Salicylic acid is known as a plant antitoxic. In this research, the effects of different concentration of lead acetate and Salicylic acid were studied on some growth factors of eggplant (Solanum melongena L.), which is one of the main agricultural plant in continents of Asia and Africa. For this purpose, different concentrations of lead acetate including 0.005, 0.01 and 0.015 m, salicylic acid including 1, 5 and 10 µm were spread on the experimental plants, and control group were spread with water. Results showed that treatment with lead acetate caused changes in growth factors and treatment with salicylic acid caused growth plant improvement, significantly. Results were significant for some growth factors including fresh and dry weight, leaf area, CGR, RLGR and LAR, but were not significant for NAR and LWR (P≤0.05).
