Abstract
Pokus je proveden kako bi se utvrdio alelopatski utjecaj vodenih ekstrakata korovne vrste kiseličasti dvornik (Polygonum persicaria L.) na klijavost i početni rast dva kultivara soje (Ika i Sanda). Vodeni ekstrakti od suhe stabljike i listova P. lapathifolium u koncentracijama od 1, 5 i 10% ispitani su u laboratorijskim uvjetima koristeći petrijeve zdjelice. Rezultati su pokazali da se kultivari soje razlikuju u njihovoj reakciji i osjetljivosti na alelopatski utjecaj ekstrakata kiseličastog dvornika. Općenito, kultivar Ika je bio osjetljiviji od kultivara Sanda. U prosjeku, ekstrakti nisu značajno utjecali na klijavost soje. Najveće smanjenje klijavosti zabilježeno je s 5%-tnim ekstraktom lista i to za 10,1%. Međutim, kod Sande je utvrđen nešto veći utjecaj na klijavost. Ekstrakti su pokazali veći stimulativni i inhibitorni učinak na duljinu korijena i izdanka te svježu masu kultivara Ika. Ekstrakti stabljike i lista u koncentracijama od 10% imali su najviši inhibitorni učinak, čak do 48,8%. Povećanje koncentracije rezultiralo je većim inhibitornim učinkom, dok su niže koncentracije uglavnom stimulirale rast soje.
Abstract (english)
The experiment was conducted to assess allelopathic potential of water extracts from weed species pale persicaria (Polygonum lapathifolium L.) on germination and initial growth of two soybean cultivars (Ika and Sanda). Water extracts from dry stems and leaves of P. lapathifolium in concentrations of 1, 5 and 10% were examined under laboratory conditions using Petri dishes. Results showed that soybean cultivars differed both in their response and sensitivity to allelopathic effect of pale persicaria extracts. Overall, cultivar Ika was more susceptible that cultivar Sanda. On average, germination of soybean was not significantly affected by extracts. The highest germination reduction was recorded with 5% leaf extract for 10.1%. However, Sanda germination was slightly more affected. Contrary, extracts showed greater effect, both stimulatory and inhibitory, on root and shoot length and fresh weight of Ika. Both stem and leaf extracts in 10% concentration had the highest inhibitory effect, up to 48.8%. The increase in extract concentration exhibited higher inhibitory effect, while the lowest concentration generally stimulated soybean growth.
