1	Morfologická plasticita chrpy luční \kur{(Centaurea jacea L.).} / Morphologic plasticity of \kur{Centaurea jacea.} KARÁSEK, Jakub January 2010 (has links) Morphological plasticity of brown knapweed (Centaurea jacea L.) was examined. South bohemian populations of subsp. jacea were compared to plasticity in larger area. The plasticity of local population overlaps with both subspecies. The correlation between abiotical factors and determination characteristics were found. Molecular survey using ISSR method shows no difference between subspecies. The final resolution of subspecies existence will be questioned in following study.
