Abstract: The seeds of rape variety green petiole F1 treated with different temperature and duration. The results indicated that the difference of treatment temperature and time on the germination rate of rape seeds was significantly affected by the addition of 60 ℃4 h.Seedling emergence rate and the ratio of the film were highly significant level.50 ℃ ,4 h after the hot processing plant height of seedling increased 0.39% than the control group. Leaves number increased by 11.11% than the control. The maximum leaf area and root fresh weight compared with increased 2.2% and 16.32% respectively.50 ℃, 12 h after processing the root fresh weight increased by 17.16% than the control group. After processing of aboveground fresh weight was lower than control group,but 60 ℃, 12 h treatment of aboveground fresh weight of the highest. The plant height, number of leaves, maximum leaf area,fresh weight of both aboveground part and underground part of plants were significantly increased with treatment 50 ℃. Therefore 50 ℃ was the best treatment for rapeseed treatment.
