Chlorophyll fluorescence—a practical guide [PDF]
Journal of Experimental Botany, 2000 Chlorophyll fluorescence analysis has become one of the most powerful and widely used techniques available to plant physiologists and ecophysiologists. This review aims to provide an introduction for the novice into the methodology and applications of chlorophyll fluorescence. After a brief introduction into the theoretical background of the technique,

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 ...

CHLOROPHYLL a FLUORESCENCE ANALYSIS IN FORESTS
Annali di Botanica, 2016 A European-wide assessment of chlorophyll a fluorescence (ChlF, prompt fluorescence on dark-adapted samples) parameters in forest ecosystems was carried out in the years 2012-2013, within the 7FP FunDivEUROPE project. A total of 1596 trees growing in 209 stands distributed in six countries, from Mediterranean to boreal sites, were sampled.

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.

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.

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.

Fluorescence Decay Studies of Chlorophyll a in Vivo
Biophysical Journal, 1965 The study of the fluorescence of chlorophyll a offers a useful approach toward better understanding of the primary act of photosynthesis. This paper describes new measurements of the decay of chlorophyll a fluorescence in vivo, made with a considerably improved oscilloscopic-display technique.

Environment Control in Biology, 2009 Chlorophyll fluorescence imaging is useful as a non-destructive method for evaluating photosynthetic function of plants. A dynamic change in chlorophyll fluorescence intensity, known as the chlorophyll fluorescence induction phenomenon, can be observed by illuminating a dark-adapted green leaf with a stable intensity excitation light.

Measurement of the Fluorescence Lifetime of Chlorophyll a In Vivo
Biophysical Journal, 1969 New measurements have been made of fluorescence lifetime (tau) of chlorophyll a in the algae Chlorella pyrenoidosa, Porphyridium cruentum, Anacystis nidulans, and in spinach chloroplast. tau-values of 0.6 and 0.7 nsec were obtained with green plants. Anacystis and Porphyridium gave a tau of 0.5 nsec.
