植物叶片水力学指标中的争议
Disputes on Hydraulic Indexes of Plant Leaves
摘要: 全球生态系统正面临着干旱加剧的挑战，提升关于量化植物对干旱耐受性的理论与实践在目前显得尤为重要。膨压丧失点(πtlp)被视为决定植物干旱耐受性的关键生理因素，然而膨压丧失点的调节基础理论一直存在着争议；此外，叶片膨压丧失时的相对含水量与细胞壁弹性模量在植物耐旱性中起到何种作用仍不明确。在全球气候变化的背景下，对叶片水力学性状调节背后机理的澄清十分重要。
Abstract: Increasing drought is one of the most critical challenges facing ecosystems worldwide, and improved theories and practices are needed for the quantification of species tolerances. Leaf water potential at turgor loss (πtlp) is classically recognised as a major physiological determinant of plant water stress response. However, the basic theory of adjustment πtlp has been controversial. In addition, the role of relative water content at turgor loss point and cell wall elastic modulus in plant drought tolerance is still unclear. In the context of global climate change, it is important to clarify the mechanism behind the regulation of leaf hydraulic properties.
