葉綠素螢光在植物逆境生理研究的應用

The Application of Chlorophyll Fluorescence in the Study of Plant Abiotic Stresses

環境逆境促使植物改變形態結構、生理代謝及養分運輸，以提高存活率。由於光合作用對個體生長及生態系統運行至關重要，理解不同物種的光合作用與環境之間的關聯，成為植物逆境研究的關鍵。然而，傳統氣體交換測量方法繁瑣，難以快速獲取準確數據。本論文綜述葉綠素螢光技術的基礎概念及其在植物逆境生理研究中的應用，強調其高效、非破壞性及準確性的優勢，以提升光合作用監測的實務可行性。

Plants can modify their morphological structures, physiological metabolisms, and nutrient transports for survival under various abiotic stresses. The photosynthetic efficiency of plants plays a significant role in their life cycles and even has impact to the ecosystem. Therefore, understanding the relationship between the photosynthetic performance of different species and the environment is a fundamental key for the study of plant stress and eco-physiology. However, it is a problematic and cumbersome challenge for researchers to quickly and accurately obtain the real-time photosynthetic parameters by the use of a gas-exchange photosynthesis system. This paper reviews the fundamental principles of chlorophyll fluorescence technology and its use in plant stress physiology research, highlighting its benefits of high efficiency, non-destructiveness, and accuracy to improve the practical viability of photosynthesis monitoring.
