Contributions to the phytosociological study of Sessile and Turkey oak forests in the Orastie area (Central-Western Romania)

In the current paper we present a phytosociological study of the phytocoenoses of the association Quercetum petraeae-cerris Soó 1963 (Syn.: Quercetum polycarpae-cerris G. Popescu 1988) identified in the Or tie river basin, situated in the central-western part of Romania.The characterisation of the association under analysis as well as the presentation of the phytosociological table have been done by selecting the most representative relevés performed in the Turkey and Sessile oak forests of the lower and central parts of the Orastie river basin (Culoarul Or tiei).This paper aims at analysing the phytocoenoses of the association Quercetum petraeae-cerris Soó 1963 in terms of physiognomy and floristic composition, life forms spectrum, floristic elements, and ecological indices.
