摘要： 0~4℃低温处理华兰氏甜瓜幼苗后，生长受抑，并在低温处理至第8天死亡；低温对扁豆幼苗生长虽也有明显影响，但幼苗生长尚未停止，只是变慢，在低温处理第24天死亡。检测华兰氏和扁豆幼苗期三种组织内ATPasc、COD和POD同工酶发现，华兰氏幼苗组织中三种酶的同工酶均产生变化，而扁豆中只有POD有谱带减少或活性变弱的现象。这一结果表明，华兰氏和扁豆两种作物幼苗生长受抑与其组织内同工酶的变化存在一定相关性。

Abstract: The cxparimtental results showed that low temperature (0-4℃ ) could inhibitc growth of muskmclon seedlings and change the contents of ATPasc, COD and POD isozymcs in the plant.For dolichos, the con-tents of POD isozyme changed, but the inhibitivc effect on seedling growth was not serious, under the low temperature significant correlation was demonstrated between the growth inhibitive effect and the changes of contents of ATPasc, COD and POD isozyme in muskmelon and dolichos.
