摘要：

A theoretical model of the daily net photosynthetic rate (kg glucose/day) of a tree is formulated as an analytical function of certain agricultural and meteorological variables. The experimental, single-leaf rate (kg glucose/m2 leaf area - day) is integrated over both the tree canopy and the photoperiod for spherically and cubically shaped canopies. Consideration is given to cloud cover and mutual shading, one tree by another. Results are analyzed with respect to the efficiency of light energy conversion by a tree and variations in tree canopy height and shape. Quantitative comparisons with experimental data are made, primarily for the case of orange trees. Proportions of leaf photosynthate allocated to various tree parts are generated. © 1979.
