A physiologically based steady-state model of whole leaf photosynthesis (WHOLEPHOT) is used to analyze observed net photosynthesis daily time courses of soybean, Glycine max (L.) Merr., leaves. Observations during two time periods of the 1978 growing season are analyzed and compared. After adjustment of the model for soybean, net photosynthesis rates are calculated with the model in response to measured incident light intensity, leaf temperature, air carbon dioxide concentration, and leaf diffusion resistance. The steady-state calculations closely approximate observed net photosynthesis. Results of the comparison reveal a decrease in photosynthetic capacity in leaves sampled during the second time period, which is associated with decreasing ability of leaves to respond to light intensity and internal air space carbon dioxide concentration, increasing mesophyll resistance, and increasing stomatal resistance.
基于生理的全叶光合作用稳态模型（WHOLEPHOT）用于分析观测到的大豆（Glycine max (L.) Merr.）叶片净光合作用的日变化过程。对1978年生长季两个时间段的观测数据进行了分析和比较。在对大豆模型进行调整后，根据实测的入射光强、叶片温度、空气中二氧化碳浓度和叶片扩散阻力，用该模型计算净光合速率。稳态计算结果与观测到的净光合作用非常接近。比较结果显示，在第二个时间段采集的叶片光合能力下降，这与叶片对光强和内部气腔二氧化碳浓度的响应能力下降、叶肉阻力增加以及气孔阻力增加有关。
