ABSTRACT
Silicon is the most aboundant element in soil and is beneficial for a large variety of plants. It is concentrated in plant tissues in quantities similar to that of macronutrients. Considerable damages to plants caused by abiotic stresses such as drought stress, salinity stress, heavy metal stress and nutrient imbalance, as well as biotic stresses like insect pests and pathogens and even herbivorous attacks, have been reported to be reduced significantly by silicon application. Soil contamination with toxic heavy metals (such as Cd ,Pb.As,Hg, Zn) is becoming a most devasting problem worldwide because of the rapid development of social economy. Silicon significantly improved the growth and biomass of crop plants and reduced the toxic effects of heavy metals after different stress periods. Si treatment ameliorated root function and structure compared with non-treated crop plants, which suffered severe root damage. Silicon plays a substantial role in alleviating heavy metal toxicity in crop plants. Also, silicon may reduce the toxic effects of heavy metals in soil. It may protect the foliage and increase light uptake and reduce respiration. Therefore, in this review, we discussed the effects of silicon on heavy metal stress in especially field crops.
Key words: Silicon, Heavy Metal, Field crops, Soil.
