20.500.12556/RUL-69608 Prevrščanje dreves v optimalni fazi bukovega gozda Differentiation in mature beech stands Prispevek obravnava rezultate raziskave zgradbe bukovih gozdov Slovenije na 18 rastiščnih enotah. Analizirani bukovi debeljaki so enomerni, vendar glede starosti izkazujejo določeno raznodobnost. Raziskava je bila usmerjena v ugotovitev starostne zgradbe sestojev ter v proces prevrščanja, ki zajema časovni razmak 60 let. Podrobno so obravnavani tisti osebki, ki tvorijo zgornjo višino sestoja, to je 100 najdebelejših na ha. Prevrščanje teh dreves je v debeljakih razmeroma skromno, na posameznih rastiščih celo neznatno. Drevesa, ki tvorijo zgornjo višino sestoja, so praviloma tudi nekoliko starejša od preostalih, torej tista, ki so pričela rasti že v začetnem delu pomladitvene dobe The paper discusses results of a study on the composition of beech stands in 18 site units in Slovenia. The analysed mature beech stands are uniform but are characterised by certain uneven-agedness. The aim of the study was to determine age composition of these stands and to examine differentiation process within a period of 60 years. Top height trees, that is a hundred largest trees per hectare, are dealt with in detail. The differentiation process of these trees was relatively modest in mature stands, even insignificant in individual sites. These top height trees are, as a rule, a little older than other trees, that is trees which started growing early in the regeneration period. bukev socialni sestop prevrščanje starostna zgradba beech differentiation process suppression and natural mortality shifting age structure true false false Slovenski jezik Angleški jezik Znanstveno delo 2015-07-10 21:33:00 2015-07-10 21:33:00 2024-08-10 03:59:06 0000-00-00 00:00:00 1996 0 0 Str. 5-32 Št. 49 1996 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*17Fagus silvatica (L.):630*22 0351-3114 190630 Kotar_1996.pdf Kotar_1996.pdf 1 C143A87FA469FB37752B8906C83116D0 fbd3daf513092b9bcc17af4ffbd87b8c3a53a92fc5be34041a0c79c6ee37c9ce 68110596-a1b3-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=100834 Biotehniška fakulteta 0 0 0
