Figure 8. Changes in the photosynthetic machinery in leaves of lowland and upland rice under control and drought stress conditions.

(A) Rates of photosynthesis in leaves of lowland and upland rice under control and drought stress conditions. (B) Stomatal conductance in leaves of lowland and upland rice under control and drought stress conditions. (C) Intercellular CO₂ concentration in leaves of lowland and upland rice under control and drought stress conditions. (D) Transpiration rate in leaves of lowland and upland rice under control and drought stress conditions. LC-Lowland rice under control condition; LS-Lowland rice under stress condition; UC-Upland rice under control condition; US-Upland rice under stress condition (Multiple compare test of mean for the four cases was used as a statistical test and the 0.05 statistical significant threshold was chosen.).
