Abstract
V celotni lesni zalogi gozdnih sestojev v Sloveniji se zmanjšuje delež jelke (Abies alba Mill.). Za ustrezno gojitveno in gozdnogospodarsko obravnavo gozdnih sestojev z jelko je pomembno poznavanje prirastoslovnih značilnosti. V raziskavi smo se omejili na debelinsko priraščanje jelke, ki smo ga analizirali s podatki s stalnih vzorčnih ploskev za 73 gozdnogospodarskih enot(N = 42.265 jelk). Povprečni letni debelinski prirastek jelke v izbranih enotah je znašal 3,43 0,25 mm. Variabilnost debelinskega priraščanja jelk jebila izrazita (KV = 75 %). Multivariatna analiza je pokazala značilen vpliv socialnega razreda drevesa, sestojne temeljnice, deleža bukve v sestoju, razvojne faze in rastiščne skupine na debelinski prirastek jelke. Izračunani so bili nekateri parametri modela priraščanja jelk in jelovih sestojev ob različnih sestojnih gostotah. V razpravi presojamo uporabnost in pomen rezultatov za gospodarjenje z jelko.

Title:Characteristics of diameter growth of silver fir (Abies alba Mill.) in Slovenia
Abstract:
Proportion of silver fir (Abies alba Mill.) in the total growing stock of forest stands in Slovenia is decreasing. Therefore the knowledge on growth characteristics of silver fir is crucial for its appropriate treatment in forest management. Diameter growth of silver fir was analyzed with the data from permanent sampling plots in 73 forest management units (42,265 silver firs). Mean annual diameter increment in the study area was 3.43 0.25 mm; its variability was significant (CV = 75 %). Multivariate analysis showed significant influence of social class, forest stand basal area, proportion of European beech (Fagus sylvatica L.) in the forest stand, the developmental phase and forest site stratum on the diameter increment of silver fir. A silver fir forest stand growth model with regard to various stand densities was calculated. In the discussion, the applicability and importance of the results for future forest management with silver fir were evaluated.
