Abstract

V Poljanski dolini sta bili izbrani dve raziskovalni ploskvi na rastišču Blechno-Fagetum, kjer je v sestojih prevladoval graden. Skupno je bilo izmerjenih 33 dreves gradna. Preden so bili posekani, jim je bila ocenjena kakovost debel. Na podlagi debelnih analiz je bila ugotovljena višinska, debelinska in volumenska rast. Poleg tega je bilo preizkušeno, ali klimatski dejavniki vplivajo na širino branike. Ugotovljena je bila zelo počasna rast dreves, šibek klimatski signal v branikah, boljše priraščanje vladajočih kot podstojnih dreves in boljše priraščanje dreves z veliko kot dreves z majhno krošnjo. Ugotovljen sortimentni sestav kaže zelo nizko kakovost debel. Med napakami so bile izredno pogoste zimavost, trohnoba in tudi kolesivost.

Secondary title: Growth of Sessile oak on the Blechno-Fagetum site in Poljanska dolina
Secondary abstract: In Poljanska dolina two research plots were selected on site Blechno-Fagetum, in the stands dominated by sessile oak. Altogether, 33 sessile oaks were measured, their stem quality analyzed and then they were cut down. On the basis of stem analyses height growth, diameter growth and volume growth were established. Beside, the climate factors influence on the tree ring width was tested. It was established that the growth is very slow, climate signal in tree rings is weak, growth of dominant is better in comparison with dominated oaks and growth of trees with bigger crowns is better as well. The assortment structure indicates very low stem quality. Among stem defects frost cracks, rot and partially ring shakes are very frequent.
