The paper presents the results of testing of seed germination and initial growth of seedlings of four sunflower hybrids: 2950, 2951, 3007, 3009) at different temperatures: 20° C, 25°C, 30°C. In all hybrids tested, the highest germination of sunflower seeds was achieved at a temperature of 30° C; however, in two tested hybrids (2950 and 3007) no significant difference (p ≥ 0.05) was found between germination at a temperature of 30° C and 25° C. Correlation interdependence between germination and stem growth was positive and statistically significant (r=0.576p ≤ 0.05), while a positive but not statistically significant interdependence was also determined between germination and radicle growth (r=0.252p ≥ 0.05).
