| 摘 要： | 在不同水分条件下，对不同抗旱基因型小麦的产量及旗叶光合特性进行了比较研究。结果表明：在干旱胁迫条件下，洛旱2号的产量显著高于温麦6号，水处理条件下2个品种的光合速率、蒸腾速率、气孔导度和胞间CO2浓度均高于旱处理；在干旱胁迫条件下，洛旱2号的光合速率、蒸腾速率和气孔导度下降幅度均小于温麦6号。

| Abstract: | The yield and photosynthetic characteristics of flag leaf of different drought resistance wheat varieties under different water conditions were studied.The results showed that the yield of Luohan No.2 was significantly higher than Wenmai No.6 under drought stress.The photosynthetic rate,transpiration rate,stomatal conductance and intercellular CO2 concentration of the two varieties with irrigation were higher than that under drought stress.The decreasing rates of photosynthetic rate,transpiration rate and s... |
