| 中文摘要: |
| 选择典型的冷型小麦和暖型小麦为材料,通过测定功能叶净光合速率、群体冠层温度、叶片叶绿素含量、可溶性蛋白及超氧化物歧化酶等指标,研究干旱条件下不同温度型小麦开花后旗叶衰老特性。结果表明,在籽粒灌浆期间,冷型小麦叶片叶绿素含量、净光合速率、可溶性蛋白、超氧化物歧化酶等含量变化明显优于暖型小麦,在籽粒灌浆后期表现尤为明显。因此,在小麦生产中,可以借助群体冠层温度作为衡量小麦代谢的功能指标,为旱地小麦育种和栽培提供理论依据。 |
| 英文摘要: |
| The study has been conducted for three years to observe canopy temperature and biological characteristics of cold type wheat and warm type wheat under drought. The results showed that the canopy temperature o f cold type wheat is continuously lower than that of control , especiall y during milk filling stage. Many other characters, such as chlorophyll cont ent, net photosynthetic rate, soluble protein content and SOD activity, are rema r kably superior to those of warm type wheat. So the canopy temperature can be u sed a functional index in wheat breeding and culture under drought condition. |
