Nickel (Ni) contaminated soil is a persistent risk to plant growth and production worldwide. Therefore, explore the Ni toxicity levels in sweetpotato areas, we investigated influence of different treatments (0, 7.5, 15, 30, 60 mg L -1 ) for 15 days on phenotype, uptake, relative water content, gas exchange, photosynthetic pigments, oxidative stress, osmolytes, antioxidants, enzymes plants. The results presented that at higher (30 substantially reduced growth, biomass, root morphological traits. Pearson correlation analysis suggested causes injuries as augmentation hydrogen peroxide (H 2 O malonaldehyde (MDA) RWC, pigment. Furthermore, this study revealed could tolerate moderate treatment (up by reducing stress. also indicated increase activities mentioned not sufficient overcome toxicity. Based these results, suggest using low Ni-contaminated better be used phytoremediator soil.

Abstract The growth of wheat ( Triticum aestivum ) is constrained by soil salinity, although some fungal species have been shown to enhance production in saline environments. yield grain crops affected salt stress, and this study aimed investigate how arbuscular mycorrhizal fungus (AMF) mitigates stress. An experiment was conducted assess the impact AMF on conditions 200 mM Wheat seeds were coated with at a rate 0.1 g (10 8 spores) during sowing. results demonstrated that inoculation led significant improvement attributes wheat, including root shoot length, fresh dry weight shoot. Furthermore, increase chlorophyll a, b, total, carotenoids observed S2 treatment, validating effectiveness enhancing under stress conditions. Additionally, application reduced negative effects salinity increasing uptake micronutrients such as Zn, Fe, Cu, Mn while regulating Na (decrease) K (increase) In conclusion, confirms successful strategy for reducing yield. However, further investigations are recommended field level different cereal establish more effective amendment alleviation wheat.

Over the years, changes in agriculture industry have been inevitable, considering need to feed growing population. As world population continues grow, food security has become challenged. Resources such as arable land and freshwater scarce due quick urbanization developing countries anthropologic activities; expanding agricultural production areas is not an option. Environmental climatic factors drought, heat, salt stresses pose serious threats worldwide. Therefore, utilize remaining water effectively efficiently maximize yield support increasing demand crucial. It essential develop climate-resilient crops that will outperform traditional under any abiotic stress conditions salt, well these combinations. This review provides a glimpse of how plant breeding evolved overcome harsh environmental what future would be like.

Abiotic stress causes extensive loss to agricultural yield production worldwide. Salt is one of them crucial factor which leads decreased the through detrimental effect on growth and development crops. In our study, we examined a defense substance, salicylic acid (SA 1 mM) mature vegetative (60 Days after sowing) flowering (80 DAS) stage Pusa Sadabahar (PS) variety Capsicum annuum L. plants gown under different concentrations NaCl (25, 50, 75, 100 150 maintained in identical sets pots during whole experiment. Physiological studies indicated that increase root & shoot length, fresh dry weight, number branches per plant, (number fruits plant) salt + SA treatment. Biochemical studies, enzymatic antioxidants like CAT, POX, non-enzymatic antioxidant such as ascorbic (AsA content), carotenoids, phenolics, besides other compounds proline, protein, chlorophyll contents were studied at 10 days treatment stage. The addition led lowering general, all parameters but increased same stage, especially presence NaCl; although control I (without NaCl) remained lower value than II (with SA, without NaCl). Interestingly, total phenolics higher or whereas chlorophylls treatments with NaCl. Thus, physiological concentration (1 appears be significantly effective against addition, however, proline accumulates treated sets, help developing NaCl-induced drought tolerance.

Crop productivity is enormously exposed to different environmental stresses, among which chromium (Cr) stress raises considerable concerns and causes a serious threat plant growth. This study explored the toxic effect of Cr on sweet potato plants. Plants were hydroponically grown, treatments 0, 25, 50, 100, 200 µM applied for seven days. exhibited that low level treatment (25 µM) enhanced growth, biomass, photosynthesis, osmolytes, antioxidants, enzyme activities. However, significant deleterious effects in photosynthetic attributes, enzymes observed at higher levels treatment. The remarkable reduction growth traits was associated with over-accumulation H2O2 MDA contents (410% 577%, respectively) under highest rate (200 µM). Under Cr, uptake roots 27.4 mg kg-1 DW, while shoots 11 DW translocation from root shoot 0.40. results showed accumulation negatively correlated phenotypic physiological parameters. It may be proposed toxicity oxidative damage as sustained by augmented lipid peroxidation, reactive oxygen species, reduced rate, chlorophyll, stomatal traits. chloroplastic ultrastructure damaged, more apparent size levels. Furthermore, aggregated concentration positively correlates increase osmolytes superoxide dismutase (SOD) activity leaves potato. Moreover, improved SOD do not help protect against high stress. Overall, these findings will improve understanding defense mechanisms

Salinity is one of the most concerning ecological restrictions influencing plant growth, which poses a devastating threat to global agriculture. Surplus quantities ROS generated under stress conditions have negative effects on plants’ growth and survival by damaging cellular components, including nucleic acids, lipids, proteins carbohydrates. However, low levels are also necessary because their role as signalling molecules in various development-related pathways. Plants possess sophisticated antioxidant systems for scavenging well regulating protect cells from damage. Proline such crucial non-enzymatic osmolyte machinery that functions reduction stress. There has been extensive research improving tolerance, effectiveness, protection plants against stress, date, substances used mitigate adverse salt. In present study Zinc (Zn) was applied elucidate its effect proline metabolism stress-responsive mechanisms proso millet. The results our indicate impact development with increasing treatments NaCl. doses exogenous Zn proved beneficial mitigating NaCl morphological biochemical features. salt-treated plants, (1 mg/L, 2 mg/L) rescued salt (150mM) evidenced increase shoot length (SL) 7.26% 25.5%, root (RL) 21.84% 39.07% membrane stability index (MSI) 132.57% 151.58% respectively.The content improved at all concentrations maximum 66.65% mg/L Zn.
