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.

The paper presents the results of a study on effect various soil moisture supply conditions and increasing concentrations most common agricultural pollutants - cadmium (Cd) lead (Pb) growth Helianthus annuus L. 'Poseidon 625' seedlings. It was found that Cd absorption by seedlings under deficiency increases compared to sufficient watering conditions, while Pb decreases. determined simulating drought with an osmotic solution (7.4% sucrose) prevents aboveground part activates root system. shown influence in soil, development system 8-day-old is blocked, but active adventitious roots "goose foot" type observed, which contributes adsorption accumulation 2+ phytomass. maximum suppress both main sunflower simultaneously stimulate their above-ground part, probably indicates activation storage function stem, as next line defense from damaging effects combined stress.

The role of proline and betaine functionalized zinc oxide nanoparticles as drought stress regulators in Coriandrum sativum: an in vivo study

Discover Plants., Год журнала: 2024, Номер 1(1)

Drought stress poses a significant environmental challenge that substantially hinders plant growth and agricultural productivity on global scale. This disrupts water uptake, moderates photosynthetic efficiency, induces oxidative in plants, resulting considerable yield reductions. Recent advancements nanotechnology present promising approaches to enhance resilience against abiotic stresses. To study the influence of drought vegetative coriander plants its mitigation by zinc oxide nanoparticles (ZnO NPs) coupled with proline (ZnO-P) betaine (ZnO-B), pot experiment was designed. Plants were exposed treated 50 mg/kg 100 ZnO NPs, ZnO-P, ZnO-B NPs nanocomposites). watered wilting. It observed control pots irrigated 8–10 times while watering requirement reduced for 5–6 time when fertilized nanocomposites. Significant improvement parameters (length weight) under nanocomposites treatment. At ZnO-P shoot length increased up 71% root 24%. Shoot fresh weight improved (5 g 1.5 g, respectively) at NPs. The total phenolics flavonoid contents significantly decreased both roots shoots Ttotal antioxidant reducing power responses also remarkably variation inconsistent. free radical scavenging potential variable plants. Decrease super per dismutase activities (up 33% 32%, added findings demonstrate can be applying doped as fertilizer mitigate condition, strengthen stress, reduces crops save water. Future research could explore molecular mechanisms underlying these effects evaluate efficacy other crop species field conditions further validate their widespread use.

Heavy metal pollution poses a significant environmental challenge, adversely impacting global crop yields and posing health risks to humans. Cadmium (Cd), non-essential highly phytotoxic metal, substantial harm overall plant metabolism even at minimal concentrations. The current research aimed evaluate the beneficial impacts regarding priming of seeds trehalose upon development cells able photosynthesis traits, biochemical, physiological antioxidant defense systems among two variety maize (FH-1046 FH-5724) under Cd stress. For this purpose, pot experiment was carried out in University Education Lahore, Faisalabad campus. After weeks, growth parameters, biochemical concentration were examined. Results revealed that significantly reduced FH5427 showed better as compared with FH1046. Chlorophyll contents also decreased stress improved photosynthetic efficiency Carbohydrates protein ameliorated both varieties. Enzymatic non-enzymatic antioxidants greater lower treated group. This clearly alleviation potential plants. Trehalose inhibits movement into shoot from root system. growth, efficiency, characteristics cultivars. However, solution reduce impact Moreover, it enhances activity, enzymatic activities requisites superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) decreases reactive oxygen species. study suggests could be effectively utilized agricultural settings enhance tolerance cadmium
