Abstract: (139 Views)
Moringa oleifera, is a medicinal, fast-growing and perennial plant that grows in almost all tropical and subtropical regions and can tolerate a vast range of rainfall conditions. This survey was carried out as a factorial on a completely randomized design, in order to investigate the impact of foliar spraying of Cu nanoparticles (0, 5, 10 and 20 ppm) on the physiological traits and the content of phytochemical compounds of Moringa plants under sodium chloride salinity (0, 3.9, 7.8 and 11.7 dS/m). Based on the findings, ion leakage was enhanced under salinity stress, and treatment via nano-Cu reduced the parameter. Thus, the highest (75.01%) and the lowest (38.62%) ion leakage were recorded at the highest salinity level without nanoparticle application and the control treatment (without salinity stress and no nanoparticle application), respectively. The results illustrated an improvement in the anthocyanin, phenol, flavonoid and antioxidant activity of moringa leaves under salt-treated plants and nano-Cu. Therefore, the highest content of anthocyanin (4.68 µmol/g FW), phenol (16.02 mg of gallic acid/g FW), flavonoid (0.83 mg quercetin/g FW), and antioxidant activity (86.71 μg/ml) were obtained under 11.7 dS/m of salinity and 20 ppm of nano-Cu. A phytochemical investigation of leaf extract compounds indicated that salinity declined Caffeic acid and chlorogenic acid, while foliar spraying with nano-Cu enhanced them. Hence, the highest amount of caffeic acid was recorded at different levels of nano-Cu under no salt treatment and the lowest amount (1.09 mg/L) at the highest level of salinity without applying nano-Cu. In addition, the highest amount of chlorogenic acid (22.5 mg/L) was observed under no-salt treatment with the application of 20 ppm of nano-Cu and the lowest amount (2.6 mg/liter) at 7.8 dS/m Salt without the presence of nano-Cu. In general, nano-Cu improved the tolerance of Moringa to salt stress by boosting the compounds involved in the biosynthesis of antioxidants and other physiological traits, as well as the secondary metabolites of the plant.
