Abstract: The effects of direct and diffuse lights on the leaf-side-specific regulation of photosynthesis were studied in sorghum, a typical C4 plant. Leaf morphology and structure were carefully investigated by semithin cross section of sorghum leaves. Leaf absorption, transmittance and reflectance profiles were similar on the adaxial and abaxial leaf surfaces across the light spectrum from 400 to 800 nm, whether light was illuminated via the adaxial or abaxial surface. The photosynthetic light-response curves showed that maximal whole photosynthetic rates were higher when the light entered the leaf via the adaxial surface than the abaxial surface. The changing trend of stomatal conductance was similar with photosynthetic light-response curves. However, the maximal photosynthetic rates were much lower when the light entered the leaf via the abaxial surface than adaxial surface when blocking the stomata of light-oriented side by PE membrane. Theintensity of direct and diffuse lights varied widely in a day, and that of diffuse light was significantly lower than light compensate point (Ic) of abaxial leaf surfaces in sorghum. Consequently, photosynthetic rate of abaxial leaf surface in sorghum should be mainly droved by self-transmitted light but not diffuse light. Differences in stomatal density, substomatic cavity, contacting areas between bundle sheath and mesophyll cells are related to this feature of abaxial leaf surfaces. is the findings of the present study are important for field management, investigation of ecosystem productivity and breeding for high photosynthetic efficiency.
