图2 不同水分条件下e[CO2]对冬小麦叶片气体交换参数的影响 A: 净光合反应速率; B: 气孔导度; C: 蒸腾速率; D: 水分利用效率。所有数据为平均值±标准差(n = 5), 误差线上不同字母表示两种[CO2]下8个水分处理之间有显著差异(P<0.05)。

Fig. 2 Effects of e[CO2] on leaf gas exchange of winter wheat under different water conditions A: net photosynthetic rate; B: stomatal conductance; C: transpiration rate; D: water use efficiency. Data are means ± SD (n = 5). Different letters above the error bars indicate significantly different (P < 0.05) among the eight water treatments under two [CO2] conditions.
