摘要
将玉米晚熟品种吉单１５９三叶期幼苗进行６℃、１０℃低温处理３天、６天，发现幼苗脯氨酸含量明显增加，电导率提高，可溶性蛋白含量随着低温处理时间的延长先增加后减少，叶绿素ＳＰＡＤ值减少，光合速率下降．
Puting the 3rd-leaf stage seedling of late variety of corn,Jidan
159 in the low temperature of 6℃ and 10℃ to treat for 3 and 6 days, it is shown that the proline
content is increased obviously, and the electric conductance is also raised.The content of
solubility protein is increased firstly and then decreased with the prolongment of treatment
time.The SPAD value of chlorophyll is decreased,and the photosynthetic rate is decreased.
