This review is dedicated to David Walker (1928–2012), a pioneer in the field of photosynthesis and chlorophyll fluorescence. We begin this review by presenting the history of light emission studies, from the ancient times. Light emission from plants is of several kinds: prompt fluorescence (PF), delayed fluorescence (DF), thermoluminescence, and phosphorescence. In this article, we focus on PF and DF. Chlorophyll a fluorescence measurements have been used for more than 80 years to study… 

Dark drops of prompt chlorophyll fluorescence as a novel approach for evaluation of the photosynthetic machinery state

Analyzing the changes that occur in the photosynthetic machinery of plants is one of the most informative approaches for evaluation of the plant physiological state, their stress reactions,

The current status of chlorophyll fluorescence imaging is revised, in exploring photosynthetic features to evaluate the physiological response of plant organisms in different domains, to answer the question posed in the title.

On the polyphasic quenching kinetics of chlorophyll a fluorescence in algae after light pulses of variable length

Kinetics of the fluorescence decay in a suspension of the alga Scenedesmus quadricauda after actinic illumination give support for an earlier hypothesis on a double-hit three-state trapping mechanism in which the so-called semi-closed reaction centers of PSII are considered.

Variable chlorophyll fluorescence and its use for assessing physiological condition of plant photosynthetic apparatus

Analysis of plant behavior under diverse environmental conditions would be impossible without the methods for adequate assessment of the processes occurring in plants. The photosynthetic apparatus

Basic research is necessary to continue to provide us with an understanding of the molecular mechanism of the process and to guide us in reaching their goals of increasing food production and other chemicals the authors need for their lives.

Temperature Effects on Pea Plants Probed by Simultaneous Measurements of the Kinetics of Prompt Fluorescence, Delayed Fluorescence and Modulated 820 nm Reflection

The observation of a decrease in the amplitude of the DF curve and a change in its shape and in its decay is interpreted to suggest that heat treatment provokes an inhibition of electron donation by the oxygen evolving complex.

Effect of Light Intensity on Chlorophyll Fluorescence in Olive Plants – Application of mPEA Fluorometer

Light is one of the basic ecological physics factors, determining not only the possibility for plants existence but also the physiological state of their photosynthetic apparatus. Applying



Viewpoint: Avoiding common pitfalls of chlorophyll fluorescence analysis under field conditions.

Methodological advice is offered to delay use of automatically calculated fluorescence parameters, presented by the instrument software, until raw data 'traces' have been carefully inspected to ensure the integrity of findings.

This review examines how fluorescence parameters can be used to evaluate changes in photosystem II (PSII) photochemistry, linear electron flux, and CO(2) assimilation in vivo, and outlines the theoretical bases for the use of specificfluorescence parameters.

Chlorophyll fluorescence: New Instruments for Special Applications

During the past decade there has been remarkable progress in the understanding and practical use of chlorophyll fluorescence in plant science (1,2,3). This progress has resulted from fruitful

Chlorophyll a Fluorescence: A Bit of Basics and History

The goal is to bring to the readers the basics of Chl fluorescence, a bit of history, it's potential in understanding primary photophysical events (excitation energy transfer; charge separation), and secondary reactions (electron transport).

Time-Resolved Delayed Chlorophyll Fluorescence to Study the Influence of Bicarbonate on a Green Algae Mutant Photosystem II

Investigations On Photosystem II (Psii) Electron Transfer Processes by Observing Transient Absorption Changes Are Challenging. They Require High Psii Concentrations, Extended Averaging and are

Probing of photosynthetic reactions in four phytoplanktonic algae with a PEA fluorometer

High-resolution light-induced kinetics of chlorophyll fluorescence (OJIP transients) were recorded and analyzed in cultures of diatoms (Thalassiosira weissflogii, Chaetoceros mulleri) and

Delayed fluorescence in photosynthesis

This paper reviews historical data on DF research and recent advances in the understanding of the relation between the delayed fluorescence and specific reactions in PS II and an experimental method for simultaneous recording of the induction transients of prompt and delayed chlorophyllfluorescence and decay curves of DF in the millisecond time domain is discussed.


Abstract— The variable chlorophyll (Chl) a fluorescence yield is known to be related to the photochemical activity of photosystem II (PSII) of oxygen‐evolving organisms. The kinetics of the
