Abstract:Cassava (Manihot esculenta Crantz), an important tropical crop, is affected by extreme climatic events, including rising CO2 levels. We evaluated the short-term effect of elevated CO2 concentration (ECO2) (600, 800 and 1000 ppm) on the photosynthetic efficiency of 14 cassava genotypes. ECO2 significantly altered gaseous exchange parameters (net photosynthetic rate (Pn), stomatal conductance (gs), intercellular CO2 (Ci) and transpiration (E)) in cassava leaves. There were significant but varying interactive eff… Show more
