Rastne značilnosti belega gabra (Carpinus Betulus L.) na Dolenjskem : diplomsko delo - univerzitetni študij 1. stopnja

Mirtič, Jaka (author), Kadunc, Aleš (mentor)

V diplomski nalogi so prikazani rezultati rastnih analiz belega gabra (Carpinus betulus L.) na Dolenjskem. V ta namen je bilo posekanih 90 belih gabrov in izvedene standardne debelne analize. Na podlagi fitocenološkega pregleda so bile določene 3 rastiščne enote, in sicer Abio albae-Carpinetum betuli, Hedero-Fagetum ter Vaccinio myrtilli-Carpinetum betuli. Prvi dve rastiščni enoti se nahajata na karbonatni matični podlagi, zadnja pa na silikatni. Izvrednotena je bila sortimentna sestava, ugotovljene zakonitosti višinske in debelinske rasti ter produkcijska sposobnost analiziranih rastiščnih enot. Rezultati so pokazali, da je rast na rastišču Vaccinio myrtilli-Carpinetum betuli nekoliko hitrejša, tu ima beli gaber tudi največjo konkurenčno moč. Ugotovljene vrednosti rastiščnega indeksa SI100 se nahajajo v intervalu med 24 in 27 m. Sortimentni sestav kaže na visok delež drv, kljub temu je znaten delež lesa primeren za tehnično rabo.

Abstract

The thesis exhibits results of European hornbeam (Carpinus betulus L.) growth analysis, performed in Dolenjska region. For this purpose, 90 trees of European hornbeam were cut down, and the standard stem analysis was carried out. Phytocenological analysis was used to determine 3 site units, namely Abioalbae-Carpinetum betuli, Hedero-Fagetum and Vaccinio myrtilli-Carpinetum betuli. First two site units are located on carbonate bedrock, and the last one on silicate bedrock. Stem quality structure was assessed; diameter and height growth characteristics and site productivity of analyzed site units were established. Results show that growth on the site unit Vaccinio myrtilli-Carpinetum betuli was somewhat faster, and that is where the European hornbeam is most competitive. The established values of site index SI100 are located in the interval between 24 and 27 m. Assortment structure shows a high share of fuel wood, in spite of that an important share of technical wood was established.
