Occurrence of Polypodium xmantoniae and new localities for P. interjectum in the Czech Republic confirmed using flow cytometry

Popis výsledku v původním jazyce

Flow cytometry measurements confirmed the occurrence of Polypodium xmantoniae (P. interjectum x P. vulgare) at three localities in the eastern part of the Czech Republic (Blansko and Rudice N of Brno and Javoříčko WNW of Olomouc). Nuclear DNA contents (+/- Sx) were determined for P. vulgare (2C = 29.00 +/- 0.32 pg), P. xmantoniae (2C = 37.18 +/- 0.38 pg) and P. interjectum (2C = 45.24 +/- 0.31 pg) using a PAS Partec GmbH flow cytometer (PI staining / standard Vicia faba, 2C = 26.9 pg). The relative DNAcontent ratio was measured in all pairs of taxa (+/- Sx range), i.e. P. xmantoniae : P. vulgare = 1.340 +/- 0.008; P. interjectum : P. vulgare = 1.681 +/- 0.003; P. interjectum : P. xmantoniae = 1.255 +/- 0.008. Six new localities for Polypodium interjectum were found in the region of Moravský Kras (= Moravian Karst, N of Brno). From the PI/DAPI index it can be inferred that the AT/GC ratio (or heterochromatin occurrence) is 1.05x bigger in P. xmantoniae than in P. vulgare and 1.08x bigg
