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
