Botany

Phytosociological study ofLigularia Sibirien (L.) Cass, habitats from Zänoagei Gorges (Bucegi Mountains), Romania

Byoforms analysis of

3. Geo-elements analysis

The geographycal structure of the studied areas reveal the participation of numerous cathegories of geoelements. It can be observed that the floristic elements in Cirsio waldsteinii- Heracleetum transsilvanici Pawl, et Walas 1949 plant association are represented by Eurasian species (27.27%), folowed by European (20%) and Central-Europe (12.72%) species. (Fig. 4).

4. Karyological analysis

Regarding karyological analysis, can be noted the high share of polyploid and diploid species, thus it can be concluded that the studied association includes relict elements resistant to extreme environmental conditions, being possible due to the high conservation degree of the site. (Fig. 5) The high percentage of polyploid species indicates the zoo-anthropogenic pressure
