| 摘 要： | 通过检测不同温度以及低温伴随降雨条件下玉米苗期各部位谷胱甘肽S-转移酶(GSTs)活性的变化情况,探究GSTs活性与玉米苗期药害发生的关系。结果表明,苗期玉米根、茎、叶部位GSTs活性存在明显差异,根部GSTs活性最高,茎部次之,叶部最低。低温会抑制玉米苗期根、茎、叶部位GSTs的活性。在低温伴随降水环境下,苗期玉米GSTs活性会进一步下降,降水72 h后,玉米各部位的GSTs活性逐渐回升。

| Abstract: | The effects on the activity of GSTs in maize seedling at different temperature and precipitation at low temperature were investigated. The result indicated that, GSTs activity took remarkable differences between the root, stem and leaf in maize seeding, the root was the highest, the stem was second, the lowest was the leaf. The activity of GSTs in maize seeding decreased at low temperature. Under the conditions of low temperature and precipitation, GSTs activity in maize seedling decreased further. After 72 hours, the activity of GSTs in different parts of maize seedling increased gradually. |
