Abstract
Pot experiments were performed to observe the response of Zinc oxide nano particles in heavy metals (chromium and arsenic) stress on two wheat varieties Aas 2011 and Faisalabad 2008 in comparison with two years 2019 and 2020. By using rooting medium, heavy metals (Cr and As 10ppm) were added to plants. After 14 days of germination, there were 10, 20, and 30 ppm formulations of ZnO nanoparticles applied for single heavy metal by foliar spray. Four replications were used in experiments that were completely randomized design. The amount of heavy metals in soils is gradually increasing, which has an impact on the ingredient's toxicity in various crop plants. Although zinc is a crucial mineral for plants, certain soils lack zinc or have low zinc bioavailability. Results specified the applications of ZnO-NPs, heavy metals including As and Cr concentration dropped through various morphological, physio-chemical, antioxidant enzyme activities and yield parameters along with the two varieties of wheat. Compared to Aas (2011), this drop was more prominent in Faisalabad (2008). Results also narrated that heavy metal (As) decreased various attributes of both wheat varieties. The findings indicated that ZnO nanoparticles used topically could improve the biochemical, morphological, antioxidant, and yield of heavy metal-stressed wheat varieties. The significance of ZnO-NPs in decreasing toxicity of heavy metals in wheat plants is thus supported by our findings.
