Abstract
Cilj istraživanja bio je ispitati alelopatski utjecaj kamilice (Matricaria chamomilla L.) na klijavost i početni rast korovne vrste strjeličaste grbice (Cardaria draba (L.) Desv.). Provedena su dva pokusa u laboratorijskim uvjetima kako bi se utvrdio utjecaj zajedničkog klijanja sjemena kamilice i streličaste grbice, te utjecaj vodenih ekstrakata kamilice. Ispitivani su vodeni ekstrakti od svježe i suhe mase kamilice u koncentracijama od 5 i 10% (50 i 100 g biljne mase na litru destilirane vode). Sjeme kamilice pri zajedničkom klijanju sa sjemenom grbice pokazalo je inhibitorni učinak na klijavost grbice do 10,8%, no nije bilo utjecaja na rast klijanaca. Ekstrakti kamilice od svježe i suhe mase pokazali su negativan učinak na klijavost, duljinu korijena i izdanka te svježu masu klijanaca grbice. S povećanjem koncentracije biomase kamilice u ekstraktima, mjereni parametri su se proporcionalno smanjivali. Ekstrakt suhe mase kamilice u koncentraciji od 10% imao je najveći učinak, te potpuno inhibirao (100%) svježu masu te duljinu korijena i izdanka grbice. U prosjeku, alelopatski učinak ekstrakata suhe mase bio je veći od ekstrakata svježe mase.

Parallel abstract (English)
The aim of the study was to determine allelopathic effect of chamomile (Matricaria chamomilla L.) on germination and initial growth of weed species hoary cress (Cardaria draba (L.) Desv.). Two experiments were conducted under laboratory conditions to determine effect of cogermination of chamomile and hoary cress seeds and effect of chamomile water extracts. Water extracts from fresh and dry chamomile biomass in concentrations of 5 and 10% (50 and 100 g of biomass per litre) were investigated. Chamomile seeds in cogermination with hoary cress showed inhibitory effect on weed seeds germination, up to 10.8%, while no significant effect on growth parameters was observed. Extracts from fresh and dry chamomile biomass showed inhibitory effect on germination, root and shoot length and fresh weight of hoary cress. With the increase of concentration, the measured parameters proportionately decreased. Extract from dry chamomile biomass in 10% concentration had the highest effect, completely inhibiting (100%) weed fresh weight and root and shoot length. On average, extracts from dry biomass had higher allelopathic potential compared to extracts from fresh chamomile biomass.
