The aim of the study was to evaluate the applicability of the Gompertz equation to describe the process of germination of tomato seeds (Lycopersicon esculentum cv. Promyk). Germination tests were carried out at five temperatures (15°C, 20°C, 25°C, 30°C and 35°C) under laboratory conditions. In all cases an excellent fit of the model equation to the experimental data was obtained, the worst fit (R² = 0.997) was achieved for seeds germinated at 35°C, for all other cases R² reached 0,999. Analysis of the parameters of Gompertz equation allowed for a detailed evaluation of kinetics of tomato seed germination.
