摘要
低温可能引起细胞膜和内膜系统的透性及功能发生改变,也可能引起细胞代谢水平发生改变,这些改变都可引起细胞质中和NO3-HADH水平及ATP水平的改变,所以其体内硝酸还原酶活性必然受影响。2叶期玉米受冷害后,叶片中的硝酸还原酶活性显著增加,并且有光冷害处理比无光冷害处理更有利提高叶片中硝酸还源酶的活性。
The transmissivity and function of the cell membrane and system inside the membrane,and also the level of cell metabolism in the seedling of maize can be changed by the low temperature.The change can influence the content of NO 3- ,HADH and ATP in the cell cytoplasm,and also the active of reductase in the seedling conse-quentially.The active of nitric acid reductase in the leaf can enhance remarkably after cold damage in the two-leaf stage.The cold treatment in light can conduce to enhance the active of nitric acid reductase in the leaf than in dark.
