中文摘要：

根据人工气候室，高温的效果(每天平均的温度 25 ， 30 ， 35 和 40 °C ，分别地)在抗氧化剂酶和类脂化合物上，每在旗帜的氧化，在50%亲戚的小麦的叶子在最快充满舞台的谷物期间让潮湿通风[在开花期( DAA )以后的 19 21 天]被学习。测试的小麦栽培变种是 Yangmai 9 与弱面筋并且 Yangmai 12 与中等面筋。与 25 ° C 相比，温度越高，当更低时，越多 higher 是在旗帜叶子的 MDA 内容是草皮，邮政部门，和猫活动。在 Yangmai 12 的草皮和猫活动看起来在 Yangmai 9 比那对高温更敏感。但是在 Yangmai 12 的邮政部门活动对高温不太敏感。在 Yangmai 12 的 MDA 内容在 Yangmai 9 比那高。1000 谷物重量随温度的增加衰退了。

英文摘要：

On the basis of the phytotron, the effects of high temperature （daily average temperature 25, 30, 35 and 40℃, respectively） on antioxidant enzymes and lipid peroxidation in flag leaves of wheat at 50% relative air moisture during grain fastest filling stage [19-21 days after anthesis （DAA）] were studied. The wheat cultivars tested were Yangmai 9 with weak-gluten and Yangmai 12 with medium-gluten. Compared with 25℃, the higher the temperature was, the higher was the MDA content in flag leaves, while lower were the SOD, POD, and CAT activities. SOD and CAT activities in Yangmai 12 appeared to be more sensitive to high temperature than that in Yangmai 9. But POD activity in Yangmai 12 was less sensitive to high temperature. MDA content in Yangmai 12 was higher than that in Yangmai 9. The 1000-grain weight declined with increase in temperature.
