Abstract
Introduction: Ornamental plants grown growing in urban areas often face salinity stress. Methods: To evaluate the effects of foliar application of nano ZnO, Fe, and Se (zero and 2 g L-1) and NaCl salinity stress (0, 100, 200 mM) in on Gazania splendens L.; a factorial experiment was conducted based on ...

Introduction: Ornamental plants grown growing in urban areas often face salinity stress. Methods: To evaluate the effects of foliar application of nano ZnO, Fe, and Se (zero and 2 g L-1) and NaCl salinity stress (0, 100, 200 mM) in on Gazania splendens L.; a factorial experiment was conducted based on completely randomized designs was conducted in Research Greenhouse of Azarbaijan Shahid Madani University, Iran. Results and discussion: The results revealed that highest aerial parts dry weight, was recorded at no salinity and 100 mM NaCl salinity × nano Fe and ZnO foliar spray.The number of flowers (4) increased in under no salinity stress with+ ZnO and Fe foliar spraying and 100 mM salinity stress with + iron nanoparticle foliar sprayingapplication. The Na content, ion leakage, H2O2 content and malondialdehyde content were the highest recorded at NaCl 200 mM × no-foliar spray.Catalase activity was increased in NaCl 100 mM × nono Se and ZnO foliar application. Conclusion: The results showed that salinity had adverse effects on the studied traits of Gazania splendens L. However, Ffoliar spraying with ZnO and iron nanoparticles had a positive effect on increasing the enzymatic and non-enzymatic antioxidants activity compounds, and aerial parts dry weight in specially under 100 mM salinity stress, and it was found that the. Overall, Gazania plant is was able to withstand the salinity stress of 100 mM sodium chloride
