Leaves are a nexus for the exchange of water, carbon, and energy between terrestrial plants and the atmosphere. Research in recent decades has highlighted the critical importance of the underlying biophysical and anatomical determinants of CO and HO transport, but a quantitative understanding of how detailed 3D leaf anatomy mediates within-leaf transport has been hindered by the lack of a consensus framework for analyzing or simulating transport and its spatial and temporal dynamics realistically, and by the difficulty of measuring within-leaf transport at the appropriate scales. We discuss how recent technological advancements now make a spatially explicit 3D leaf analysis possible, through new imaging and modeling tools that will allow us to address long-standing questions related to plant carbon-water exchange.
叶片是陆地植物与大气之间进行水、碳和能量交换的枢纽。近几十年来的研究强调了 CO 和 HO 传输的基础生物物理和解剖学决定因素的关键重要性，但由于缺乏用于分析或模拟传输及其空间和时间动态的共识框架，以及在适当尺度上测量叶片内传输的困难，因此对叶片内传输如何详细调节的定量理解受到了阻碍。我们讨论了最近的技术进步如何通过新的成像和建模工具使叶片的空间显式 3D 分析成为可能，这将使我们能够解决与植物碳-水交换有关的长期问题。
