Priming agents combat copper stress in wheat (Triticum aestivum L.) under hydroponic conditions: Insights in impacts on morpho–physio–biochemical traits and health risk assessment

Ecotoxicology and Environmental Safety, Journal Year: 2025, Volume and Issue: 291, P. 117899 - 117899

Published: Feb. 1, 2025

In recent years, the use of priming agents, such as silicon, melatonin, salicylic acid, glycine betaine, and ascorbic acid has gained significant attention for their role in mitigating abiotic stresses across various plant species. While previous research been conducted on individual impact metal stress resistance among crop species, combined effects context heavy stressed conditions remain underexplored. Wheat (Triticum aestivum L.) seedlings was grown under toxic concentration copper (Cu) i.e., 100 µM which were applied with hydroponic 21 days. The outcomes indicated that Cu nutrient solution notably reduced growth biomass, photosynthetic pigments, gas exchange attributes. However, also induced oxidative plants by increasing malondialdehyde (MDA), hydrogen peroxide (H2O2) increased compounds enzymatic non-enzymatic antioxidants, health risk index (HRI) gene expression sugar content. Furthermore, a increase proline metabolism, AsA-GSH cycle, pigmentation cellular components observed. Although, application different showed characteristics, compounds, decreased HRI. addition, agents enhanced fractionation metabolism cycle T. seedlings. These results open new insights sustainable agriculture practices hold immense promise addressing pressing challenges contamination agricultural soils.

Analysis of Plant Growth and Flower Aromatic Composition in Chinese Rosa rugosa Cultivars Under Cadmium Stress

Horticulturae, Journal Year: 2025, Volume and Issue: 11(2), P. 214 - 214

Published: Feb. 17, 2025

Rosa rugosa is an excellent aromatic plant species valued for both essential oil extraction and ornamental applications. This study aimed to evaluate its adaptive responses, bioaccumulation capacity, production quality under cadmium (Cd) stress, providing insights phytoremediation sustainable agriculture. A controlled pot experiment was conducted using two cultivars (R. ‘Zizhi’ bud mutation R. ‘Baizizhi’) subjected various Cd treatments. Growth parameters physiological indices, such as antioxidant enzyme activities, chlorophyll content, photosynthesis rates, floral volatile organic compounds, were systematically analyzed. concentrations ranging from 5 50 mg·kg−1 maintained growth, but significantly elevated activities (SOD + 65.94–300.53%, POD 37.58–75.06%, CAT 12.48–12.62%) content (+20.27–242.79%). In contrast, 400 severely inhibited inducing chlorosis leaf desiccation. Total volatiles showed a hormetic response, peaking at 200 (+46.08%). Sesquiterpenoids greater Cd-responsiveness than monoterpenoids, though core profiles remained stable. The exhibited root bioconcentration BAF > 0.1 limited translocation TF < 1, indicating phytostabilization potential. Despite tolerance up mg·kg−1, field application recommended below mg·kg−1—a threshold exceeding China’s soil limits (GB 15618-2018). These findings position it dual-purpose crop ecological restoration fragrance in Cd-impacted areas.

Physiological Adaptations of Vigna radiata to Heavy Metal Stress: Soluble Sugar Accumulation and Biomass Enhancement

Plants, Journal Year: 2025, Volume and Issue: 14(8), P. 1191 - 1191

Published: April 11, 2025

Background: Heavy metal contamination significantly threatens crop growth and global food security. Understanding plant responses to such stress is crucial developing stress-tolerant crops. This study explores the physiological biochemical of Vigna radiata (L.) R. Wilczek mercury, lead, copper stress, focusing on role soluble sugar accumulation biomass enhancement in conferring heavy tolerance. Methods: Commercially available V. seeds were exposed varying concentrations (50, 150, 300 mg/L) mercurous nitrate, lead chloride under controlled conditions. The germination rates, seedling growth, parameters as protein content analyzed using spectrophotometry statistical methods, including ANOVA. Results: results demonstrated that ion increased dry weight, while all tested metals promoted accumulation. Although inhibited at higher concentrations, exhibited strong tolerance moderate levels. Conclusion: highlights adaptive strategies radiata, soluble-sugar-mediated osmotic adjustment enhanced allocation, which contribute its resilience stress. These findings provide insights for breeding stress-resistant crops managing heavy-metal-contaminated environments.
