20.500.12556/RUL-183869 Kakovost in pomlajevanje zelenega bora (Pinus strobus) v Sloveniji Quality and regeneration of eastern white pine (Pinus strobus) in Slovenia Namen magistrskega dela je celovito ovrednotiti stanje zelenega bora (Pinus strobus L.) v Sloveniji ter ugotoviti značilnosti njegovega pomlajevanja. Raziskava je bila izvedena na šestih raziskovalnih ploskvah (Mlake, Velika Bukovica, Smlednik, Kidričevo, Njivica in Dutovlje), kjer smo na podlagi terenskih meritev analizirali vitalnost, dimenzijsko strukturo, kakovost sestojev in dinamiko pomlajevanja. Preučevali smo odvisnost količine pomladka od oddaljenosti od matičnega sestoja ter poškodovanost mladovja zaradi rastlinojede divjadi. V vsakem sestoju smo sistematično popisali pomladek na ploskvah znotraj in zunaj sestojev, ocenili vitalnost in kakovost odraslih dreves po petstopenjski lestvici ter uporabili različne statistične metode za preverjanje hipotez. Rezultati so pokazali, da obstajajo pomembne razlike med ploskvami v vitalnosti (najvišja 4,74, najnižja 2,82), povprečnem premeru (od 30,3 cm do 51,2 cm) in kakovosti debel (najvišja 2,7, najnižja 2,2). Najintenzivnejše pomlajevanje je bilo zabeleženo v Mlakah, medtem ko je bilo statistično značilno zmanjševanje količine pomladka z oddaljenostjo od matičnega sestoja potrjeno le v Smledniku (R² = 0,514; p < 0,013). Ugotovitve kažejo, da ima zeleni bor na posameznih rastiščih lahko potencialno pomembno vlogo v prihodnji gozdni sestavi, vendar bo razvoj odvisen od lokalnih razmer in gozdnogospodarskih usmeritev. The aim of this master’s thesis was to comprehensively evaluate the status of eastern white pine (Pinus strobus L.) in Slovenia and to determine the characteristics of its regeneration. The study was carried out on six research plots (Mlake, Velika Bukovica, Smlednik, Kidričevo, Njivica and Dutovlje), where field measurements were used to analyse stand vitality, dimensional structure, stem quality and regeneration dynamics. We examined the relationship between seedling density and the distance from parent stands, as well as browsing damage by ungulates. In each stand, regeneration was systematically surveyed on plots inside and outside the stands, while the vitality and quality of mature trees were assessed using a five-point scale. Various statistical methods were applied to test the hypotheses. The results showed significant differences between plots in vitality (highest 4.74, lowest 2.82), mean diameter (30.3–51.2 cm) and stem quality (highest 2.7, lowest 2.21). The most intensive regeneration was recorded in Mlake, while a significant decline in seedling density with increasing distance from the parent stand was confirmed only in Smlednik (R² = 0.514; p < 0.013). The findings show that eastern white pine may play a potentially important role in future forest composition at certain sites, but its development will depend on local site conditions and silvicultural strategies. zeleni bor pomlajevanje kakovost vitalnost eastern white pine regeneration quality vitality true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2026-06-20 07:15:12 2026-06-20 07:15:27 2026-06-22 10:16:46 0000-00-00 00:00:00 2026 0 0 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 280153 282392067 57887.pdf 57887.pdf 1 B381BFEF5A97F8660A36D7AC3A2F4CC0 7b3e612db1c76a9df500976c1c3b468f332c720d6d99426aea15f78de5d507f8 feab0d62-6c66-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=236176 Biotehniška fakulteta 0 0 0
