Preliminary Investigation on Crop Growth, Physiology, and Yield of Rice under Partial Root-Zone Irrigation

Figure 3

Leaf gas exchange measurements of rice crop under the split root experiment. Changes in leaf photosynthetic rate (P_N) (a), stomatal conductance () (b), intercellular CO₂ concentration (C_i) (c), and transpiration rate (T_r) (d) at different partial root-zone irrigation treatments. Error bars indicate one standard error of the mean. Different letters denote significant differences among means derived using an ANOVA and Student’s t-test.
