Abstract:
Silicon has been considered as a beneficial detoxification agent, since due to anthropogenic activities in the environment, there have been increased contaminants. It also has an impact on the sustainability of agricultural production. In this regard, Si plays a major role in amelioration of stresses imposed by both biotic and abiotic factors, for example extreme amount of heavy metal in plants. There are different systems of silicon intercession in plants, which incorporate decrease of heavy metal take-up, change in pH of soil, silicon substantial metal development that works by chemical and physical pathways. Silicon is known to be useful in moderating aluminium, manganese, cadmium and substantial metal toxicity and furthermore, saltiness or salinity, drought, freezing and chilling stress. The important function of Si in decreasing the abiotic stress includes: Chelation and stimulation of antioxidant system in plants, restriction in movement of toxic metal ions in growth media, root to shoot translocation, co-precipitation of complex formation of heavy toxic metal ions with silicon, uptake processes, changes in structure of plant. In any case, these components are related with plant species, genotype of the plant, metal components, conditions for development and the time of stress imposed to plants. Exogenous silicon use has been archived to build substantial metal resistance in plants.
