Table 2.
Percentage of AM fungal root length colonization (hyphae, vesicles, and arbuscules) (mean ± 1 SE) at the end of the 1st and 2nd growing periods in microcosms subjected to moderate and high rain intensity. Different superscripts letters (a and b) indicate significant difference (p < .05) on hyphae, vesicles, and arbuscules between rain regimes (Tukey's post hoc test; p < .05)
