“…The fluorescence rise during the first 2-3 ms is related to primary photochemistry and it has been suggested that stimulated L-and K-bands can be used as tools for evaluating potential to cope with (and recover from) drought stress (Oukarroum et al 2007). The L-band is influenced by the excitation energy transfer between PSII units, commonly denoted as connectivity or grouping (Strasser and Stirbet 1998).This can be influenced composition of PSII antennae that have been changed due to mutations or environmental conditions (Zivcak et al 2014a).…”

“…A DFI approach was used by Strauss et al (2006) to detect dark chilling tolerance in soybean genotypes. DFI has also been used to rank drought stress tolerance in 10 barley varieties (Oukarroum et al 2007) and 21 mutant germplasms of sesame (Boureima et al 2012). The most tolerant and the most sensitive races of barley and Sorghum bicolor from Egypt were identified using the PI parameter and the ChlF fast induction curve (Jedmowski et al 2013).…”

Plants living under natural conditions are exposed to many adverse factors that interfere with the photosynthetic process, leading to declines in growth, development, and yield. The recent development of Chlorophyll a fluorescence (ChlF) represents a potentially valuable new approach to study the photochemical efficiency of leaves. Specifically, the analysis of fluorescence signals provides detailed information on the status and function of Photosystem II (PSII) reaction centers, lightharvesting antenna complexes, and both the donor and acceptor sides of PSII. Here, we review the results of fast ChlF analyses of photosynthetic responses to environmental stresses, and discuss the potential scientific and practical applications of this innovative methodology. The recent availability of portable devices has significantly expanded the potential utilization of ChlF techniques, especially for the purposes of crop phenotyping and monitoring.

“…A sharp increase in basal level of chlorophyll fluorescence corresponding to photosynthetic inhibition is considered direct indication of inhibition of PSII electron transport under heat stress. Chlorophyll fluorescence measurement tool is of prime importance in quantifying the impact of drought and heat stress on plants [76]. Moreover, mitochondrial respiration is also considered important in determining the growth and survival of plants [77].…”

A brief review is given of investigations on stress-induced alterations in the yield of different biochemical contents in wheat. Wheat is major cereal crop for fulfilling the calories demands of growing population. Alterations in the worldwide climate are predicted to have critical sentence for crop production. Abiotic stresses such as heat and drought are major abiotic stresses restraining crop production. Heat stress reduces wheat growth by upsetting various physiological and biochemical processes and the developmental stage of the plant is critical in demonstrating the vulnerability of various species and cultivars subjected to high temperature. Heat stress did not affect the protein content but there is strong correlation between leaf nitrogen content and grain protein content. Induction of HSPs seems to be the universal response and adaptation to temperature stress. The synthesis of HSPs is believed to play significant role either in preventing or minimizing the adverse effects of high temperature both at molecular and cellular levels. Wheat has the tendency to adopt diverse types of responses to temperature stress as well as a heat shock by developing thermo-tolerance for the enhancement of the grain quality and yield.

“…Under water deficit, structural and functional alterations of photosynthetic apparatus can be estimated using the chlorophyll a fluorescence (CF) analysis (Stirbet and Govindjee, 2011;Zushi and Matsuzoe, 2017). The CF is a non-destructive, simple, and rapid testing method used to evaluate the functionality of the photosynthetic apparatus under environmental stress (Chen et al, 2015;Gonçalves et al, 2010;Oukarroum et al, 2007). Under water deficit, CF analysis has been used to monitoring and screening tolerance of species, genotypes and lineages to stress (Campos et al, 2014;Gomes et al, 2012;Oukarroum et al, 2009).…”

Drought stress is a major environmental factor limiting growth and agricultural productivity. The objective of this study was to compare photosynthetic responses to intense water deficit and the recovery capacity in crambe plants (Crambe abyssinica Hochst. cultivar FMS Brilhante and lineage FMS CR1101) using chlorophyll a fluorescence analyses. Plants were submitted to water deficit for seven days followed by rehydration. Chlorophyll a fluorescence measurements were performed using a Handy-PEA fluorometer. Under drought stress, there was a reduction of the leaf relative water content (RWC) and stomatal conductance (g s ), with full recovery after three days of rehydration to BRS Brilhante cultivar. Both genotypes showed decreased flux of electrons transport from the absorption to the reduction of the intersystem acceptors. FMS Brilhante cultivar showed better energetic connectivity (L-band) between photosystem II (PSII) units and lower inactivation of the oxygen-evolving complex (K-band), evidencing advantages of the cultivar compared to FMS CR1101 lineage. Finally, the recovery of photosynthetic activity observed in FMS CR1101 lineage during rehydration was due the phenomena related to the electron flow around the PSI.
