Invigouration treatment of metal and metal oxide nanoparticles for improving the seed quality of aged chilli seeds (Capsicum annum L.)

In the present study, inorganic bulk and nano nutrients of zinc oxide, titanium oxide, and silver nanoparticles were synthesized using the chemical reduction method and invigourated with chilli seeds cv. PKM 1 each at 750, 1000 and 1250 mg kg−1 by using template-free aqueous solution. After nanoparticles invigouration, the seeds were analyzed for various parameters such as germination (%), shoot length, root length, and seedling vigour. Other important parameters, such as electrical conductivity and antioxidant enzyme activity (catalase and lipid peroxidase), were also analyzed, which in turn reflected the enhancement of seed quality of chilli seeds when they were invigourated with ZnO, TiO2 and silver nanoparticles. The results indicated that the chilli seeds invigourated with ZnO nanoparticles at 1000 mg kg−1 enhanced the germination and seedling vigour in aged seeds.
