dc.description.abstractAster lanceolatus Willd. je zeljasta perena koja se smatra invazivnom u velikom broju evropskih zemalja. U Srbiji, ova biljka naseljava vlažna staništa i formira široko rasprostranjene monodominantne sastojine. Cilj ovog istraživanja je da utvrdi da li generativno razmnožavanje ima važnu ulogu u širenju ove vrste na nova područja. Ahenije nastale iz bočnih i terminalnih glavica su sakupljene na 13 lokaliteta u Srbiji. Utvrđen je broj ahenija nastalih iz jedne glavice, kao i parametri klijanja semena. Rezultati su pokazali da se parametri klijanja nisu razlikovali u odnosu na mesto nastanka ahenija, već u odnosu na lokalitet sa koga su one sakupljane. Ovo istraživanje je potvrdilo da A. lanceolatus stvara veliku količinu vijabilnog semena koje klija u količini koja je dovoljna da obezbedi uspešno širenje vrste na nova područja.sr
dc.description.abstractAster lanceolatus Willd. is a herbaceous perennial that is considered invasive in many European countries. In Serbia, this plant inhabits wet habitats and forms widespread monospecific stands. The objective of this research is to determine whether generative reproduction has an important role in the expansion of this species to new areas. In 13 different localities, fruit heads were collected from lateral and terminal parts of infructescence. Seed quantity and germination parameters were determined for seeds in the fruit heads. The results showed that the position of the fruit heads did not have a major impact on germination parameters. However, germination parameters differed among the localities. The findings of this study suggest that A. lanceolatus produces a great amount of viable seeds that germinate in an amount sufficient to ensure a successful spread of this invasive species to new areas.en
