Salinity is one of major stresses which can severely limit plant production, especially in the arid and semi-arid regions. The present study was carried out to evaluate the impact of salinity stress on some physio-biochemical parameters in nitre bush plants (Nitraria schoberi). Thus, an experiment was carried out under natural conditions and salinity stress was induced by a combination of diffe...

determination of chlorophyll content and chlorophyll fluorescence has the potential needed to analyze the efficiency of photosynthesis in plants against environmental stresses, especially salinity, and its simplicity facilitates stress evaluation. in order to study the response of different photosynthetic characters to salinity stress at different sugar beet growth stages, two separate experime...

Mid- to high-latitude fjordic coastal environments experience naturally variable salinity regimes. Climate projections suggest that freshwater input into the coastal ocean will increase in the future, exposing coastal organisms to further periods of reduced salinity. This study investigated the effect of low salinity on Lithothamnion glaciale, a red coralline alga found in mid- to high-latitude...

Salinity is one of the most critical crises worldwide that ultimately compromises future food security. Brassinosteroids including brassinolide (BL) are a class polyhydroxy steroids phytohormones, play crucial role in several plant metabolic pathways and boost plants’ stress tolerance, but less data accessible on its function salt-affected grapevine. The experiment was conducted throughout 2019...

a study of physiological responses of different wheat cultivars to saline conditions can lead to an identification of the main mechanisms in salt tolerance. seven bread wheat cultivars differing in salt tolerance with varying ability of sodium accumulation in their different tissues were employed to assess ion distribution and sodium accumulation under saline conditions. ion distribution and na...

Effect of salinity on sprouting water uptake, ion uptake and metabolic efficiency of wheat seeds in the variety kanchan were studied in Jaydebpur. The treatments were 0, 4, 8, 12 and 16dS salinity level. The experiment was set in CRD with four replications. There were 50 seeds per petridish. Seeds were moistened with saline solution. Germination was recorded up to 72 hours with an interval of 1...

Plant growth and production are more severely inhibited by alkalinity than salinity. However, the metabolites responsible for reduced caused largely unknown. Here, Illumina RNA-Seq analysis targeted metabolome were used to identify differentially expressed genes responding salt alkali stresses. The expression levels of eight related photosynthesis some chlorophyll synthesis decreased under stre...

In the present study, effects of NaCl concentrations (0, 20, 40 and 80 mM) were investigated in Ceratophyllum demersum. Macronutrients N, P and K and micronutrients Zn and Cu were significantly decreased by NaCl salinity. In general, however, Fe and Mn accumulation showed to increase. As a results, NaCl toxicity disturbed the uptake and translocation of macro and micronutrients in the macrophyt...

Calcium enhances turfgrass response to salt stress. However, little is known about PSII photochemical changes when exogenous calcium was applied in salinity-stressed turfgrass. Here, we probe into the rearrangements of PSII electron transport and endogenous ion accumulation in tall fescue (Festuca arundinacea Schreber) treated with exogenous calcium under salt stress. Three-month-old seedlings ...

Salinity is an important environmental factor that limits plant growth and production. Grape is classified as salt sensitive plants. The object of this study was to evaluate effects of salinity on membrane lipid peroxidation, antioxidant components, and antioxidative enzymes activity in ten grape genotypes native to the regions around Urmia Salt Lake.Malondialdehyde content and protective enzym...
