Green Synthesis of Nanoparticles Using Aqueous Leaves Extract of Capparis spinosa L. and Evaluation of their Resistance to Salt Stress of some Aquatic Plants

Abstract

Salinity is one of the major biological stressors that has an impact on the growth and development of plants. Because of AgNPs distinct physical and chemical characteristics as well as their huge surface area in relation to their size. Green synthesized of AgNPs was used to reduce the salt stress aquatic plant Ceratophyllum demersum. AgNPs were biosynthesized by Capparis spinosa L. extract and characterized using UV-Vis, FT-IR, XRD, SEM and TEM techniques which gave spherical shape of crystal size 44.33 nm. Three concentrations of AgNPs were prepared (0.05, 0.1 and 0.15 g) and used to study the salt stress. The effect on the properties of the aquatic environment was carried out at four weeks for salt pressure. As a result, the study showed that these particles improved the properties of the aquatic environment by reducing the amount of dissolved salt ions. In addition, the growth rate of the C. demersum plant increased, the amount of chlorophyll and the total organic carbon content increased and the proline content decreased So, we conclude from this study that AgNPs is a useful, ecofriendly and interesting application for use in environmental treatments, especially in water treatment.
