Abstract Salinity has become a major environmental concern for agricultural lands, leading to decreased crop yields. Hence, plant biology experts aim genetically improve barley’s adaptation salinity stress by deeply studying the effects of salt and responses barley this stress. In context, our study aims explore variation in physiological biochemical five Tunisian spring genotypes during heading phase. Two treatments were induced using 100 mM NaCl (T1) 250 (T2) irrigation water. Significant phenotypic variations detected among response Plants exposed showed an important decline all studied parameters namely, gas exchange, ions concentration relative water content RWC. The observed decreases concentrations ranged from, approximately, 6.64% 40.76% K + , 5.91% 43.67% Na 14.12% 52.38% Ca 2+ 15.22% 38.48% Mg across different levels. However, under conditions, proline soluble sugars increased with average increase 1.6 times 1.4 concentration. Furthermore, MDA levels rose also genotypes, biggest rise Lemsi genotype (114.27% compared control). Ardhaoui Rihane higher photosynthetic activity other treatments. stepwise regression approach identified potassium content, /Na ratio, stomatal conductance SPAD measurement as predominant traits thousand kernel weight (R2 = 84.06), suggesting their significant role alleviating barley. Overall, at stage, accumulation irrigated soils saline significantly influences growth influencing exchange parameters, mineral composition genotype-dependent manner. These results will serve on elucidating genetic mechanisms underlying these facilitate targeted improvements barley's tolerance

Exogenous ascorbic acid as a potent regulator of antioxidants, osmo-protectants, and lipid peroxidation in pea under salt stress

BMC Plant Biology, Journal Year: 2024, Volume and Issue: 24(1)

Published: April 5, 2024

Abstract Pea ( Pisum sativum L.), a globally cultivated leguminous crop valued for its nutritional and economic significance, faces critical challenge of soil salinity, which significantly hampers growth production worldwide. A pot experiment was carried out in the Botanical Garden, The Islamia University Bahawalpur to alleviate negative impacts sodium chloride (NaCl) on pea through foliar application ascorbic acid (AsA). Two varieties Meteor (V1) Sarsabz (V2) were tested against i.e. 0 mM NaCl (Control) 100 NaCl. Three levels (Control), 5 10 applied spray. experimental design completely randomized (CRD) with three replicates. Salt stress resulted suppression growth, photosynthetic activity, yield attributes plants. However, AsA treatments effectively alleviated these inhibitory effects. Under conditions, treatment led substantial increase chlorophyll (41.1%), chl. b (56.1%), total contents (44.6%) carotenoids (58.4%). salt stress, there an Na + accumulation, lipid peroxidation, generation reactive oxygen species (ROS). increased proline (26.9%), endogenous (23.1%), soluble sugars (17.1%), phenolics (29.7%), enzymatic antioxidants SOD (22.3%), POD (34.1%) CAT (39%) both under stress. Salinity reduced while foliarly pod length (38.7%), number pods per plant (40%) seed weight (45.2%). To sum up, salt-induced damage plants by enhancing pigments, non-enzymatic activities, maintaining ion homeostasis, reducing excessive ROS accumulation limitation peroxidation. Overall, V2 (Sarsabz) performed better as compared V1 (Meteor).

Trade-Off Between Enzymatic Antioxidant Defense and Accumulation of Organic Metabolite Affects Salt Tolerance of White Clover Associated with Redox, Water, and Metabolic Homeostases

Plants, Journal Year: 2025, Volume and Issue: 14(2), P. 145 - 145

Published: Jan. 7, 2025

White clover (Trifolium repens) is an excellent perennial cold-season ground-cover plant for municipal landscaping and urban greening. It is, therefore, widely distributed utilized throughout the world. However, poor salt tolerance greatly limits its promotion application. This study aims to investigate difference in mechanism of relation osmotic adjustment, enzymatic nonenzymatic antioxidant defenses, organic metabolites remodeling between salt-tolerant PI237292 (Trp004) salt-sensitive Korla (KL). Results demonstrated that stress significantly induced chlorophyll loss, water imbalance, accumulations malondialdehyde (MDA), hydrogen peroxide (H2O2), superoxide anion (O2.-), resulting reduced cell membrane stability two types white clovers. Trp004 maintained higher leaf relative content as well lower potential oxidative damage, compared with KL under stress. Although exhibited activities dismutase, peroxidase, catalase, ascorbate monodehydroasorbate reductase, dehydroascorbate glutathione reductase than response stress, ascorbic acid (ASA), dehydroascorbic (DHA), (GSH), disulfide (GSSG), ASA/DHA, GSH/GSSG were detected Trp004. These findings indicated a trade-off relationship enzymes antioxidants different genotypes adapting In addition, accumulated more acids (glycolic acid, succinic fumaric malic linolenic cis-sinapic acid), amino (serine, l-allothreonine, 4-aminobutyric sugars (tagatose, fructose, glucoheptose, cellobiose, melezitose), other (myo-inositol, arabitol, galactinol, cellobiotol, stigmasterol) when they suffered from same concentration duration helped maintain energy supply, reactive oxygen species homeostasis, cellular metabolic homeostasis regard can be used resource cultivating salinized soils.

Salicylic Acid Seed Priming: A Key Frontier in Conferring Salt Stress Tolerance in Barley Seed Germination and Seedling Growth

Agronomy, Journal Year: 2025, Volume and Issue: 15(1), P. 154 - 154

Published: Jan. 10, 2025

The goal of the current study was to investigate effects seed priming with salicylic acid (SA) on germination parameters, seedling growth traits, nutritional element mobilization, and oxidative stress status in two barley species that were subjected various salt treatments. findings demonstrated salinity reduced a number parameters unprimed seeds impacted by impeding both species’ necessary nutrient mobilization. Under this abiotic stress, noticeable rise malondialdehyde electrolyte leakage also noted. Interestingly, pretreating SA improved performance under either 100 mM or 200 NaCl In fact, length dry weight stressed seedlings addition increasing rate mean daily germination. Additionally, increased content calcium, iron, magnesium, potassium while lowering concentrations sodium leakage. It is significant note that, comparison Hordeum maritimum, positive hormone more vulgare species.
