Figure 4
Responses of maximum gross CO 2 assimilation rate ( A g,maxt , A, D), maximum carboxylation velocity ( V c,max , B, E), and maximum rate of electron transport ( J max , C, F) in L. chinensis (A-C) and S. grandis (D-F). Vertical bars represent ±SE of the mean (n = 3-5) where these exceed the size of the symbol. Note different scales and units in y-axes. Different lower case letters represent significant differences from water status according to Duncan's multiple range test.
