植物叶片的蒸腾作用被认为是由叶片吸收的净辐射驱动的气体扩散过程。对蒸腾过程进行了解析表述，并给出了特定环境条件下所需的蒸腾速率。蒸腾作用受叶片内部扩散阻力的限制；报告了一些本地物种的抗性值。在温暖的夏季，光合作用和蒸腾作用的午间衰退经常发生，这可以从与高叶片温度相关的生物化学-生物物理基础上解释。
Transpiration from a plant leaf is considered as a gaseous diffusion process driven by the net radiation absorbed by a leaf. The transpiration process is formulated analytically and the required transpiration rates are given for specified environmental conditions. Transpiration is limited by the internal diffusion resistance of a leaf; values of the resistance are reported for a number of native species. The midday slump of photosynthesis and transpiration, which often occurs during warm summer days, can be explained on a biochemical-biophysical basis related to high leaf temperatures.
