Abstract
Analizirali so zgradbo in rast raznomernih sestojev ter jo primerjali z enomernimi. Raziskavo so izvedli v gozdnogospodarski enoti Poljane, na rastiščih dinarskega jelovo-bukovega gozda (Omphalodo-Fagetum). Izvrednotili so naloge 10 raziskovalnih ploskev v raznomernih in 10 ploskev v enomernih sestojih. Poleg tega so izvedli debelne analize skupno 225 dreves. Ugotovili so visoke lesne zaloge, v sestojih dominirata jelka in smreka. Vitalnost dreves je bila solidna. Starosti čakalcev, štarterjev in tekačev se ne razlikujejo bistveno, zmagovalci pa so občutno starejši. Najdlje v zastrtosti vztraja jelka. Smreka ima ugodnejšo sortimentno strukturo v raznomernih sestojih. Jelka je manj kakovostna kot smreka. Jelka v rasti praviloma kulminira zadnja. Velik del dreves ima več kulminacij tekočih višinskih, radialnih in volumenskih prirastkov. Sečnja spodbudi priraščanje dreves, najbolj dominantnih. Ugotovili so večji vpliv temperature kot padavin na širino branik.

Abstract:
They have analysed the structure and the growth of irregular stands and compared it with even-aged ones. Their research has been carried out in the Poljane forest management unit, on the sites of the Dinaric silver fir-beech forest (Omphalodo-Fagetum). They have evaluated 10 research plots in irregularstands and 10 plots in even-aged stands. In addition they have carried out a stem analysis of totally 225 trees. They came to the conclusion of high level of growing stock; fir and spruce are the dominant tree species in the stands. The vitality of tress was solid and firm. The ages of the waiters , starters and runners do not differ significantly, while the winners are significantly older. The period of suppressed growth was the longest for fir threes. The spruce tree has a more favourable assortment structure in irregular stands. The fir tree is of lower quality compared to the spruce tree. As a general rule, the fir tree culminates the last. A large portion of trees has several culminations of height, radial as well as volume current increments. The felling stimulates the increment of trees, particularly the most dominant ones. They have also determined a greater influence of temperature compared to the precipitation on the ring width.
