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.
Fig. 2 Comparisons of major nutrients and pH value in rhizospheric soils 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 0.01 level, and not significant, respectively. SA, semi-arid; SH, sub-humid.
Fig. 3 Comparisons of dissolved nutrients in rhizospheric soils between two climatic conditions (mean ± SD, n = 3). ** indicate that the differences between semi-arid and sub-humid conditions are significant at the 0.01 level. SA, semi-arid; SH, sub-humid.
