Secondary Quercus petraea phytocenosis of the sub-pannonian region of Slovenia (Syntaxonomic problem of the secondary associations of Calluno-Quercetum and Leucobryo-Quercetum) / Sekundarna gradnova fitocenoza subpanonskega območja Slovenije …

Abstract

More recent study of secondary sessile oak phytocenoses on primary habitats of the association Blechno-Fagetum have shown that only one association appears, Calluno-Quercetum petraeae, with two sub-associations – typicum and pinetosum sylvestris. It was shown that the other association, Leucobryo-Quercetum petraeae, is floristically the same as Calluno-Quercetum petraeae. In addition to the aforementioned new sub-associations, we also recorded a new variant with manna ash, Calluno-Quercetum petraeae var. Fraxinus ornus, which is presumed to grow on habitats of the related association, Castaneo-Fagetum.

Novejša preučevanja sekundarnih fitocenoz gradna na primarnih rastiščih asociacije Blechno-Fagetum so pokazala, da se pojavlja le ena asociacija Calluno-Quercetum petraeae z dvema subasociacijama –typicum in pinetosum sylvestris. Za drugo asociacijo Leucobryo-Quercetum petraeae se je izkazalo, da je floristično enaka asociaciji Calluno-Quercetum petraeae. Poleg prej omenjenih novih subasociacij smo zabeležili še novo varianto z malim jesenom Calluno-Quercetum petraeae var. Fraxinus ornus, ki domnevno porašča primarna rastišča sorodne asociacije Castaneo-Fagetum.
