ABSTRACT: The aim of this study was to investigate to determine different concentrations of cadmium (Cd) on germination parameters and physiological effects in early developmental stage of tomato plant (Solanum lycopersicum Lam.). Cd concentrations were organized as Control (0 ppm Cd), Cd5 (5 ppm Cd), Cd10 (10 ppm Cd), Cd20 (20 ppm Cd) and Cd40 (40 ppm Cd). For this purpose, 10 tomato seeds were germinated in petri plates with bi-layered filter paper. Germinating rate and Vigor Index were determined. Tomato seedlings were cultured in hydroponic Hoagland’s medium to explore physiological parameters such as length, fresh and dry weights and relative water content (RWC). Additionally, the effects of Cd on pigment and total protein contents of tomato seedlings were measured at the end of the experimental stage. 20 and 40 ppm applications of Cd resulted with significant decrease in germination rate compared to Control. Additionally, Cd concentrations caused significantly decrease in Vigor Index according to Control plants. Significant decreases in length, fresh and dry weight and RWC in shoot of Cd treated tomato seedlings were determined compared to Control. Root tissue was negatively affected from Cd treatments. Fluctuated results were determined for pigment and protein contents. As a conclusion, tomato seedlings were negatively affected from Cd stress.
