A kék búzavirág (Centaurea cyanus L.) elterjedése a Kisalföld szántóföldjein
Pinke Gyula – Pál Róbert
The aim of the study is to show the distribution of Centaurea cyanus on Little Plain between 1993 and 1999 by using CEU mapping system. According to the floristic survey, Centaurea cyanus is not threatened by extinction in this region. Although it is rather absent on intensively cultivated farmlands its presence on small plots of extensive cultivation is still evident, either as an individual specimen or as a large expanse. The species is most likely to be found in the Camelino microcarpae-Anthemidetum austriacae association and shows highest abundance and dominance in its scleranthetosum subassociation, which is characteristic of moderate acidic sand soils.
