Effect of Foliar Application of Oligo-chitosan on physiological characteristics of Fragaria × ananassa under drought stress

Abstract

Background: There are many factors that affect plant growth and agricultural productivity, including soil salinity. There is evidence that chitosan (CTS) can increase plant growth and resilience to abiotic stress. However, it is still unclear if the software. Salt stress on Fragaria can be alleviated by the addition of exogenous CTS. Methods: Because of this,Exogenous CTS foliar application to Fragaria plants was studied in this study. In a sodium chloride solution of 100 mM. Exogenous CTS increased Fragaria growth, according to the study's findings.increases in leaf chlorophyll a, proline, and the dry weight of shoots and roots peroxide and catalase activities, as well as reduced membrane permeability. Result: Compared to untreated plants, lipid peroxidation in response to salt stress. In addition,The addition of exogenous CTS to Fragaria resulted in an increase in K+ accumulation, but this effect was not statistically significant. compared to plants treated with NaCl alone. Conclution The effect on the K+/Na+ ratio As a result of these findings,CTS may be able to counteract the negative effects of salt stress on plant growth and development, according to the research.biomass by altering intracellular ion concentration, osmotic control, and improving Fragaria leaf antioxidant enzyme activity.
