Razvoj mladja v pragozdu Pečka od leta 1963 : diplomsko delo - univerzitetni študij = Development of regeneration in virgin forest Pečka from year 1963 : graduation thesis - university studiesKramberger, Aljoša, 1983-, gozdarNamen raziskave je bil preučevanje naravnega pomlajevanja drevesnih vrst in osnovnih ekoloških dejavnikov na vzorčnih ploskvah v pragozdu Pečka. Na 164 sistematično določenih vzorčnih ploskvah ... velikosti 2 x 2 m so bile izmerjene vrednosti direktne in difuzne svetlobe na različnih višinah, ocenjena zastrtost tal z zeliščno vegetacijo, mladjem in drevesnimi ostanki, v okolici ploskve so bili izmerjeni ekspozicija, nagib in temeljnica sestoja in določena razvojna faza pragozda. Povprečna vrednost difuzne svetlobe je bila 4,0 %, direktne pa 3,2 %. Skupna gostota mladja brez klic je znašala 19954 ha-1. V mladju je prevladovala bukev (94 %), sledila sta ji jelka (4 %) in gorski javor (2 %). Delež bukve se je z naraščajočo višino mladovja povečeval. Gostote jelovega mladja so bile nizke, jelke v višinskem razredu nad 20 cm nismo zabeležili. Delež jelke v temeljnici se je v obdobju od leta 1893 do leta 2007 znižal, delež bukve pa narasel. V mladju se je povečal delež delno in močno poškodovanih jelk. Prevladovale so razvojne faze s pomladkom. Ugotovljena je bila pozitivna povezava med difuzno svetlobo in povprečnim prirastkom bukovih poganjkov ter med bukvijo v razredu nad 20 cm in difuzno svetlobo. Ugotovljen je bila tudi negativna odvisnost med zastiranjem pritalne vegetacije in zastiranjem pomladka drevesnih vrst.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [A.
