Role of Zinc on Pesticides-Induced Oxidative Damage and Seed Germination on Brassica Species in-Vitro
Journal Title: IJAR-Indian Journal of Applied Research - Year 2015, Vol 5, Issue 1
Abstract
Use of pesticides in agriculture is important to ensure crop viability but when used indiscriminately, these can lead to destruction of crops. The present research focuses on the risk of chlorpyrifos on germination and oxidant status of rye seeds and effect of zinc under such conditions. Seeds in control group were normal water treated. 2 μm zinc (ZnSO4.6H2O) was given to the seeds and 1% chlorphyrifos was given. The results showed tha t zinc and chlorpyrifos are not exerting toxicity as indicated by the seed germination. Chlorpyrifos caused an increase in phenolic content but significant increase in glutathione levels and catalase activity was found to be increased in rye seeds. However when zinc was administered alongwith chlorpyrifos, zinc exerts a toxic effect, thus producing free radicals which led to oxidative stress. It can be concluded that risk to the seeds may occur through indirect damage by oxidative stress.
