Figure 3

Effect of exogenous calcium (Ca2+) and a calmodulin inhibitor (TFP) on peanut gas exchange characteristics [net photosynthetic rate (Pn, A), stomatal conductance (gs, B), transpiration rate (Tr, C), intercellular CO2 concentration (Ci, D), water-use efficiency (WUE, E) and leaf stomatal limitation (Ls, F)] during 5 days of low nocturnal temperature (1, 3, and 5 DoT) followed by 5 days of recovery (1, 3 and 5 DoR). Values are means of three biological replicates ± SE (n = 3). * and ** indicate significant differences at P ≤ 0.05, and P ≤ 0.01, respectively, among the treatments. The significance between the three treatments under LNT and CK was shown in parenthesis.
