Stomatal conductance correlates with photosynthetic capacity.
Relationship between mesophyll conductance and photosynthesis rate of four wheat cutivars in response to drought stress at two growth stages. Our results regarding the effect of drought stress on the C i were in agreement with Kicheva et al. The responses of g s , g m and C i in this study make clear that drought stress significantly decreases photosynthesis rates. Compared with g s , g m was found to be more sensitive to the drought stress. The weak relationship between P n and g s indicates that reduction in P n under drought stress can not be attributed to the stomatal closure alone.
