Abstract

WILD OAT has two seeds in a spikelet that they have different physiological behavior in regard of seed germiantion. The upper seed of spikelet is smaller and has deeper dormancy than the lower seed. The range of temperature for GERMINATION is 5°C to 25°C and optimal temperature is 15°C. Both kinds of seeds showed the more germination rate in low temperatures so that 5 and 10°C are better for germination than that of 20 and 25°C.Germination was late and slow in 5°C. This study reveled that alternative temperatures (15:5°C) was the optimal condition for seed GERMINATION. After one and two months, chilling caused 63.5% and 97% GERMINATION rate in the lower seeds respectively. Also it caused 11.5% and 92% GERMINATION rate for upper seeds. The results showed that chilling for two months was necessary for SEED DORMANCY breaking. Nitrate ions caused 32.75% GERMINATION rate in upper seeds and 57.25% GERMINATION rate in lower seeds as compared with those of to controls which were 11.5% and 13.75% respectively. GA3 was more effective factor in GERMINATION as compared with that of Nitrate ion and cytokinin. Soil stiring caused more GERMINATION in burried seeds in different depths of soil.
