The sunflower species Helianthus annuus L. belongs to the group of oil plants and it is considered to be one of the most important sources of vegetable oil used in human nutrition. The analyzed plant material was represented by the following hybrids: Armada Clearfield, Duet Clearfield, Meteor Clearfield, DT5234 Clearfield, P64LE25, DT6004, EXS7016 and Pokora. There have been made determinations regarding germination capacity, seed vigor expressed by electrolyte leakage, reserve lipids content, lipase activity and root length increase. Duet and Armada achieved the highest germination capacity, the leakage of electrolytes during imbibition directly influencing seed germination. The lipid content of the analyzed hybrids did not similarly influence germination and the radicle development took place 48 hours after the induction of the germination process, which can be explained by a quick mobilization and biodegradation of the organic substances under the influence of the lipase's increased activity.
