“…For example, F v /F m has been frequently used to evaluate the damage in PSII reaction centers of plants under severe stress (Sayed 2003). Values of F v /F m and F v '/F m ' are effective to indicate the point, at which plants suffer from a stress (Percival et al 2003, Faraloni et al 2011. To attain maximal photosynthetic efficiency and minimal photodamage, plants protect themselves by a dissipation of excess energy in chloroplasts through increasing NPQ in Chl fluorescence emission (Roháček and Barták 1999).…”

Soil water and salinity conditions of the riparian zones along the Tarim River, northwest China, have been undergoing alterations due to water use by human or climate change, which is expected to influence the riparian forest dominated by an old poplar, Populus euphratica. To evaluate the effects of such habitat alterations, we examined photosynthetic and growth performances of P. euphratica seedlings across experimental soil water and salinity gradients. Results indicated that seedlings were limited in their physiological performance, as evidenced by decreases in their height and biomass, and the maximal quantum yield of photosystem II (PSII) photochemistry (F v /F m ), the effective quantum-use efficiency of PSII (F v '/F m '), and photochemical quenching (q P ) under mild (18% soil water content, SWC; 18.3 g kg -1 soil salt content, SSC) and moderate (13% SWC, 22.5 g kg -1 SSC) water or salinity stress. However, seedlings had higher root/shoot ratio (R/S), increased nonphotochemical quenching (NPQ), and water-use efficiency (WUE) relative to control under such conditions. Under severe (8% SWC, 27.9 g kg -1 SSC) water or salinity stress, P. euphratica seedlings had only a fifth of biomass of those under control conditions. It was also associated with damaged PSII and decreases in WUE, the maximal net photosynthetic rate (P Nmax ), light-saturation point (LSP), and apparent quantum yield (α). Our results suggested that the soil conditions, where P.euphratica seedlings could grow normally, were higher than ~13% for SWC, and lower than ~22.5 g kg -1 for SSC, the values, within the seedlings could acclimate to water or salinity stress by adjusting their R/S ratio, improving WUE to limit water loss, and rising NPQ to dissipate excessive excitation energy. Once SWC was lower than 8% or SCC higher than ~28 g kg -1 , the seedlings suffered from the severe stress.

“…The fluorescent images captured can measure chlorotic or necrotic area and thus can separate healthy plant parts from senescent parts ( Hairmansis et al., 2014 ). Similar studies have been conducted in soybean ( Kim et al., 2014 ), sunflower ( Neto et al., 2011 ), acer ( Percival et al, 2003 ), and grape ( Dunlevy et al., 2022 ) for the development and optimization of salt tolerance screening protocol. However, steady state ChlF imaging cannot provide insight into the photosynthetic activity of plants, so kinetic ChlF has been introduced that can quantify the photosynthetic performance under stress condition.…”

Improper use of water resources in irrigation that contain a significant amount of salts, faulty agronomic practices such as improper fertilization, climate change etc. are gradually increasing soil salinity of arable lands across the globe. It is one of the major abiotic factors that inhibits overall plant growth through ionic imbalance, osmotic stress, oxidative stress, and reduced nutrient uptake. Plants have evolved with several adaptation strategies at morphological and molecular levels to withstand salinity stress. Among various approaches, harnessing the crop genetic variability across different genepools and developing salinity tolerant crop plants offer the most sustainable way of salt stress mitigation. Some important major genetic determinants controlling salinity tolerance have been uncovered using classical genetic approaches. However, its complex inheritance pattern makes breeding for salinity tolerance challenging. Subsequently, advances in sequence based breeding approaches and functional genomics have greatly assisted in underpinning novel genetic variants controlling salinity tolerance in plants at the whole genome level. This current review aims to shed light on physiological, biochemical, and molecular responses under salt stress, defense mechanisms of plants, underlying genetics of salt tolerance through bi-parental QTL mapping and Genome Wide Association Studies, and implication of Genomic Selection to breed salt tolerant lines.

“…Initial fluorescence F 0 increased in three taxa in response to increasing salinity, while F V /F M and PI P decreased in 5 genotypes. The authors explained the PI P parameter in the next publication ( Percival et al., 2003 ) as a calculation of RC/ABS × φ Po /(1 – φ Po ) × ψ o /(1 – ψ o ), thus it may be identified as PI ABS . The combined freezing × salt stress had a serious negative effect in all six genotypes.…”

Chlorophyll a fluorescence (ChF) signal analysis has become a widely used and rapid, non-invasive technique to study the photosynthetic process under stress conditions. It monitors plant responses to various environmental factors affecting plants under experimental and field conditions. Thus, it enables extensive research in ecology and benefits forestry, agriculture, horticulture, and arboriculture. Woody plants, especially trees, as organisms with a considerable life span, have a different life strategy than herbaceous plants and show more complex responses to stress. The range of changes in photosynthetic efficiency of trees depends on their age, ontogeny, species-specific characteristics, and acclimation ability. This review compiles the results of the most commonly used ChF techniques at the foliar scale. We describe the results of experimental studies to identify stress factors that affect photosynthetic efficiency and analyse the experience of assessing tree vigour in natural and human-modified environments. We discuss both the circumstances under which ChF can be successfully used to assess woody plant health and the ChF parameters that can be useful in field research. Finally, we summarise the advantages and limitations of the ChF method in research on trees, shrubs, and woody vines.
