New 3-D Fluorescence Spectral Indices for Multiple Pigment Inversions of Plant Leaves via 3-D Fluorescence Spectra

open access: yesRemote Sensing
High-sensitivity fluorescence monitoring has been widely used in agriculture and environmental science. However, the active fluorescence detection information of leaf segments mainly focuses on total chlorophyll, and the fluorescence information of ...

Chlorophyll Fluorescence Imaging in Assessing Crop Abiotic Stress

open access: yes, 2023
Chlorophyll fluorescence imaging is a reliable, nondestructive tool that is ideally suited for plant eco-physiological research to monitor and quantify abiotic stress responses at the leaf or whole-plant level. This methodology solves the problem of sample heterogeneity and avoids potential errors that can occur with point measurements.

Imaging Spatial and Temporal Variation in Photosynthesis Using Chlorophyll Fluorescence

open access: yes
Chlorophyll fluorescence imaging provides a noninvasive rapid screen to assess the physiological status of a number of leaves or plants simultaneously. Although there are no standard protocols for chlorophyll fluorescence imaging, here we provide an example of routines for some of the typical measurements.
