Abstract
The study aims to investigate the
phytostimulatory effects of zinc oxide and copper oxide nanoparticles
biosynthesized using cow dung extract by analysing the effect of different
concentrations of cow dung extract (200 ppm, 100 ppm, 50 ppm), ZnSO4 solution (200 ppm, 100 ppm, 50 ppm), ZnONPs (200 ppm,
100 ppm, 50 ppm), CuONPs (200 ppm, 100 ppm, 50 ppm) and CuSO4
solution (200 ppm, 100 ppm, 50 ppm) on different germination and plant
development parameters in okra. The results show retardation in seed germination
in presence of all the treatments. Furthermore, seedling shoot length and root
length was found to be increased in plants exposed to both the nanoparticles
(ZnONPs and CuONPs), however, the effect was much higher than their metallic
counterparts (ZnSO4 solution and CuSO4 solution) as well as cowdung extract. Furthermore, the
plants exposed to green nanoparticles (ZnONPs and CuONPs) showed higher fresh
weight as well as dry weight in comparison to plants exposed to ZnSO4 solution, CuSO4 solution and cow dung extract. On the contrary, plants
exposed to ZnSO4 solution, CuSO4 solution and cow dung extract showed lesser dry weight
in comparison to control, while, nanoparticle exposed plants showed high dry
weight.
