A theory of light relations in plant canopies is presented which has potential applications in remote sensing and photosynthetic modeling of plant canopies. Predictions of the model are compared with field measurements of light reflection and transmission in a corn crop. Both reflection at the top of the canopy and transmission at the bottom are predicted within 1% of the measured values. Profiles connecting these upper and lower limits are equally well approximated. Variations in the predictions with altitude angle of the sun are confirmed by the observation of several investigators.
提出了一种关于植物冠层中光关系的理论，该理论在植物冠层的遥感和光合建模方面具有潜在应用。将该模型的预测结果与玉米作物中光反射和透射的田间测量结果进行了比较。冠层顶部的反射和底部的透射预测值与测量值的偏差均在1%以内。连接这些上限和下限的曲线也得到了同样好的近似。几位研究人员的观察证实了预测结果随太阳高度角的变化。
