图2 干旱条件下导度损失率(PLC)和边材比导率变化(Ks) (平均值±标准差, n = 5)。不同大小写字母表示同一处理不同干旱时间存在显著差异。*表示在p < 0.05水平下相同干旱时间对照组和遮光组之间的差异显著。

Fig. 2 Percentage loss of conductivity (PLC) and specific hydraulic conductivity (Ks) under drought conditions (mean ± SD, n = 5). Different uppercase or lowercase letters represent the significant difference between the drought time of control or shading. * indicates the significant difference between the control and shading for the same drought time at the p < 0.05 level.
