Abstract:

Heavy metal is one of the main aspects that limit plant growth. Mercury is one of the most hazardous heavy metals because it is absorbed by plant roots and then moves to the leaves and other parts of the plant. Based on this critical subject, a complete randomized design (CRD) with factorial arrangement-controlled experiment was carried out on "producing Mercury stress tolerance in maize by foliar spray of Nano silicon". In this experiment, we employ four treatments of Nano silicon with T1=0.03g/L, T2=0.06g/L, T3=0.09g/L, and T4=0.12g/L, and a single stress treatment of Mercury chloride at a concentration of 0.02g/L. T1 is kept under control in both régimes. The results of this experiment showed that it slows plant growth in terms of morphological characteristics as shoot, stem and leaf length and width. In term of physiological attributes, rate of photosynthesis, transpiration and other factors decline. By applying Nano silicon treatments, it improves these attributes as increased morphological attributes such as shoot length which is maximum 58cm, leaf length 43cm stem width and other factors. It will increaseanatomical, biochemical, antioxidants, chlorophyll contents and antioxidant characters. The Nano silicone particles increase the different attributes of the Maize plant. .
