暗-光转换过程中叶绿素a荧光诱导强度的快速变化反映了光合作用的各种反应,特别是电子传递反应。植物叶片中CFI瞬变的原位分析是对光合作用机构功能状态的一种敏感和非破坏性的分析。我们早些时候开发了一个用于分析CFI瞬变的图像仪器系统。该系统提供了关于整个叶片中不同光合作用活动的位置的信息,并可以识别环境胁迫造成的抑制位置。最近添加的扫描激光使我们能够在距离仪器较远的地方诊断植物的光合作用伤害。
Rapid changes in the intensity of chlorophyll a fluorescence induction (CFI) during dark-light transition reflect the various reactions of photosynthesis, especially of electron transport. The analysis of CFI transients in plant leaves in situ is a sensitive and non-destructive assay of the functional state of the photosynthetic apparatus. We earlier developed an image instrumentation system for analyzing CFI transients. The system gives information on the location of different photosynthetic activities in whole leaves in situ and can allow identification of sites of inhibition caused by environmental stresses. The recent addition of a scanning laser enables us to diagnose photosynthetic injuries to plants at a distance from the instruments.
