Abstract: Photosynthetic characters of flag leaf blade such as photosynthetic rate (Pn), transpiration rate (Tr), stomatal conductance (Cs), intercellular CO2 concentration (Ci) and stomatal limitation (Ls), dry matter accumulation, and yield components per plant were studied on two wheat cultivars with diffe
