The Arable Weeds of Plešivica Hills (NW Croatia)


Pages: 167-173


The arable weeds (segetal flora) were explored on Plešivica hills (NW Croatia) during vegetational seasons 2002 and 2003 at 10 locations. The common methods of plant recording, collecting and identification were applied in the research of the arable weeds. Th e nomenclature of plants was according to Tutin et al. (1964-1980, 1993). The total of 107 taxa of arable weeds that classified to 32 families was noted. The most represented families were Poaceae, Asteraceae and Fabaceae. Therophytes were dominant in the fields that were the subject of this research. Most of the species were the cosmopolites and the Euroasian origin. 78 weed species were noted in dense crop fi elds (wheat, barley). Some of them (Chamomilla recutita (L.) Rausch., Cirsium arvense (L.)Scop., Galium aparine L., Papaver rhoeas L., Stellaria media(L.)Vill. and Veronica persica Poir.) are the most harmful weeds of dense crops. 62 weeds were noted in maize fields. Some of them were typically row crop weeds, as for instance: Amaranthus retrofl exus L., Chenopodium album L., Ch. polyspermum L., Cirsium arvense, Convolvulus arvensis L., Digitaria sanguinalis (L.) Scop., Echinochloa crus-galli (L.) PB., Polygonum lapathifolium L. and Sorghum halepense (L.) Pers. Very invasive species Abutilon theophrasti Med. was found on the row crop fields. Very dangerous aeroallergenic species Ambrosia artemisiifolia L. was dispersed in many of the researched fields.
