Carbon dioxide transport through the hypostomatous plant leaf
JANOVÁ, Jitka
Mesophyll conductance is (together with stomatal conductance) a crucial component of diffusion limitations of photosynthesis and it is important to understand the mechanisms of CO2 fluxes through the leaves. Here I tested a new technique for estimation of drawdown in CO2 concentration across hypostomatous leaves based on carbon isotope composition (13C) of leaf cuticle and cuticular waxes isolated from opposite leaf sides.
Effect of light quality on diffusion limitations of photosynthesis
NEUWIRTHOVÁ, Jitka
Mesophyll conductance to CO2 transport is one of crucial components of diffusionall limitations of photosynthesis and is characterized by CO2 flux from sub-stomatal cavity to chloroplast stroma. Using Gas-exchange measurements A/Ci curves were analysed and by instantaneous carbon isotope discrimination mesophyll conductance was estimated. Measurements were conducted by sunflower irradiated with different light quality (blue, red and green component of photosynthetic active radiation).
