Cytological, seed and epidermal studies were carried out of 9 taxa belonging to 4 genera 6 species the tribe Eupatorieae. Chromosome counts 2 species-Adenostemma caffrum (n=10) A. mauritianum are reported for first time from Nigerian flora report Ageratum conyzoides (n=18) differed earlier reports. The cytotypes in is flora. pollen fertility test all plants studied high this revealed that meios...

Previous chromosome information is restricted to nine species in the Asian Begonia sect. Petermannia. We present here first counts for 15 taxa and karyotype analyses 14 Petermannia addition with a Haagea. Among ca. 460 Petermannia, numbers of 24 are available together previous reports. taxa, they show diverse 2n=24–28, 28, 30, 36, 44. 12 2n=30 analyzed, two new 2n=30=16m+14sm(st)2sm 2n=30=8m+22...

The aim of the study was to determine chromosome number and nuclear DNA content an endemic plant, V. scamandri, using 14-week-old plants germinated from seed genetic stability based on flow cytometry analyses in callus tissue induced MS medium containing 1 mg/L Kin + 2,4-D 9-week-old propagated plants, developed 2 0.1 2,4-D. In mitotic counts showed scamandri had 2n = 16. Flow cytometric analys...

Homogyne alpina (L.) Cass. represents the only species of genus in Slovakia. This study characterizes H. terms chromosome counts, genome size, reproduction mode and distribution Three known cytotypes are known, which cytotype 2n = 160 is represented Slovak mountains has not been documented from other countries yet. Flow cytometric analyses showed size 2C 21.30 pg for petioles 21.82 seeds. Sexua...
