Impact of Green Synthesised Silver Nanoparticles On In Vitro-Grown Lavandula Officinalis Plantlets

Abstract

Metal nanoparticles have been continuously used in many applications in nanotechnology. Silver nanoparticles are the most used ones amongst the other metal nanoparticles in nanobiotechnology. They have strong antiseptic, antibacterial, antifungal and antiviral effects depending on their sizes and shapes. Moreover, they are eco-friendly elements which have relatively low toxicity towards the environment and human. These nanoparticles can also be used in plant biotechnology applications. Our previous studies showed that green synthesized silver nanoparticles can be used safely and effectively as a surface sterilization agent for Lamiaceae seeds. In this study, in vitro-grown plantlets of Lavandula officinalis were subjected to green-synthesized silver nanoparticles at 1, 2 and 4 mg/L concentrations. Growth parameters such as elongation, shoot and root formation and biomass accumulations were investigated to understand the effects of silver nanoparticles on micropropagation of L. officinalis. The results showed that silver nanoparticles enhanced single shoot formations and average node length in L. officinalis node cultures. © 2020 by Nova Science Publishers, Inc. All rights reserved.
