Conteúdo: | Net CO2 assimilation (A), stomatal conductance for CO2 (g), water-use efficiency (WUE), specific leaf density (Wa), and leaf chlorophyll and nitrogen (N) content were determined for mango (Mangifera indica L.) leaves that developed in full sun and 25%, 50%, and 75% shade. Leaves that developed in full sun had greater A and g, than leaves that grew in 75% shade. Leaf chlorophyll content and N content increased as percent shading increased, but WUE and W, were not significantly affected by shading. Light response curves for A had a steeper initial slope for leaves that developed in full sun and 25% shade than for leaves that developed in 50% and 75% shade. The data indicate a greater quantum-use efficiency for leaves developed in high light levels than for those developed in shade.
