Large parts of agricultural soil are contaminated with heavymetals by natural and anthropogenic activities. In plants, heavy metals hinder the normal metabolism by disturbing physiological and biochemical process (Ackova 2018). INTRODUCTION Metallic elements are intrinsic components of the environment.

Lead (Pb) is the second most toxic heavy metal after arsenic (As), which has no role in biological systems. Discover the world's research 19+ million members Upon entry into plants, HMs can alter normal growth and development by distorting nutrient balances, physiological and metalloenzyme activities, and damage cell ultrastructure.

Environmental Science and Pollution Research 2015 , 22 (18) , … the plant growth environment. In plants, heavy metals hinder the normal metabolism by disturbing physiological and biochemical process (Ackova 2018). Candidate genes associated with metal resistance in plants have been recently discovered and characterized. This research is supported by the Natural Research Council of Canada (NSERC). chemical fertilizers, the heavy metal mediated chemical toxicity has become one of the major environmental threats for the plants around the globe. pp 1-27 | Heavy metals reduce grain yields and dry weight of wheat plants, with Cadmium (Cd) having the highest effect and Chromium (Cr) the lowest.

Their toxicity must be considered in conjunction with that of the formulants already cited and of G, which can chelate such cations [64, 65]. They reduces productivity, bring stunting in growth and loss in chlorophyll (chlorosis) and protein contents in higher aquatic plants These metals are incorporated permanently in plants and then are passed on to animals and human beings.

Heavy metals (HMs) are described as elements with metallic properties having an atomic number higher than 20. The increased contaminants caused by anthropogenic activities in the environment and the importance of finding pathways to reduce pollution caused the silicon application to be considered an important detoxification agent.
