PHYSIOLOGICAL PARTICULARITIES OF HYGROPHILOUS PLANTS FROM DOMOGLED-CERNA VALLEY NATIONAL PARK
The vegetal asociation Telekio-Petasitetum (Morariu 1967, Resmerita et Ratiu,
1974) is well represented in Domogled â€“Cerna Valley National Park, across Cerna`s valleyÂ and its main tributaries. The two enlightening species, Petasites hybridus and TelekiaÂ speciosa are characterized by their tall stem, big leaf area and a high photosyntheticÂ efficiency. The water regime of these plants is a characteristic for the hygrophilousÂ species, with a high water content in tissues and raised transpiration values. Due to theirÂ evolved root system and their good capacity of regeneration, the plants that have beenÂ taken in this study have an important ecological role, forming true corridors along riversÂ and contributing at the consolidation of river banks.
