Background: Wheat, an important cereal crop, is commonly cultivated in arid and semiarid areas, therefore, it often experiences water deficit conditions. The consequences of induced stress on wheat can be mitigated through vermicompost amendments. To address drought seedlings, a pot experiment was conducted the wire-house which two contrasting cultivars, Faisalabad-08 (drought-tolerant) Galaxy-13 (drought-sensitive), were exposed to three level conditions: well-watered [D0, 70% field capacity (FC)], moderate (D1, 45% FC), severe (D2, 30% FC). Four rates vermicompost, derived from cow dung enriched with cellulolytic microbes, applied (VT0, control; VT1, 4 t ha–1; VT2, 6 VT3, 8 ha–1) experiment. Data various physiological, biochemical, enzymatic antioxidants recorded. Results: Our results demonstrated that treatments significantly reduced nutrient accumulation, chlorophyll SPAD values, carotenoid content both cultivars where maximum reduction recorded for stress. Nonetheless, application improved these traits, statistically contents, value, total contents observed VT1 under treatments. While lowest untreated replicated pots. Among exhibited greater resistance drought, as evidenced by higher values aforementioned traits compared Galaxy-13. Soil-applied also showed positive influence antioxidant enzyme activities grown well water-scarce Conclusions: findings this study revealed conditions substantially decreased physiological biochemical attributes crop. However, soil-applied particularly at optimum rate, had impact seedlings Moving forward, exploring potential utilizing microbe-enriched stands promising avenue mitigate detrimental effects wheat. Further research direction could offer substantial insights into enhancing resilience productivity

Results showed exogenous supplementation significantly improved attributes such as, shoot root length, fresh dry weight, ratio (RSR), relative content (RWC) while decreasing electrolyte leakage (EL). Furthermore, positive effect chlorophyll a, b, a/b total (TCC), carotenoids (CC), soluble protein (SPC), sugars (SSC), proline (TPC), catalase (CAT), ascorbate peroxidase (APX) observed. at 2mM yielded highest values these variables.

Water stress can adversely affect seed germination and plant growth. Seed osmopriming is a pre-sowing treatment in which seeds are soaked osmotic solutions to undergo the first stage of prior radicle protrusion. enhances performance under stressful environmental conditions, making it an effective method improve resistance yield. This study analyzed effect with polyethylene glycol (PEG) on physiological parameters Coronilla varia L. Priming treatments using 10% 30% PEG enhanced percentage, vigor, index, vitality seedling mass reduced time reach 50% (T50). The concentration that led better results was 10%. content soluble proteins (SP), proline (Pro), sugars (SS), malondialdehyde (MDA) seedlings increased severity water stress. In addition, stress, electrolyte leakage rose, peroxidase (POD) superoxide dismutase (SOD) activities intensified, while catalase (CAT) activity at mild-to-moderate but declined more severe deficiency. priming significantly improved (T50) Across gradient here tested (8 12% PEG), SP content, Pro SOD compared unprimed treatments. Under PEG-induced primed displayed lower MDA than their counterparts exhibited higher CAT POD activities. However, differences leakage, activity, between were not significant.

Rice (Oryza sativa ) faces challenges to yield and quality due urbanisation, deforestation climate change, which has exacerbated high night temperature (HNT). This review explores the impacts of HNT on physiological, molecular agronomic aspects rice growth. Rise in minimum threatens a potential 41% reduction by 2100. disrupts growth stages, causing reduced seed germination, biomass, spikelet sterility poor grain development. Recent findings indicate 4.4% decline for every 1°C increase beyond 27°C, with japonica ecotypes exhibiting higher sensitivity than indica. We examine relationships between elevated CO2 , nitrogen regimes HNT, showing that complexity balancing positive effects biomass challenges. Nitrogen enrichment proves crucial during vegetative stage but causes disruption reproductive affecting starch synthesis. Additionally, we elucidate impact plant respiration, emphasising mitochondrial photorespiration antioxidant responses. Genomic techniques, including CRISPR-Cas9, offer manipulating genes tolerance. Plant hormones carbohydrate enzymatic activities are explored, revealing their intricate roles fertility, size metabolism under HNT. Gaps understanding genetic factors influencing heat tolerance trade-offs associated hormone applications remain. The importance interdisciplinary collaboration is needed provide holistic approach.
