图2. 古尔班通古特沙漠2物种6、7月的冠根比(平均值±标准差)。不同大写字母表示同一层次(地上或地下)的不同生长季对比差异显著(p < 0.05); 不同小写字母表示同一生长季的不同层次对比差异显著(p < 0.05)。
Fig. 2. Shoot-to-root ratio of two species in Gurbantünggüt Desert in June and July (mean ± SD). Different uppercase letters indicate significant differences (p < 0.05) between different growing seasons for the same level (above or below ground); different lowercase letters indicate significant differences (p < 0.05) between different levels in the same growing season.
