Abstract This study was conducted to investigate the effects of salicylic acid and harvest date on yield biochemical physiological characteristics peanuts in different humidity conditions, which is novelty this research. For purpose, a split-plot factorial design during 2018 2019 cropping seasons based randomized complete block with three replications at experimental field Agricultural Natural Resources Research Education Center Guilan Province, Astara, Iran. Humidity regimes included rain-fed conditions (no irrigation), irrigation 10% flowering stage, pod formation stage +10% main plots, levels (100, 200, 300 µmol/l), dates (August 22, September 6, 21), were placed subplots.

The resilience of plants to concurrent abiotic stresses—such as drought, salinity, extreme temperatures, heavy metals, and elevated CO2 levels—is paramount in the era climate change. Reactive oxygen species (ROS), traditionally perceived mere byproducts metabolic processes, serve a dual role: crucial signaling molecules that facilitate plant adaptation deleterious agents causing cellular damage when excessively accumulated. In this review, we highlighted intricate equilibrium maintain through both enzymatic non-enzymatic antioxidant defenses mitigate ROS-mediated oxidative stress, emphasizing sophisticated strategies deploy counteract spectrum combined stresses. Some species, however, exhibit insufficient enhancement their intrinsic counterbalance stress-induced ROS accumulation consequent damage. Consequently, explored pivotal role diverse further strengthening defenses, offering profound insights into bolstering resilience. Furthermore, advent genetic engineering technologies unveils novel avenues for crop improvement, with strategic overexpression genes such SOD, APX, CAT, GPX, DHAR, GR, GST showing immense potential fortifying against challenges imposed by multiple Future perspectives entail deepening our understanding molecular mechanisms governing generation scavenging, investigating synergistic effects co-expressing genes, elucidating interactions between endogenous hormones exogenously applied molecules. We advocate integrative research methodologies, combining field experiments, controlled environmental studies, computational modeling, bridge gap laboratory discoveries practical agricultural applications.

In this study, effects mechanisms exogenous SA-triggered adaptation were investigated by detecting physiological biochemical indexes expression tolerance genes. The results showed that application could significantly increase antioxidant enzyme activities seedlings under stress, thereby reducing contents H2O2 MDA maintaining growth seedlings. Moreover, genes abiotic such as OsDREB2A, OsSAPK8, OsSAPK10 OsMYB2, up-regulated treatment, further enhance those like OsDREB2A suggesting might regulate activity via inducing enhancing rice. will enrich knowledge provide a reference for studying mechanism resistance rice, breeding new germplasm with improved resistance.

Nitric oxide (NO) is a gaseous free radical that acts as messenger for various plant phenomena corresponding to photomorphogenesis, fertilisation, flowering, germination, growth, and productivity. Recent developments have suggested the critical role of NO in inducing adaptive responses plants during salinity. minimises salinity-induced photosynthetic damage improves plant-water relation, nutrient uptake, stomatal conductance, electron transport, ROS antioxidant metabolism. contributes active participation ABA-mediated regulation. Similar crosstalk with other phytohormones such auxins (IAAs), gibberellins (GAs), cytokinins (CKs), ethylene (ET), salicylic acid (SA), strigolactones (SLs), brassinosteroids (BRs) were also observed. Additionally, we discuss interaction signalling molecules reactive oxygen species (ROS) sulphur (RSS). Conclusively, present review traces events NO-induced morpho-physiological adjustments under salt stress discusses how modulations upgrade resilience.

In this study, we collected seeds from five forb four graminoid common in European temperate forests. Seeds were germinated under glasshouse conditions subjected to moderate for 5 weeks. We assessed biomass partitioning, stomatal leaf morphology, gas exchange, minimum conductance ( g min ), chlorophyll fluorescence parameters. Comparison two ecological guilds revealed that graminoids had higher R/S, improved WUE, greater carboxylation efficiency, enhanced non‐photochemical quenching compared forbs. contrast, forbs significantly lower , with total area. Despite these differences morpho‐physiological functional traits, both groups experienced similar relative reduction after stress. Key predictors accumulation included photochemical quenching, area . A negative correlation between suggests plants residual water loss closure accumulate more Additionally, was positively correlated guard cell length, suggesting larger stomata contribute loss.
