An Introduction to Chlorophyll Fluorescence

2003
Photosynthesis is a physiological process that couples the energy of light to certain metabolic changes in biochemical reactions, via photochemical processes. Importantly, these metabolic changes would be endothermic in the absence of light, meaning that they would not proceed spontaneously.

Fluorescence-detected chlorophyll triplet states in chlorophyll-proteins

Journal of Molecular Structure, 1982
Abstract Chlorophyll (chl) occurs bound Co protein as discrete, well-defined complexes in photosynthetic membranes. Chlorophyll-proteins have been isolated from barley chloroplasts and chl triplet states observed at 4.2 K under continuous illumination using a fluorescence-detected zero field magnetic resonance technique.

Screening of mutants using chlorophyll fluorescence

Journal of Plant Research, 2021
Chlorophyll fluorescence has been widely used for the estimation of photosynthesis or its regulatory mechanisms. Chlorophyll fluorescence measurements are the methods with non-destructive nature and do not require contact between plant materials and fluorometers. Furthermore, the measuring process is very rapid.

Can chlorophyll-a fluorescence parameters be used as bio-indicators to distinguish between drought and salinity stress in Tilia cordata Mill?

Environmental and Experimental Botany, 2017
Chlorophyll-a fluorescence measurements have been used (for many years) to study the function and performance of photosynthetic machinery of various plants.

Chlorophyll a Fluorescence in Cyanobacteria: Relation to Photosynthesis

Cyanobacteria, 2019
In this chapter, we focus on the use of chlorophyll (Chl) a fluorescence to study various photosynthetic processes and their regulation in cyanobacteria. Compared to algae and plants, thylakoid membranes of cyanobacteria not only have photosynthetic, but

Chlorophyll fluorescence - A tool to assess photosynthetic performance and stress photophysiology in symbiotic marine invertebrates and seaplants.

Marine Pollution Bulletin, 2021
Chlorophyll a fluorescence is increasingly being used as a rapid, non-invasive, sensitive and convenient indicator of photosynthetic performance in marine autotrophs.

Effects of sodium hypochlorite treatment on the chlorophyll fluorescence in photosystem II of microalgae.

Science of the Total Environment, 2022
Chlorophyll fluorescence-based method shows great potentials for on-site assessing the vitality of algae in treated ship's ballast water. However, there is very limited information on the mechanism of chlorophyll fluorescence in photosystem II (PSII ...

Chlorophyll Fluorescence on the Fast Timescale

2018
Chlorophyll fluorescence is a rapid and non-invasive tool used for probing the activity of photosynthesis that can be used in vivo and in the field. It is highly relevant to the demands of high-throughput crop phenotyping and can be automated or manually applied.

Chlorophyll fluorescence biosensor for the detection of herbicides

Analytical and Bioanalytical Chemistry, 1994
A biosensor is described for the detection of triazine and phenylurea herbicides in drinking water by kinetic measurements of endogenous chlorophyll fluorescence in isolated chloroplasts from higher plants. The pocket-size device uses a diode laser for simultaneous excitation of sample and reference channels, and photodiodes for detection of the ...

Solar-induced chlorophyll fluorescence is non-linearly related to canopy photosynthesis in a temperate evergreen needleleaf forest during the fall transition

Remote Sensing of Environment, 2021
Solar-induced chlorophyll fluorescence (SIF) provides us with new opportunities to understand the physiological and structural dynamics of vegetation from leaf to global scales.
