Table 2 Optimum temperature (Topt) and light
saturated photosynthetic rate at Topt(Aopt) of cotton plants across temperature (Temp) and
water deficit (Water) treatments. Data are shown as mean ± standard
error of mean (n=6). Also given are the P-values of two-way ANOVA
showing the main and interactive effects of temperature and water
availability on two parameters, with significant effects displayed in
bold. Numbers differ in superscripts within the same column indicate
statistical difference at P ≤0.05 level.
