Figure 3.
The value of Ci (A-C), Ci /Ca (D-F) and WUE (G-I) of three rice cultivars grown under control, ambient conditions; e[CO2], elevated CO2 concentration; warming, elevated air temperature; e[CO2] plus warming, the combination of elevated air temperature and [CO2]). SH, HJ and LJ represent rice cultivars Shishoubaimao, Hejiang 19, and Longjing 31, respectively. Values are the means ± SEs (n = 6). Different letters indicate significant differences between treatments at P < 0.05 level. Ci , intercellular [CO2]; Ci /Ca , the ratio of intercellular [CO2] to ambient air [CO2]; WUE, water use efficiency.
