FIGURE 5

Mycorrhizal response of photosynthesis characteristic, including (A) net assimilation rate (A), (B) stomatal conductance (gs), and (C) intrinsic water use efficiency (iWUE) in L. chinensis and H. altissima. Mycorrhizal benefit existed when values of mycorrhizal response were greater than zero. Different lowercase and capital letters indicate significant differences (P < 0.05) among the rainfall exclusion treatments in L. chinensis and H. altissima, respectively. P < 0.05 and ∗∗P < 0.01 indicates significant differences and ns (P > 0.05) indicates no differences between L. chinensis and H. altissima. Data are reported as mean ± 1 SE (n = 4).
