Abstract
Crna bazga (Sambucus nigra L.) široko je rasprostranjena ljekovita biljka s bogatim sadržajem biološki aktivnih spojeva. U ovom istraživanju procjenjen je alelopatski potencijal različitih koncentracija vodenih ekstrakata od suhe nadzemne mase crne bazge (S. nigra) na klijavost sjemena i rast klijanaca salate (Lactuca sativa L.). Niže koncentracije nisu imale značajan utjecaj, dok su više koncentracije pokazale potpunu inhibiciju klijavosti. Duljina korijena i izdanka klijanaca značajno su smanjene, posebice pri višim koncentracijama, od 42,8 % do 100 %. Pozitivno djelovanje na svježu masu zabilježeno je s najnižom koncentracijom vodenog ekstrakta. Vrijednost indeksa vigora klijanaca (SVI) snižena je u svim tretmanima. S obzirom na značajni inhibitorni potencijal, crna bazga (S. nigra) ističe se kao zanimljiva vrsta za daljnje istraživanje.Elderberry (Sambucus nigra L.) is a widely distributed medicinal plant with a rich content of bioactive compounds. This study assessed the allelopathic potential of different concentrations of water extracts from the dry above-ground biomass of elderberry (S. nigra) on seed germination and seedling growth of lettuce (Lactuca sativa L.). Lower concentrations had no significant effect, while higher concentrations completely inhibited seed germination. Root and shoot length of seedlings were significantly reduced, especially at higher concentrations, ranging from 42.8% to 100%. Positive effects on fresh biomass were recorded with the lowest concentration of the water extract. Seedling vigor index (SVI) values were reduced in all treatments. Given its significant inhibitory potential, elderberry (S. nigra) stands out as an interesting species for further research
