VEGETATION OF THE CLASSES Stellarietea mediae AND Agropyretea repentis IN THE VINEYARDS OF BOSNIA AND HERZEGOVINA

Abstract

This paper shows the results of many years researches of the weed vegetation of vineyards in western Balkan which includes eight associations: Panico-Galinsogetum parviflorae Tüxen et Becker 1942, Panico-Portulacetum oleraceae Lozanovski 1962, Cynodono-Sorghetum halepensae (Laban 1974) Kojić 1979, Amarantho-Fumarietum Tüxen 1955, Diplotaxietum muralis Kovačević 2013, Convolvulo-Polygonetum aviculare Kovačević 2014, Erigerono-Setarietum glaucae Šumatić 1997 and Convolvulo-Agropyretum repentis Felföldy 1943. By projecting the plant communities on the main components (Principal Component Analysis) and comparing them to the ecological indices (variables), it shows that Cynodono-Sorghetum halepensae and Diplotaxietum muralis are similar according to their humidity (F) and temperature (T) re-quirements and Cynodono-Sorghetum halepensae and Diplotaxietum muralis are similar according to their chemical reaction of the soil (R). Amarantho-Fumarietum and Erigerono-Setarietum glaucae are the simi-lar according to their demands for the light (L).
