Abstract
Marmordica charantia is a medicinal plant of the Cucurbitaceae family, which has antibacterial, anti-cancer, anti-tumor, and loweing effect for glucose, cholesterol and blood pressure. metallic nanoparticles like Zinc Oxide nanoparticles greatly affect on the physiological properties of plants, such as seed germination, plant growth and metabolism. Chitosan is a herbal source of carbon and helps the root system of plants to absorb more food from the soil and thus stimulate the growth and metabolism of the plant. Jasmonate is one of the most important natural growth regulators that play a special role in plant responses to environmental stress and is effective in increasing of secondary metabolites production. In this research, the effect of ZnO nanoparticles (20, 60 and 100 ppm), jasmonate (100, 250 and 500 μm) and chitosan (10, 50, and 100 μm) on growth, physiological and biochemical properties such as: photosynthetic pigments amount, total protein, total sugars, proline and secondary metabolites on Marmordica charantia were measured. The results of this study showed that different parameters such as phenolic compounds, flavonoids, antioxidant enzymes, carbohydrates, proline content, lipid peroxidation and photosynthetic pigments significantly were increased under the influence of silver nanoparticles, chitosan and jasmonate. The amount of secondary metabolites, such as phenol and flavonoids was significantly increased at high concentrations of all three of these elicitors. The highest increase in antioxidant enzymes except guaiacol peroxidase enzyme was significantly increased at high concentrations of Zno, chitosan and jasmonate. The highest carbohydrate content was observed at 100 μm chitosan and 500 μm jasmonate. The amount of proline was significantly increased in comparison with the control at 100 ppm Zno, 100 μm chitosan and 250 μm jasmonate. Generally the highest levels of secondary metabolites and antioxidant enzymes were observed at high concentrations of zinc oxide, chitosan and jasmonate oxide nanoparticles.
