Sažetak
In the laboratory of the Agricultural faculty in Osijek - CROATIA, the analysis of seed size (seed fractions of 3.5 mm, 2.75 mm and 2.5 mm) on sprouting energy, germinability and rotlet length has been was made, during 1994 and 1995. Fakir and Osječanin sunflower varieties were used for the analysis. Seed fraction of 3.5 mm achieved the greatest sprouting energy (variety Fakir 80.5% and variety Osječanin 84.4%). Seed fraction of 2.5 mm achieved the smallest sprouting energy in variety Fakir (69.0%) and seed fraction of 2.75 mm in variety Osječanin (80.0%). By statistical analysis, between investigated seed fractions, demonstrated differences of sprouting energy in variety Fakir were significant (p < 0.05*) and in variety Osječanin were not significant (ns). Seed fractions of 3.5 mm achieved the greatest germinability in both varieties (variety Fakir 90.8% and variety Osječanin 85.6%). Seed fractions of 2.5 mm achieved the smallest germinability in both varieties (variety Fakir 88.0% and variety Osječanin 83.8%). By statistical analysis the values obtained by measuring germinability in both varieties, demonstrated differences between seed fractions which were not significant (ns). Seed fractions of 3.5 mm achieved the greatest rootlet length in both varieties (variety Fakir 7.95 cm and variety Osječanin 7.15 cm). Seed fractions of 2.5 mm achieved the smallest rootlet length in both varieties (variety Fakir 5.86 cm and variety Osječanin 6.17 cm). By statistical analysis, between investigated seed fractions, demonstrated differences of sunflower rootlet length were very significant (P < 0.01**), in both varieties.
