Abstract
In Pakistan, wheat is a major staple crop that is also considered as energy crop. At present, it has been developed as animal fodder, malt goods and human consumption. Under the heavy metal stress, the growth and net production of wheat is compromised. Arsenic and Chromium are known as the utmost injurious heavy metal to different cereal crops that affect their physiological and yield attributes. In roots, high quantities of heavy metals are particularly necessary for fodder, herbal crops and cereals. In most recent years, Zinc oxide nanoparticles are known as active entities that are commercially used to enhance the growth, development and production of wheat crop to get economic benefits under stresses. However, in Pakistan, Zinc oxide nanoparticles interaction in Wheat. For this purpose, pot experiments were performed to evaluate the response of Zinc oxide nano particles under heavy metals (chromium and arsenic) stress on two wheat varieties (Aas 2011 and Faisalabad 2008) during 2018-20. Heavy metals (Cr and As 10ppm) were added to plants as rooting medium before sowing. After 14 days of germination, 10, 20, and 30 ppm of ZnO nanoparticles were applied one time as foliar spray. Four replications were used in these experiments using completely randomized design (CRD). Results indicated that the applications of ZnO-NPs, reduced the effect heavy metals including As and Cr concentration in relation to various morphological, physio-chemical, antioxidant enzyme activities and yield parameters in two varieties of wheat. Compared to Aas (2011), variety Faisalabad (2008) showed better performance for these attributes. Results also narrated that heavy metal (As) decreased various attributes of morphology, physiology and yield of both wheat varieties. These findings indicated that the use of ZnO nanoparticles can improve the biochemical, morphological, antioxidant and yield of wheat varieties under heavy metal stress. Applications of ZnO-NPs also showed significance in lowering the toxicity of heavy metals from
