| dc.description.abstract | Abstract: The use of conservative products to improve growth and productivity of plants is as old as man. Zinc oxide nanoparticles (ZnONPs) use smart/controlled release and targeted delivery system to improve alot of parameters in plants including yield, thereby making them suitable as fertilizers. This study therefore assessed the effects of ZnONPs on the physiology, chlorophyll content, biochemical activities, antioxidant enzyme activities and bioaccumulation potential of Phaseolus vulgaris after 90 days of exposure to ZnONPs following standard methodologies. The growth parameters examined in this research revealed that there was significant increase at all evaluation times at P <0.05 in all ZnONPs treated plants. Furthermore, there was increase in yield especially at low concentration of 300 mg/kg for all the parameters examined. Flowers and fruits took longer to emerge at high doses of 600 and 1000mg/kg confirming the phytotoxicity tendencies of ZnONPs at higher concentration. Exposure of Phaseolus vulgaris to ZnONPs treatment increased productivity, promoted uptake and bioaccumulation of Zn in the leaf and roots tissues of Phaseolus vulgaris. Futhermore, ZnONPs enhanced the activities of antioxidant enzymes such as superoxide dismutase (SOD), ascorbate peroxidise (APX) and catalase (CAT). | |
