“…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).

“…Positive L-band and K-band values in barley (Hordeum vulgare L.), passion (Passiflora edulis L.) and in two maize (Zea mays L., cvs. Shaandan 609 and Zhengdan 958) cultivars differing in drought tolerance were described (Gomes et al, 2012;Oukarroum et al, 2007;Zhang et al, 2015), revealing decreased function of oxygen evolving complex (OEC), and decreased energetic connectivity between PSII units. The authors observed that after rewatering, signals of recovery occurred, which were attributed to an increase in drought resistance or hardening.…”

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.

“…These studies demonstrate that drought-tolerant and drought-sensitive cultivars can be differentiated at the level of PSII. An increase of ABS/RC ratio under drought stress has also been observed (Van Heerden et al 2007;Gomes et al 2012), possibly due to inactivation of some PSII RCs or an increase in antenna size.…”

Chlorophyll a fluorescence as a tool to monitor physiological status of plants under abiotic stress conditions

et al. 2016

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.

Abstract:The purpose of this study was to explore influence of abiotic factors, such as high temperature, water deficiency and high solar radiation on the photomembrane of grapevine leaves. Grapevine leaves were collected from variety Rkatsiteli (Vitis vinifera) and placed at a temperature of +45 °C and +55 °C for 5 min, respectively. The relative volume of water in leaves was gradually reduced to 50%, and then leaves were irradiated with 6,000 µmol/m 2 ·s of white light. Changes provoked by stressful abiotic factors were determined using rapid and delayed chlorophyll fluorescence methods. It was shown that value of variable component of chlorophyll fluorescence (Fv), intensity of electron transport between the photosystems (ETR), intensity of expended electrons in carboxylation (ETRn) and oxygenation (ETRp) and index of non-photochemical quenching (NPQ), allow studying molecular mechanisms of the impact of abiotic factors and the resulting damage degree. Based on delayed and rapid fluorescence data, it was demonstrated that temperature of +45 °C adversely affects oxygen production system and CO 2 assimilation mechanisms, while at +55 °C, the ETR decreases. Reduction of relative water volume in leaves up to 50%-55% leads to sharp reduction in ETR and inhibition of photosynthesis. In case of irradiation of leaves with high-intensity light of 6,000 µmol/m 2 ·s, NPQ of light falling on a leaf increases, thus protecting photosynthesis apparatus from damage.
