Table I.

Opt (A360), Opt (Ac), Opt (Ar), Jmax/Vcmax, and Ci

The data shown are mean values for each species (see Supplemental Table S1 for each species). A repeated-measures ANOVA was used to test for statistical differences. P values from repeated-measures ANOVA are shown for differences between growth temperatures and between plant types and for interactions. NS, Not significant.
