RESUMO
Trachyspermum ammi L. commonly known as Ajwain is an annual herb belonging to the family Apiaceae. It is enormously grown in Egypt, Iran, Pakistan, Afghanistan, and India as well as European region. Seeds of Ajwain were highly administered by traditional healers and usually employed for different ailments. Nanomaterials are known to have plant growth promoting effects, which could find applications in agriculture. In this study, the nanoparticles (NPs) showed the potential to enhance the primary metabolites when administered during germination. Therefore, nanoparticles elicitation can be used to increase the productivity, nutritional values and metabolite contents in Trachyspermum ammi L. This study aimed to provide new insight of the potential growth promoting effects of the nanoparticles () on plant system. Different concentrations of two nanoparticles, that is, iron pyrite (FeS2) and molybdenum disulphide (MoS2) at three different concentrations of 25ug/ml, 50ug/ml and 75ug/ml were tested on the seeds of Trachyspermum ammi L. The data indicated that nanoparticles enhanced the seedling growth as greener leafs and increased lengths of epicotyl and hypocotyls were seen. These nanoparticles also showed the potential to increase the contents of primary metabolites during germination and the total soluble protein content in seed was increased in nanoparticles-treated seeds as compared to control. The total protein profiling by SDS-PAGE indicated significant differences in number and molecular weights of protein bands upon exposure to nanoparticles.
