图2 骆驼刺(As)和梭梭(Ha)的叶功能性状随干旱程度的变化以及种间差异(平均值±标准差)。D1、D2和D3表示轻度、中度和重度干旱。大写字母是单因素方差分析的结果, 表示同物种的功能性状随干旱程度的变化, 不同字母表示显著差异(p < 0.05)。小写字母是独立样本t检验的结果, 表示在同一干旱程度下, 功能性状在梭梭和骆驼刺之间的差异, 不同字母表示显著差异(p < 0.05)。

Fig. 2 Variance of leaf traits across the drought levels and between Alhagi sparsifolia (As) and Haloxylon ammodendron (Ha) (mean ± SD). D1, D2 and D3 are mild, moderate and severe drought, respectively. Uppercase letters are the result of one-way AVOVA, different letters show significant difference under different drought levels of same species (p < 0.05). Lowercase letters are the result of independent sample t test, different letters show significant difference between species under same drought level (p < 0.05).
