Chlorophyll fluorescence and stable isotope signals in photosynthesis research

叶绿素a荧光和碳氧稳定同位素信号常用于研究光合作用的光能及水分利用效率。本文综述了叶片光合作用过程中的叶绿素荧光和碳氧稳定同位素信号的机理和研究进展,并阐述了叶片内部光环境和二氧化碳浓度的不均一性对这两种信号的影响,最后我们在展望中建议建立基于叶片三维结构及光合机理的模型,以支持对叶绿素荧光及稳定同位素信号的物理解释,促进其在光合作用研究中的应用。

Chlorophyll fluorescence and stable isotope signals are two major categories of signals used extensively in the study of light and water use efficiencies of photosynthesis.This review summarizes current progress and major theories for these signals.We further discussed the heterogeneity of light and CO_2 inside a leaf and how these heterogeneities influence these signals.To cope with this challenge of accurate interpretation of these signals from a leaf,we propose to establish a 3-D highly mechanistic model of leaf reaction diffusion models to help interpreting these signals and further promoting their application in photosynthesis research.
