Synthesis of cinnamic acid nanocomposite and investigation of its effects on root osmolality compounds and phytochemical parameters of peppermint (Mentha piperita L.) plant under salt stress

The present study was conducted to synthesize a cinnamic acid nanocomposite and better understand its behavior in salinity control in peppermint plants. For this purpose, three factors, salinity stress with different concentrations of sodium chloride, including ۰, ۵۰, ۱۰۰, and ۱۵۰ mg/liter; cinnamic acid with a concentration of ۵۰ μM; and cinnamic acid nanocomposite based on carboxymethyl cellulose with a concentration of ۵۰ μM were considered. The results showed that with increasing salinity levels, the content of soluble compounds (۳۰.۵۵% proline and ۳۶.۲% glycine betaine) and phytochemical parameters (۶.۵۱ to ۱۰۸.۳%) increased. The application of cinnamic acid and its nanocomposite increased these vital parameters significantly. There was a ۷ to ۲۷.۰۱% increase in soluble compounds and a ۲۷.۹ to ۱۷۴.۳% increase in phytochemical parameters. As a biostimulant, the nanocomposite significantly increased peppermint tolerance under salinity conditions. Cinnamic acid and nanocomposite containing it acted as a plant growth regulator in saline conditions. The results showed that nanocomposite is more effective than cinnamic acid in improving biochemical and phytochemical parameters. The reason for this is the high solubility, better and faster absorption and transfer of nanocomposite compared to the material itself. This material and the nanocomposite containing it showed an innovative path in research that can successfully improve the performance of plants to cope with salinity.
