Green Synthesis of Nanoparticles Using Aqueous Leaves extract of Parkinsonia aculeata L. and Evaluation Their Resistance to Salt Stress of Some Aquatic Plants

الملخص

Salinity is one of the main abiotic factors that has an impact on a plant\\'s development and growth. The importance of biosynthesis silver nanoparticles from the Parkinsonia aculeata L. plant due to its unique physical and chemical properties and large surface area relative to its size. AgNPs were characterized using UV-Vis, FT-IR, XRD, SEM and TEM techniques , UV-Vis showed that the top absorption of AgNPs was at 420 nm wavelength, confirming the presence of silver nanoparticles , Use the FT-IR device to confirm the formation of AgNPs through bioactive functional groups and reaction sites found in the plant extract that were shown as a reduction agent to create AgNPs , And the XRD test showed that the AgNP size rate was 38.45nm , The FE-SEM showed that AgNPs were spherical in shape and size ranging from 30.21 nm to 64.03nm . In this study we used biosynthesis silver nanoparticles to help Cratophyllum demersum grow in the aquatic environment under salt stress conditions. It was used in 3 concentration (0.05, 0.1, 0.15 g) to understand its impact on the aquatic environment and the carrying of aquatic plants for salt stress. As a result of this study, the application of these nano-silver particles has improved the growth rate and the amount of chlorophyll and TOC and has made the properties of the aquatic environment move in a positive direction and also reduced the proline content. So, we conclude that AgNPs is a cheap and effective application for environmental treatment, especially water treatment.
