The Impacts of Low Temperature on Corn Seedling Physiological Response
-
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。Abstract: Putting 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.
