Maize (Zea mays L.), an important crop used for animal feed and human consumption, is currently threatened by water shortage. Recently, the usage of nanomaterials has attracted worldwide attention due to their applications in various fields. This research aimed evaluate comparative efficacy different metal oxide nanoparticles mitigating drought stress maize. Iron oxide, manganese copper were biosynthesized from leaf extract Conocarpus erectus L. characterized via UV-Vis, XRD, FTIR, SEM. The synthesized initially optimized at concentrations (0, 25, 50, 75, 100 ppm). doses each nanoparticle then applied maize plants under levels (50% FC, 75% 100% FC). Compared control, application significantly improved growth parameters 30% 50% 27% 26% FC. chlorophyll content also 35%, 32%, 29% as compared respectively. antioxidants (CAT, POD, SOD, APX) 37%, 34%, 31%, Moreover, use resulted a significant decrease cellular oxidative (MDA, H2O2) 23% 50%FC, Biosynthesized FeO NPs, MnO Cu NPs have demonstrated potential maize, suggesting promising approach enhance performance water-limited conditions. Further recommended explore long-term impacts practical these findings sustainable agriculture.

Melatonin Promotes Yield Increase in Wheat by Regulating Its Antioxidant System and Growth Under Drought Stress

Biology, Год журнала: 2025, Номер 14(1), С. 94 - 94

Drought stress constitutes a major challenge to wheat production. Melatonin plays vital role in plants’ resistance drought stress. Nevertheless, the influence of melatonin seed coating on ability remains unclear. Hence, this study, (Yunmai 112) was chosen as experimental material. The research results indicated that 100 µM exogenous treatment enhanced germination rate seeds by 11% compared CK group. (100 or 200 µM) significantly inhibited accumulation ROS seedlings under conditions and facilitated growth seedlings. Then, elevated activity antioxidant enzymes (CAT, Cu/Zn-SOD, POD, T-GSH) strengthened In contrast control, raised contents soluble protein chlorophyll Further studies demonstrated promoted increase thousand-grain weight yield Taking together, is an effective approach for enhancing

ABSTRACT Climate change poses a global challenge to agricultural production and food security, especially in developing countries. In Northeast China, major grain‐producing region, the Maize–Soybean rotation is crucial for sustainable development. However, previous studies have mainly focused on single crops lacked attention soil health regional scale analysis. This study utilises APSIM model predict crop yields organic carbon (SOC) under two Representative Concentration Pathways 4.5 8.5 (RCP4.5 RCP8.5) future climate scenarios different latitude regions of China. The result shows that has significant spatial temporal variations yield storage system. Compared baseline (1980–2010), maize from −11.6 42.8 kg 10a −1 (RCP4.5) 7.1 39.8 (RCP8.5), soybean vary −13.1 3.9 −16.2 −5.6 (RCP8.5). SOC increases slowly 0 20 cm decreases 40 cm, resulting decrease 21–334 ha 26–280 (RCP8.5) predicted storage. PLS‐PM results show precipitation negative impact accumulation, temperature rise RCP8.5 scenario positively correlated with yields, correlation stronger RCP8.5, which higher explanation changes. significantly affects stocks system Northeastern during extreme weather. Therefore, adaptation strategies should fit local needs, early‐maturing opt drought‐resistant, early varieties employ conservation tillage water‐saving methods, while medium late‐maturing areas select late varieties, adjust sowing enhance fertiliser efficiency.
