Germination of Pennisetum setosum seeds was studied under light and dark conditions, at various temperatures ranging from 15 to 45 deg C, osmotic potential ranged from 0 to -10 bars, soil moisture contents ranged from 0 to 35 % (w/w) and pH ranged from 4 to 7. At constant temperature of 35 deg C, seed germination was not different under light and dark condition. Seeds could germinate only at the temperatures ranged from 20 to 40 deg C. At 20, 30 and 35 deg C, seeds germinated without any difference. In the moisture stress condition, seeds could germinate only at the osmotic potential of 0 to -6 bars. The optimum condition for germination were at 35 deg C, osmotic potential of 0 bars, 15 % (w/w) soil moisture content and pH 6.
