چکیده	Silicon (Si) has not been considered as an essential element for growth and development of higher plants, it has been proved to be beneficial for the healthy growth and development of many plant species, and plants usually deposited this element in their cell walls. Boron (B) toxicity is an important disorder that can limit plant growth on soils of arid and semiarid environments throughout the world. High concentrations of boron may occur naturally in the soil or in the ground water. In this research, role of Si in change of catalase enzyme activity and total Protein content of extracts of leaves investigated under boron toxicity. The experiment was arranged as a factorial scheme based on completely randomized design (CRD) with three replications in greenhouse condition. Three levels of B (0.5, 2, 4 mg L-1) from H3BO3 and three levels of Si (0, 28, 56 mg L-1) from Na2SiO3 were added to nutrient solution. Results of the present study indicated that silicon addition significantly increased catalase activity and total soluble protein content in sweet corn plants. In conclusion, silicon can improved boron toxicity effects in sweet corn.
