Responses of plant (A, C) and leaf (B, D) biomass to soil relative water content (SRWC) for both L. chinensis (A, B) and S. grandis (C, D). Vertical bars represent ±SE of the mean (n = 3-5) where these exceed the size of the symbol, and different lower case letters represent significant differences from water status according to Duncan's multiple range test.
