The integration of nanoparticles (NPs) into agriculture is altering traditional methods, enhancing productivity and sustainability. This study explores the application iron oxide (FeONPs) to mitigate salt-alkaline stress in cherry tomatoes. We investigated FeONPs at three concentrations (FeONP25, FeONP50, FeONP100 mg/kg soil) pot experiments under non-stress (NS) (SAS) conditions. SAS conditions decreased biomass nutrients untreated plants, a trend reversed by FeONPs. treatments significantly boosted pigment levels SAS, thereby increasing chlorophyll (10.65–43.05%), b (7.19–41.33%), total (9.84–42.49%), carotenoids (8.97–36.09%) compared control. also reduced NPQ stress, indicating enhanced photosynthetic efficiency. Oxidative markers (H2O2, O₂−, MDA) were strongly induced control plants but declined with treatments. Antioxidants osmoregulatory substances improved FeONPs, demonstrating their potential alleviate tomato plants.

Iris typhifolia Kitag is a perennial herbaceous species with high ornamental and applied value. Elucidating the mechanism of saline–alkali tolerance in crucial for their promotion areas. Saline–alkali stress one factors that affects plant growth, which has become significant global issue. In this study, we measured physiological biochemical indexes I. typhifolia, through germination potting trials, to evaluate resistance different levels artificial (0, 50, 100, 150, 200 mmol·L−1). The results showed negatively impacted parameters, cell membrane integrity, photosynthetic parameters. Different trends osmoregulatory substances endogenous hormones were observed. It was shown had potential adaptability environment by enhancing its internal defense mechanism. Based on regression analyses, threshold calculated be 87.15 mmol·L−1, provided theoretical basis application soil saline–alkalization

Exogenous melatonin (MT) regulates plant growth and mitigates stress in response to stress. To analyze the machinery of exogenous melatonin, which improves salt alkaline tolerance oats, MT’s function was identified oat seed germination stage our previous study. In this study, morphogenesis, photosynthetic physiology, hormone levels, ion homeostasis were evaluated using same MT treatment concentration. The results revealed that compared S45 treatment, 100 μmol·L−1 efficiently increased seedling height main root length seedlings; promoted secondary development; enhanced volume surface area; maintained a higher pigment content (carotenoids; chlorophyll a; b); raised leaf rate (Pn), intercellular CO2 concentration (Ci), conductance H2O (Gs), transpiration (Tr); light energy absorption conversion leaves; GA3, Tryptamine (TAM), IAA contents; decreased ABA levels. Hierarchical cluster analysis also contents P, K, Ca, Mn, Cu, Mg, Fe, Zn, Mo, Cd, Al, Se, Ni, Co, Ti; Na/K ratio; cellular ionic seedlings under saline–alkali stress, as with untreated group. These findings showed adaptation through regulating physiological process growth. This suggests plays different role improving stages oat.

Saline and alkaline stress is one of the major abiotic stresses facing agricultural production, which severely inhibits growth yield plant. The application plant regulators can effectively prevent crop reduction caused by saline stress. Exogenous melatonin (MT) act as a signaling molecule involved in regulation variety physiological processes plants, has been found to play key role enhancing improvement tolerance stresses. However, effects exogenous MT on table grape seedlings its mechanism have not clarified. aim this study was investigate morphological (Vitis vinifera L.) under results showed that resulted yellowing wilting leaves decrease chlorophyll content, whereas alleviated degradation seedling promoted accumulation soluble sugars proline content. In addition, increased activity antioxidant enzymes, scavenging reactive oxygen species (ROS) generated conclusion, stress, enhanced resistance promote development industry areas.

Salt stress can affect various physiological processes in plants, ultimately hindering their growth and development. Melatonin (MT) effectively resist multiple abiotic stresses, improving plant resistance. To analyze the mechanism of exogenous MT to enhance salt tolerance red clover, we conducted a comprehensive study examine influence on parameters, including seed germination indices, seedling morphological traits, photosynthetic indicators, using four distinct clover varieties (H1, H2, H3, H4). This investigation was performed under conditions with differing pH values, specifically utilizing NaCl, Na2SO4, NaHCO3, Na2CO3 as stressors. The results showed that solution immersion significantly improved indicators seeds stress. foliar spraying 50 μM 25 increased SOD activity (21–127%), POD activity, soluble sugar content, proline content (22–117%), chlorophyll (2–66%), net rate. It reduced MDA (14–55%) intercellular CO2 concentration seedlings Gray correlation analysis Mantel test further verified is key factor enhancing stress; most significant improvement observed for NaHCO3 demonstrated improve through variety mechanisms, an increase antioxidant enzyme osmoregulation ability, cell membrane stability. Additionally, it improves efficiency architecture, promoting energy production, growth, optimal resource allocation. These mechanisms function synergistically, enabling sustain normal development

Salt stress is one of the principal abiotic stresses limiting agricultural production and seriously inhibiting seed germination rates. This study selected salt-tolerant rice variety HD961 salt-sensitive 9311 as experimental materials to investigate physiological metabolic effects exogenous Spd priming on seeds seedlings under NaCl stress. The experiment involved treating with 0.1 mmol·L−1 then subjecting them 100 for 24 h, sampling analysis at h four-leaf-one-heart stage. results indicated that stress, rice’s vigor indices significantly decreased. However, reduced accumulation malondialdehyde, enhanced capacity osmotic adjustment, increased amylase antioxidant activity by 50.07% 26.26%, respectively. Under morphological development was markedly inhibited, whereas improved aboveground belowground biomass conditions, well content photosynthetic pigments. It also damage from electrical conductivity, helped maintain ionic balance, promoted excretion Na+ Cl− absorption K+ Ca2+. In 9311, soluble protein 15.12% compared HD961, especially when effect more pronounced. summary, these findings might provide new research perspectives strategies improving salt tolerance

Agaricus bisporus is a globally important edible fungus. The occurrence of ginger blotch caused by Pseudomonas 'gingeri' during A. growth and post-harvest stages results in significant economic losses. biotoxin monoacetylphloroglucinol (MAPG) produced P. responsible for inducing on bisporus. However, the understanding toxic mechanisms MAPG remains limited, which hinders precise control disease breeding disease-resistant varieties.
