图4 不同处理开花后旗叶净光合速率、蒸腾速率、气孔导度和胞间二氧化碳浓度 A、C、E、G分别表示2019-2020生长季开花后旗叶净光合速率、蒸腾速率、气孔导度和胞间二氧化碳浓度, B、D、F、H分别表示2020-2021生长季开花后旗叶净光合速率、蒸腾速率、气孔导度和胞间二氧化碳浓度; 图中所示数据均为每处理测定的3次重复, *、**表示不同处理在0.05和0.01概率水平差异显著。

Fig. 4 The net photosynthetic rate, transpiration rate, stomatal conductance and intercellular carbon dioxide concentration of flag leaf after anthesis under different treatments A, C, E, and G represent the net photosynthetic rate, transpiration rate, stomatal conductance and intercellular carbon dioxide concentration of flag leaves after anthesis in the 2019-2020 growing season, respectively; B, D, F and H represent the net photosynthetic rate, transpiration rate, stomatal conductance and intercellular carbon dioxide concentration of flag leaves after anthesis in the 2020-2021 growing season, respectively. The data shown in the figure are all three replicates of each treatment. * and ** indicate significant differences between different treatments at the 0.05 and 0.01 probability levels, respectively.
