Nanoparticles play an important role in plant response to abiotic stresses including salt stress. In this study, the physiological and histological responses of CuO, ZnO, CaO nanoparticle (NP) applications on callus tissues developed from two alfalfa lines (Erzurum Muş) exposed (NaCl) stress were evaluated. The NPs synthesized extracts obtained healthy walnut shells using green synthesis approach then characterized by Scanning Electron Microscopy (SEM) X-ray diffraction analysis (XRD). leaf explants placed MS medium containing 4 mg L−1 2,4-D (2,4-dichlorophenoxyacetic acid), 50 mM NaCl, 0.8 ppm for 1 month dark. NP is determined be more effective than CuO ZnO induction explants. Malondialdehyde (MDA) content was higher treated with + NaCl compared other treatments. stage, without treatments, showed best results both H2O2 levels peroxidase (POX) activity NPs. highest protein rate stage formation after treatment CuO. LCSM displayed, under vitro conditions, that can greatly suppress negative effects calli samples. SEM supported laser scanning confocal microscopy (LSCM) analysis. Our findings suggest CaO, offer a simple method protect severity. Furthermore, these NPs, particularly hold potential broader application should evaluated various conditions beyond

Efficacy of Nano and Conventional Zinc and Silicon Fertilizers for Nutrient Use Efficiency and Yield Benefits in Maize Under Saline Field Conditions

Plants, Journal Year: 2025, Volume and Issue: 14(5), P. 673 - 673

Published: Feb. 22, 2025

The increasing severity of salinity stress, exacerbated by climate change, poses significant challenges to sustainable agriculture, particularly in salt-affected regions. Soil salinity, impacting approximately 20% irrigated lands, severely reduces crop productivity disrupting plants’ physiological and biochemical processes. This study evaluates the effectiveness zinc (Zn) silicon (Si) nanofertilizers improving maize (Zea mays L.) growth, nutrient uptake, yield under both saline non-saline field conditions. ZnO nanoparticles (NPs) were synthesized via co-precipitation method due its ability produce highly pure uniform particles, while sol–gel was chosen for SiO2 NPs ensure precise control over particle size enhanced surface activity. characterized using UV-Vis spectroscopy, XRD, SEM, TEM-EDX, confirming their crystalline nature, morphology, nanoscale (ZnO~12 nm, SiO2~15 nm). A split-plot experiment conducted assess effects nano conventional Zn Si fertilizers. applied at 10 ppm (22.5 kg/ha) 90 (201 kg/ha). Various agronomic, chemical, parameters then evaluated. results demonstrated that Zn/Si significantly cob length grain yield. Nano led highest biomass increase (110%) improved use efficiency 105% 110% conditions compared control. Under uptake efficiency, reduced sodium accumulation, increased 66% 106%, respectively, Principal Component Analysis (PCA) highlighted a strong correlation between applications with harvest index contents shoots, along other attributes. These findings highlight nanotechnology-based fertilizers can mitigate stress enhance productivity, providing promising strategy agriculture soils.
