TL;DR: Chlorophyll fluorescence parameters based on the lake model q(L), phi (NPQ) and phi(NO) have been found more appropriate for estimating the fraction of open centres, the quantum yield of regulated energy dissipation in photosystem II (PSII) and the Quantum yield of non-regulated energy dissolution in PSII, respectively.

Journal ArticleDOI
TL;DR: In this article, the effect of two nutrient solution temperatures (cold (10°C) and warm (22°C)) during two flowering events of rose plants ( Rosa Â× hybrida cv. Grand Gala) were examined by measuring chlorophyll (Chl) a fluorescence, ammonium (NH 4 + ) content and nitrate reductase (NR) activity in four different leaf types, that is, external and internal leaves of bent shoots and lower and upper leaves of flowering stems.

Journal ArticleDOI
TL;DR: This work found out how the photosynthetic light reaction, measured by chlorophyll a fluorescence in internal and external leaves of arched shoot could be modulated by light changes, and measured nitrate reductase activity, NH4+, sucrose and starch levels.

Journal ArticleDOI
TL;DR: Results related to Chl a fluorescence, indicate that pruned plants have a higher capacity for better promoting the photosynthetic light reaction than non-pruned plants.

Journal ArticleDOI
TL;DR: This review distills the historical and current developments spanning the last several decades of SIF heritage and complementarity within the broader field of fluorescence science, the maturation of physiological and radiative transfer modelling, SIF signal retrieval strategies, techniques for field and airborne sensing, advances in satellite-based systems, and applications of these capabilities in evaluation of photosynthesis and stress effects.

Journal ArticleDOI
TL;DR: The increased rate of photorespiration in plants during the onset of drought stress can be seen as an acclimation process to avoid an over-excitation of PSII under more severe drought conditions.

Journal ArticleDOI
TL;DR: An overview of the application of chlorophyll fluorescence in horticultural research is provided, highlighting how CFI can be used for these purposes and in which subjects it can be applied in the future.

Journal ArticleDOI
TL;DR: In this paper, the effects of different light intensities on chlorophyll fluorescence characteristics and yield in lettuce were investigated, and an optimal regulation strategy of light intensity that can maximize economic benefits for lettuce growers in some regions of the world is proposed.

TL;DR: In this paper, the authors summarize the knowledge of chlorophyll fluorescence induction, starting from basic theory through parameters and useful experimental protocols and results up to special kinds of application.
Abstract: Field crops are frequently exposed to drought and high temperature in the field. As the stress tolerance is the major target of many research and breeding programmes, the efficient and reliable tools and methods useful in screening of the heat and drought stress effects are required. The techniques based on measurement of chlorophyll fluorescence induction belong recently to fundamentals of plant stress research; however, in most cases the very basic tools are used and its potential is not utilised sufficiently. This proposed chapter tries to summarise the knowledge, starting from basic theory through parameters and useful experimental protocols and results up to special kinds of application of chlorophyll fluorescence techniques. In addition to generally used pulse-amplitude-modulated (PAM) method with saturation pulse analysis, the fast fluorescence kinetics, the fluorescence imaging, as well as simultaneous measurements of chlorophyll fluorescence with other parameters and their potential application in drought and heat-stress research are discussed.
