Variabilnost gostote lesa debla, vej in korenin jelk s snežniškega območja : diplomsko delo - visokošolski strokovni študij = Variability of wood density of trunks, branches and roots of fir trees in the Snežnik area : graduation thesis - higher professional studiesMartinčič, Andrej, 1986-Raziskovali smo variabilnost gostote znotraj drevesa in med posameznimi drevesi na istem rastišču območja Snežnika. Raziskava je temeljila na 19 drevesih jelke, ki jih je jeseni leta 2008 izruval ... vetrolom. Iz kolutov debel, vej in korenin smo izžagali radialne vzorce, jih razsekali na 2059 testnih vzorcev nepravilnih oblik, sušili na 103 °C do absolutno suhega stanja in nato tehtali na laboratorijski tehtnici. Vzorce smo v impregnacijski komori impregnirali z vodo. Maksimalno napojene smo potapljali v merilni valj in jim merili volumne. Natančnost meritev smo preverili še z Breuilovim živosrebrovim volumometrom. Ugotovili smo, da ima največjo povprečno osnovno gostoto les vej (595 kg/m3), zatem les debel (394 kg/m3), najmanjšo pa koreninski les (365 kg/m3). Največja povprečna osnovna gostota lesa debel je 509 kg/m3 najmanjša 343 kg/m3; to nakazuje na veliko variabilnost gostote na tem rastišču.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [A.
