Figure 4.
(A) Mesophyll (gm) and (B) total (gtot) conductance to CO2 in giant reed (Arundo donax L.) after waterlogging (Wlg) and submergence (Sub) treatment at each time point (4, 7, and 10 DOT) and after 3, 6, 24, and 72 h of recovery for each treatment and control (CTR). The dot in the box and whiskers plot indicates the arithmetic mean of six replicates. (C) Relationships of CO2 assimilation rate (A) with stomatal (gs), mesophyll (gm), and total (gtot) conductance. Pearson correlation coefficients (R) and significance level (p) of the linear regressions are shown.
