The paper analyses the role of species and source population (provenance) of the planting stock of sessile and pedunculate oaks in the beech forest zone (alt. 550 m) in PLO 30 Drahanská Highland, Czechia. Sets of trees representing 5 sessile oak and 4 pedunculate oak provenances were studied in a provenance trial (7–9 years after outplanting) with focus on the survival rate, growth, stem quality, damage, spring phenology (budburst and leaf flushing), lammas growth and autumn leaf senescence. In the trial located at its local altitudinal maximum, sessile oak had higher mean height, lower proportion of damaged individuals, better stem quality, and it flushed earlier than alochtonous pedunculate oak. As to the role of provenance of planting stock, it has influenced the height, survival rate, budburst and leaf development of both oak species, as well as the stem quality of sessile oak. Across the species and provenances, individuals which flushed earlier and ceased vegetation later in autumn, were higher, had better stem quality, more and longer lammas shoots, and less damage.
