Rastne značilnosti smreke na bukovih rastiščih z belkasto bekico v Pahernikovih gozdovih

Murn, Tadej (author), Kadunc, Aleš (mentor)

V diplomski nalogi so predstavljeni rezultati rastnih analiz smreke na bukovih rastiščih z belkasto bekico v Pahernikovih gozdovih. V ta namen smo zbrali podatke o drevesih in sestojnih parametrih na 15 ploskvah ter posekali skupno 75 dominantnih dreves smreke, pri katerih smo opravili debelne analize. Analizirali smo višinsko, debelinsko in volumensko rast ter izračunali rastiščne indekse. V nalogi je prikazana tudi sortimentna struktura hlodovine, analiza pojava trohnobe in povprečna višina čistega debla. Ploskve smo razdelili v tri stratume glede na delež smreke v temeljnici sestoja. Ugotovili smo, da izkazuje najvišje prirastke stratum z deležem smreke med 70 in 90 %, najnižje pa stratum z deležem smreke med 50 in 70 %. Trohnoba na panju je zelo pogosta.

• Title: Growth characteristics of norway spruce on beech sites with white wood rush in Pahernik forests

Abstract

This thesis presents results of growth analysis of Norway spruce on beech sites with White wood rush in Pahernik forests. For this purpose we collected data of trees and stand parameters on 15 sampling plots. 75 dominant spruce trees were also cut down in order to carry out the stem analysis. We analyzed height growth, diameter growth, volume growth, site index (SI100), timber quality, wood rottenness and height of the branch-free trunk. We devided the plots into 3 stratums according to the proportion of the spruce in the basal area of the stand. Results showed that increments are higher in stands with proportion of spruce between 70-90 %. The lowest values were established in stratum with proportion of spruce between 50 and 70 %. The rot on the stump was very frequent.
