification, alternating high and low temperature, KNO3, thiourea, kinetin, GA3, H2SO4, pre-soaking, electric current, mechanical injury, coumarin, brassinolide and IAA on 17th day. For this plant species, the best results were obtained in the seeds subjected to hot water pretreatment which promoted as high as 91% germination.
