On the physiology of plant transpiration

该项目旨在更好地了解植物蒸腾作用。从基本和实践的角度来看，这都具有重要意义。它打算解决树叶内蒸发部位的生物物理难题。也就是说，在干燥的空气中，细胞间空气空间的相对湿度表明液体水势比通常测量的要低得多。在实践层面上，在干旱条件下不能维持蒸腾作用会导致干燥和组织死亡，植物在这方面的脆弱性有所不同。其目的是应用一种新的纳米颗粒技术来测量叶片内的水势分布，识别水力弹性属性，并发展一种在不同条件下最佳蒸腾作用的现代理论。

This project aims to better understand plant transpiration. It is significant from both a basic and a practical perspective. It intends to solve a conundrum of the biophysics of the evaporative sites within leaves. That is, in dry air, the relative humidity of intercellular air spaces suggests much lower liquid water potentials than those typically measured. At a practical level, the failure to sustain transpiration in dry conditions leads to desiccation and tissue death, and plants differ in this vulnerability. The aim is to apply a novel nanoparticle technique to measure the water potential distribution within the leaf, identify hydraulic resilience attributes, and develop a modern theory of optimal transpiration under varying conditions.
