图1. 两种气候条件下植物器官主要养分含量的比较(平均值±标准偏差, n = 3)。*、**和ns分别代表半干旱和半湿润条件下显著性水平小于0.05、小于0.01和不显著。BL, 枝和叶; Root, 根系。SA, 半干旱; SH, 半湿润。
Fig. 1. Comparisons of major nutrients in plant tissues between two different climatic conditions (mean ± SD, n = 3). *, ** and ns indicate that the differences between semi-arid and sub-humid conditions are significant at the levels of 0.05 and 0.01, and not significant, respectively. BL, branches and leaves; Root, roots. SA, semi-arid; SH, semi-humid.
