Figure 5From: Responses of photosynthetic capacity to soil moisture gradient in perennial rhizome grass and perennial bunchgrassResponses of F v / F m (A, C) and F' v / F' m (B, D) 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. Different lower case letters represent significant differences from water status according to Duncan's multiple range test.Back to article page
