igna radiata (mogumah) and Vigna mungo (matimah) seeds loose vigour due to high temperature, if the moisture content of the seed is high as it is in state of Assam. Therefore, vigor loss due to heat and moisture is a common phenomenon in the region. Germination and vigour index of seed treated with NaBH4 and APS were found to be higher (3860%) than that of the seeds without chemical treatment. APS (1mM) was optimum for the germination of black gram as well as green gram. In case of NaBH4, 8mM was optimum for the germination of black gram and 1mM was optimum for the germination of green gram. We believe that the above two chemicals might be useful for stimulating germination of other seeds as well.
Keywords: Heat Stress; Vigour Index; Germination; Sodium Borohydride; Ammonium Persulfate; Synchronized Germination.
