The genus Bromus subgen. Festucaria is a widespread Old World and New World taxon having genomes A, B and L, distinguished cytogenetically. Stebbins (1981) suggested that evolution in Bromus went from the small genomes A and B to the large genome L. Thus, Old World species with genomes A and B could be ancestral to New World species with genome L. To test this hypothesis we carried out RAPD analysis...
A numerical analysis of the phytosociological relevés from ancient and recent woodland on a mesic forest site in central Poland was carried out. Three groups of forest stands were recognised: planted with Pinus, recent and ancient oak-hornbeam Tilio-Carpinetum. The species of ancient woodland occurred mainly in ancient oak-hornbeam forest stands, however some ferns: Dryopteris carthusiana, D. dilatata...
RAPD analysis was applied to nine Bromus species (B. fasciculatus, B. arvensis, B. scoparius, B. hordeaceus, B. squarrosus, B. carinatus, B. willdenowii, B. erectus, B. inermis) belonging to four subgenera: subg. Stenobromus, subg. Bromus, subg. Ceratochloa, and subg. Festucaria. With 10 out 13 primers a considerable degree of polymorphism was detected at the interspecific level, and some bands obtained...
The karyotype structure of Aconitum lasiocarpum (Rchb.) Gáyer was investigated conventionally and by Giemsa C-banding. The chromosome complex of A. lasiocarpum is composed of two distinguishable pairs of long chromosomes and six pairs of considerably shorter chromosomes. Nucleolar organizers are localized on the shorter arms of three (1, 3 and 5) chromosomes. In all analyzed plants the first and third...
