THE EFFECTS OF LOW TEMPERATURE ON SEEDLINGS GROWTH AND THE CHANGES OF ISOZYMES IN THREE CROPS

In this experiment, the growth of seedlings and roots were obviously inhibited when seedlings of Phaseolus angularis and P. radiatus were exposed to 0─4℃for 1─2 weeks, but the growth of Glycine max (L.) Merr. had not completely been inhibited. The changes in PODand ATPase isozymes of roots have been observed when seedlings were exposed to 0─4 ℃ for 1─2 weeks. The relationship between inhibited growth of seedlings and changes of POD, ATPase isozymes in three crops which were cultured at low temperature (0─4℃)was obvious.
