Fluorescence bands and chlorophyll a forms
Biochimica et Biophysica Acta (BBA) - Specialized Section on Biophysical Subjects, 1964 Abstract Fluorescence spectra were determined at temperatures between 20° and −196° for a number of photosynthetic organisms. Below −90° the single fluorescence maximum around 685 mμ was replaced by a system of three bands, at 686, 696 and 717–720 mμ in algal cells. Cooling usually resulted in a decrease of the 685-mμ band.

Investigations of chlorophyll interactions in Water Soluble Chlorophyll Binding Protein [PDF]
, 2016 Line narrowing spectroscopy was applied to water soluble chlorophyll binding protein (WSCP) containing only 2 chlorophylls. It was compared to natural occurring 4 chlorophyll WSCP.

Chlorophyll a + b Content and Chlorophyll Fluorescence in Avocado
Journal of Agricultural Science, 2012 Tonnage (T), Simmonds (S) avocado trees, and TxS crosses were evaluated for differences in chlorophyll content and maximal quantum yield of photosystem II in sun and shade-type leaves. Total chlorophyll content by area (Chl a+bar) ranged from 984 mg m -2 in TxS240 to 4320 mg m -2 in Simmonds.

Application of chlorophyll fluorescence in fruit science [PDF]
1st PhotosynthOS Conference - Book of abstracts, 2023 The wide range of research on chlorophyll fluorescence (ChlF) demonstrates its usefulness in many plant biology, agronomy, and ecology research areas. Perennial fruit trees are frequently exposed to various biotic and abiotic stresses throughout their lifespan, limiting their crop quality and yield.

An algorithm for computing chlorophyll-a concentrations using a dual-frequency fluorosensor [PDF]
An algorithm to be used on data from a dual-frequency fluorosensor (i.e. one using two wavelengths for excitation of chlorophyll-a fluorescence) to compute total chlorophyll-a concentration and to partition that chlorophyll between two color groups ...

Changes in microphytobenthos fluorescence over a tidal cycle: implications for sampling designs [PDF]
, 2013 Intertidal microphytobenthos (MPB) are important primary producers and provide food for herbivores in soft sediments and on rocky shores. Methods of measuring MPB biomass that do not depend on the time of collection relative to the time of day or tidal ...
