Figure 1From: Responses of photosynthetic capacity to soil moisture gradient in perennial rhizome grass and perennial bunchgrassChanges in soil relative water content (SRWC) as plants were subjected to the five levels of soil water-withholding treatments (A), and leaf relative water content (RWC) as a function of gravimetrical water content (WC) (B) for L. chinensis (filled squares, solid line) and S. grandis (open squares, dashed line). Vertical bars in Figure 1A represent ±SE of the mean (n = 5) where these exceed the size of the symbol.Back to article page
