Variability of seed germination on the third day and initial growth of sunflower hybrid seedlings at different temperatures

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