Abstract
Eco-friendly natural nano-compounds, including biological extracts from Aspergillus niger, Azadirachta indica, and Moringa oleifera are known for their efficacy. Silver nanoparticles (AgNPs) improve seed germination, plant growth, and photosynthetic efficiency. This study focuses on how bio-silver may affect the development and physiology of Capsicum annuum L., specifically bio-silver nano priming with different quantities of synthesised nanoparticles. Nano priming improved seed germination (90-100%), seedling length (53%), seedling weight (75%), seedling vigour index (65%), as well as germination speed and index. The phytochemicals significantly increased chlorophyll (6-145%), carotenoids (19-138%), TPC (12- 74%), and TFC (7-80%), all of which support plant growth. Nano priming also enhanced TAA (7– 67%) and FRAP (7–57%). The total protein content (18-111%) increased, promoting enzyme activity and plant development. Nano-priming increased ROS generation in seedlings more than the control and other priming treatments. This indicates that both ROS, including SOD (2-36%) and POD (2-72%), play crucial roles in seedling growth. The various mechanisms involved in nano priming-induced ROS/antioxidant systems in seedlings, such as the production of proline content (7-154%) and the decrease in MDA (1-15%), all contribute to the regulation of nanoparticle-generated stress.
