Abstract
Cilj istraživanja bio je utvrditi alelopatski učinak peršina (Petroselinum crispum Mill.) na klijavost i rast korovne vrste strjeličaste grbice (Lepidium draba (L.) Desv.). U petrijevim zdjelicama istraživan je učinak zajedničkog klijanja sjemena peršina i strjeličaste grbice te utjecaj vodenih ekstrakata u koncentracijama od 5 i 10% (50 i 100 g na litru destilirane vode). U posudama s tlom ispitivan je utjecaj vodenih ekstrakata od svježe mase peršina u istim koncentracijama te utjecaj svježih i suhih ostataka peršina u dozama od 10 i 20 g/kg tla. Zajedničko klijanje sjemena imalo je stimulativni utjecaj na duljinu korijena, ali je smanjilo duljinu izdanka i svježu masu klijanaca strjeličaste grbice. U pokusima u petrijevim zdjelicama, vodeni ekstrakti od svježe i suhe mase peršina smanjili su klijavost strjeličaste grbice, ali su pokazali i pozitivni i negativni utjecaj na ostale parametre. Najviša koncentracija ekstrakta suhe mase potpuno je inhibirala klijavost grbice (100%). U pokusima s posudama, ekstrakti od svježe mase peršina djelovali su pozitivno na rast korovne vrste, osim na duljinu korijena, koja je bila inhibirana s višom koncentracijom za 4,2%. Svježi biljni ostatci peršina smanjili su klijavost i duljinu izdanka grbice. Suhi ostatci promovirali su klijavost i rast grbice, ali su imali negativan učinak na duljinu korijena

The aim of the study was to examine allelopathic effect of parsley (Petroselinum crispum Mill.) on germination and growth parameters of weed species hoary cress (Lepidium draba (L.) Desv.). Cogermination of hoary cress with parsley seeds, water extracts from fresh and dry parsley biomass in concentrations of 5 and 10% (50 and 100 g per litre of distilled water) were evaluated in Petri dishes. Effect of water extracts from fresh parsley biomass in aforementioned concentrations as well as effects of fresh and dry parsley residues in two rates (10 and 20 g/kg of soil) were examined in pots with soil. Cogermination of seeds stimulated root length, but decreased shoot length and fresh weight of hoary cress seedlings. In the Petri dish assay, extracts from fresh and dry parsley biomass reduced germination of hoary cress, but had both stimulatory as well as inhibitory effect on other parameters. The highest concentration of dry biomass extract completely reduced germination rate of hoary cress (by 100%). In the pot experiment, extracts from fresh parsley biomass had stimulatory effect on weed growth parameters except for root length which was inhibited with higher concentration by 4.2%. Fresh parsley residues reduced germination, root and shoot length of hoary cress, while dry parsley residues promoted measured parameters, with the exception of root length.
