低温处理对三种作物幼苗生长及组织内POD、ATP_（ase）同工酶的影响

THE EFFECTS OF LOW TEMPERATURE ON SEEDLING GROWTH AND POD.ATP_(ase) ISOZYMES IN THREE CROPS

为了研究三种作物中ＰＯＤ、ＡＴＰａｓｅ同工酶的变化与低温忍耐的关系，我们将三种作物幼苗在０—４℃低温下处理１周，然后检查三种作物根系中的ＰＯＤ、ＡＴＰａｓｅ同工酶，结果发现，低温处理下的三种作物根系中的ＰＯＤ同工酶谱带减少，该同工酶的变化与作物的耐低温能力存在一定的相关性。

In ordre to investigate the relationship between the changes in POD.ATPase isozyme and chilling──tolerance in three crops.We have examined the root POD.ATPase isozymes in seedlings which were treated by 0-4℃ low temperature for one week.Results show that POD isozyme bank of root decreased in number when seedling are culture at 0-4℃ low temperature and there is relationship between the change ofPOD isozyme and chilling-toiarance time peirod.
