Effects of different soil phosphorus and water contents on cotton root length and hyphal density (two factor analysis of variance). Different letters above bars indicate significant differences in the phosphorus (white column) or water (gray column) contents at the 0.05 level. Error bars represent the standard error of the mean (n = 6) (same as in Fig. 3)
