摘要
对冬小麦生育后期 F_1个体的杂种优势进行了研究,初步表明旗叶叶片衰老时,膜脂过氧化程度较低,内源活性氧清除系统仍维持较高活性,以及光合午休程度较低是 F_1杂种优势的两个生理表现。
The physiological bases of heterosis was studied during development and senescence of wheat flag leaves.The re- sults indicated that hybrid F_1 had lower lipid peroxidation degree,higer activity of scavenging active oxygen,and Rower degree of midday depression of photosynthesis,as was compared with its parents.
