Abstract
Namen prispevka je ugotoviti produkcijske sposobnosti jelovih (Abies alba Mill.) sestojev, opozoriti na nekatere rastne značilnosti in prikazati kakovostno strukturo jelovih dreves. V raziskavo smo zajeli 14 rastiščnih enot. Na vsaki smo postavili 5 raziskovalnih ploskev v odraslih, nerazgrajenihsestojih, kjer je jelka prevladovala. Produkcijska sposobnost rastišč se zmanjšuje z nadmorsko višino in skalovitostjo, večja pa je na konkavnih terenih in osojnih ter vzhodnih legah. V analiziranih sestojih so sejelke pomladile v 5 do 70 letih. Na veliki večini rastiščnih enot se višinski in debelinski prirastek zmanjšujeta tudi po prirastni depresiji v obdobju 1960 do 1990. Podstojne jelke so v povprečju za 10 do 40 let mlajše oddominantnih, na manj produktivnih rastiščih so razlike manjše. Sortimentna struktura jelke je ugodnejša na rastiščih (nekarbonatnih) jelovij, deloma tudina bukovih rastiščih, navzdol pa izstopajo dinarski jelovo-bukovi sestoji.Vrednost jelke je v zelo veliki meri pogojena s prsnim premerom, v majhni meri pa tudi z utesnjenostjo oziroma velikostjo krošnje, večvrhatostjo ter boniteto rastišča.

Title:Growth and yield characteristics of European Silver Fir (Abies alba Mill.) in Slovenia
Abstract:
The aim of this paper is to establish site productivities of Silver fir (Abiesalba Mill.) stands, to show some growth characteristics and to analyze the quality structure of Silver fir trees. The research was carried out on 14 site units. On each, 5 research plots in mature, compact stands where Silver fir dominated were set. Site productivity decreases with the altitude and stoniness while being higher on the concave sites and on the shady or east wards exposed positions. Silver firs from the analyzed stands regenerated in periods lasting 5-70 years. The height and diameter increments are still decreasing after the increment depression in years 1960-1990 on the majority of the sites. The overtopped Silver firs are 10-40 years younger than the dominant ones. The differences are lower on the less productive sites. The assortment structure of Silver fir is more favorable on Silver fir (noncarbonated) sites, partially also on beech sites, while the dinaric Silverfir-beech stands showed the worst structure. The value of the Silver firstems depends to a very large extent on the diameter at breast height, while crown size or crown isolation, forking and site productivity have little effect.
