Abstract
Cilj istraživanja bio je utvrditi alelopatski utjecaj vodenih ekstrakata korovne vrste Polygonum lapathifolium L. na klijavost i početni porast soje. U laboratoriju u petrijevim zdjelicama ispitani su ekstrakti pripremljeni od suhe mase stabljike i lista vrste P. lapathifolium u koncentracijama od 0, 1, 5 i 10% (0, 10, 50 i 100 g biljne mase na 1 litru destilirane vode). Rezultati su pokazali da vodeni ekstrakti nisu značajno utjecali na klijavost soje, najviše za 6,5%. Inhibicija duljine korijena klijanaca kretala se od 36,2 do 71,2%. Više koncentracije (5 i 10%) oba ekstrakta značajno su smanjile duljinu korijena, dok je 1% ekstrakt lista stimulirao rast korijena. S povećanjem koncentracije ekstrakata duljina izdanka i svježa masa klijanaca soje se proporcionalno smanjivala, u prosjeku za 32,9 odnosno 34,7%. Ekstrakti pripremljeni od stabljike imali su jači inhibitorni utjecaj na klijavost, duljinu korijena i svježu masu klijanaca soje, a ekstrakti lista na prosječno vrijeme klijanja i duljinu izdanka.

The aim of the study was to determine allelopathic effect of water extracts from weed species Polygonum lapathifolium L. on germination and initial growth of soybean. Water extracts from dry stems and leaves of P. lapathifolium at 0, 1, 5 and 10% concentrations (0, 10, 50 and 100 g of plant biomass) were examined under laboratory conditions using Petri dishes. Results showed that germination was not significantly affected, only up to 6,5%, when extracts were applied. Inhibition of root length of soybean seedlings ranged from 36.2 to 71.2%. Higher concentrations (5 and 10%) of both extracts significantly reduced, while 1% leaf extract showed stimulatory effect on soybean root length. With the increase of extract concentration, shoot length and fresh weight of soybean seedlings proportionately decreased, on average for 32.9 and 34.7%, respectively. Extracts prepared from stems had a stronger inhibitory effect on seed germination, root length and fresh weight of soybean seedlings, and leaf extracts had greater inhibitory effect on the mean germination time and seedling length
