摘　　要：光学技术以它所特有的无损、快速和在位分析的优势，广泛应用于植物逆境生理监测和逆境胁迫机制研究。作为一类最主要的逆境胁迫，铝毒性是酸性土壤限制作物生长的主要原因。本文从光学分子成像和在位实时监测两个功能层面上概述了光学分析技术在铝毒生物学机制研究和铝毒性生理探测中的应用，并对其做了展望，同时，也讨论了铝毒性生物胁迫机制尚未涉及的问题，以期为铝胁迫机制研究提供有用的技术和理论参考。Due to their unique rapid and noninvasive natures, optical techniques have been widely used to monitor plant stress responses and to unravel the stress mechanisms in vivo. As one of the major adversity stresses, Aluminum toxicity is the major growth-limiting factor for crop production in acid soils, and its molecular mechanisms have been the focus of ongoing research in the area of stress physiology. In this paper, we summarized the actuality and viewed the out-look concerning the applications of optical techniques in monitoring the A1 stress responses and elucidating its stress mechanisms, in anticipation of providing some value insights, and technical references for studying A1 stress mechanisms.
