| 摘 要： | 测定小麦旗叶光合特性,比较乌鞘岭地区分期播种陇春8号小麦的光合生理日变化特征.结果表明:净光合速率、水分利用效率随播种期推后有增大趋势.在日变化过程中,上午蒸腾消耗少,水分利用效率高,光合能力比下午强,且有光合"午休"现象.不同播期春小麦光合要素与温度高低有关,在气温较高时段,温度与净光合速率、水分利用效率呈负相关,气...

| Abstract: | An experiment was conducted to measure photosynthetic elements of flag leaves and compare the characteristics of diurnal variation about photosynthetic physiology on various sowing dates of wheat named Longchun 8 in Wushaoling.The results show that the net photosynthetic rate and water utilization have increasing trends after pushing their sowing dates.In process of diurnal variation,the transpiration rate is less,water utilization is higher,and photosynthetic rate is stronger in morning than in afternoon,w... |
