Photosystem II (PSII) functions were investigated in basil (Ocimum basilicum L.) plants sprayed with 1 mM salicylic acid (SA) under non-stress (NS) or mild drought-stress (MiDS) conditions. Under MiDS, SA-sprayed leaves retained significantly higher (+36%) chlorophyll content compared to NS, leaves. PSII efficiency NS conditions, evaluated at both low light (LL, 200 μmol photons m−2 s−1) and high (HL, 900 s−1), increased a parallel significant decrease the excitation pressure (1-qL) excess energy (EXC). This enhancement of conditions was induced by mechanism non-photochemical quenching (NPQ) that reduced singlet oxygen (1O2) production, as indicated quantum yield non-regulated loss (ΦNO). thylakoid structure water-sprayed appeared slightly dilated, declined, In contrast, did not change while functionality retained, similar HL. due photoprotective heat dissipation NPQ, which sufficient retain same percentage open reaction centers (qp), We suggest redox status plastoquinone pool (qp) MiDS HL initiated acclimation response leaves, electron transport rate (ETR) control plants.

Abstract Salt stress is a prevalent environmental issue that disrupts the redox balance and metabolic processes in plants, leading to reduced crop growth productivity. Currently, over 6.74 million hectares India are salt‐affected, about 75% of this land lies states major cultivators edible oilseed crops (rapeseed‐mustard). Therefore, study focused on efficacy glycine betaine (GB) supplementation mitigating detrimental effects salt Brassica juncea L. (Indian mustard) plants. Indian mustard plants were subjected [0, 50, 100, 150 mM sodium chloride] 20 days after sowing (DAS), while foliar spray GB was applied foliage at 50 70 DAS. The data showed substantially growth, photosynthetic rate, membrane stability, yield by significantly increasing lipid peroxidation, ion toxicity, cell death, electrolyte leakage, reactive oxygen species accumulation triggered oxidative stress. Supplementation with provided tolerance against salt‐induced toxicity since it increased biomass, water content, nutrient uptake, efficiency. Additionally, enhances osmolytes, antioxidant defence system, improves ionic balance, viability. Taken together, obtained provides deeper insights into beneficial effect exogenous application could have biotechnological uses enhance challenging environments.

Lagenaria siceraria is a nutritionally and medicinally important crop. Biostimulants offer sustainable alternative to agrochemicals, yet their effects on bottle gourd remain largely unexplored. This study was conducted over two consecutive seasons (2021 2022) under open-field conditions. The aim evaluate the impact of eco-friendly biostimulants—salicylic acid (SA), humic (HA), seaweed extract (SW)—on growth, yield, phytochemical composition (Lagenaria siceraria). A randomized complete block design with factorial arrangement implemented, including ten treatments three concentrations SA, HA, SW, alongside control. results demonstrated that these growth enhancers significantly improved plant parameters. application 1.2 g L−1 HA produced longest plants highest leaf flower number, while fruit traits such as length diameter were notably enhanced by 3 mL SW 0.8 SA treatments. Fruit seed dry weights also increased, 2 0.16 yielding heaviest fruits, treatment leading weight per fruit. Higher particularly resulted in significant increases total phenolic content, flavonoid antioxidant activity. Additionally, biostimulant influenced fixed oil content composition, variations fatty profiles. GC analysis identified 21 compounds, linoleic dominant acid, reaching its concentration 1 treatment. These findings highlight potential biostimulants enhancing productivity nutritional quality gourd, supporting adoption organic farming practices vegetable production.

Drought stress significantly limits crop productivity and poses a critical threat to global food security. Silica nanoparticles (SiO2NPs) have shown potential mitigate drought stress, but the role of nanostructure on overall efficacy remains unclear. This study evaluated solid (SSiO2NPs), porous (PSiO2NPs), hollow (HSiO2NPs) SiO2NPs for their effects drought-stressed tomatoes (Solanum lycopersicum L.). Silicic acid release rates followed order: HSiO2NPs > PSiO2NPs SSiO2NPs Bulk-SiO2. Compared untreated controls, foliar application under improved shoot Si concentrations plants' dry weight. These treatments also enhanced antioxidant enzyme activities (catalase, peroxidase, superoxide dismutase) phytohormone-targeted metabolome levels (jasmonic acid, salicylic auxin), contributing greater tolerance. Conversely, SSiO2NPs, silicic Bulk-SiO2 had minimal impact plant weight or physiological responses. results highlight importance architecture in alleviating promoting sustainable agriculture.
