Low-Cost Chlorophyll Fluorescence Imaging for Stress Detection. [PDF]
Sensors (Basel), 2021 Plants naturally contain high levels of the stress-responsive fluorophore chlorophyll. Chlorophyll fluorescence imaging (CFI) is a powerful tool to measure photosynthetic efficiency in plants and provides the ability to detect damage from a range of biotic and abiotic stresses before visible symptoms occur.

Chlorophyll Fluorescence Imaging for Environmental Stress Diagnosis in Crops. [PDF]
Sensors (Basel)The field of plant phenotype is used to analyze the shape and physiological characteristics of crops in multiple dimensions. Imaging, using non-destructive optical characteristics of plants, analyzes growth characteristics through spectral data. Among these, fluorescence imaging technology is a method of evaluating the physiological characteristics of ...

On the Importance of Non-Gaussianity in Chlorophyll Fluorescence Imaging
Remote Sensing, 2023 We propose a mathematical study of the statistics of chlorophyll fluorescence indices. While most of the literature assumes Gaussian distributions for these indices, we demonstrate their fundamental non-Gaussian nature. Indeed, while the noise in the raw fluorescence images can be assumed as Gaussian additive, the deterministic ratio between them ...

Quantitative imaging of chlorophyll fluorescence [PDF]
New Phytologist, 1995 summaryA computer‐controlled video system is described where images of chlorophyll fluorescence from oat (Arena saliva L.) leaves are captured throughout an induction curve. The fluorescence parameters φ11 and ΔFm/F'm which represent photosystem II photochemical efficiency and non‐photochemical quenching respectively are calculated from images taken ...

Phenotyping Plant Responses to Biotic Stress by Chlorophyll Fluorescence Imaging. [PDF]
Front Plant Sci, 2019 Photosynthesis is a pivotal process in plant physiology, and its regulation plays an important role in plant defense against biotic stress. Interactions with pathogens and pests often cause alterations in the metabolism of sugars and sink/source relationships.
