| Abstract: | In order to solve degradation problems during the cultivation of Ipomoea batatas,tender buds were used as the explant in vitro culture to study rooting,transplanting and field planting of test-tube seedlings.Before transplanting,test-tube seedlings were treated twice under the condition of 38℃ and each treatment lasted 15 days.The results showed that the optimum medium for rooting and subculture was 1/2MS＋ IAA0.2 mg·L-1＋ sucrose 15 g·L-1.After twice heat treatment,some vigorous growth test-tube seedlings could still survive and grow out of young shoots.The test-tube seedlings which cultivated from the heat-treated young shoots could transplant and field planting easily.Compared with plantlets issued from the shoots cuttings,the harvest yield of heat-treated test-tube seedlings could add fifty percent under the same cultivate condition. |
