Odpornost lesa sibirskega macesna z naravnih rastišč in plantaž proti navlaževanju : diplomsko delo = Resistance to water uptake of wood of Siberian larch from natural sites and plantations : B. Sc. thesisKrznar, AljažZadnje čase se vse več macesnovega lesa uporablja v gradbeništvu, na primer za izgradnjo fasad, teras, balkonskih ograj. V Sloveniji je še posebej priljubljena uporaba sibirskega macesna. Zato nas je ... v nalogi zanimala odpornost naravno in plantažno gojenega sibirskega macesna (Larix sibirica) ter alpskega macesna (Larix decidua) proti navlaževanju. Poleg macesna smo v raziskavo vključili še smrekovino obdelano s pripravki za pospešeno sivenje lesa. Na vzorcih naravno in plantažno gojenega sibirskega macesna, alpskega macesna, navadne smrekovine in predhodno obdelane smrekovine smo izvajali različna testiranja odpornosti proti navlaževanju. Pri uravnovešanju vzorcev macesnov pri visoki zračni vlažnosti smo ugotovili, da je plantažno gojen sibirski macesen navzel največ vode, in se je najhitreje uravnovešal. Ob dolgotrajnem navzemu vode smo ugotovili, da se plantažno gojen in naravno rasel sibirski macesen navlažujeta enako hitro. Po končanih meritvah opazimo, da se najbolj navlaži plantažno gojen sibirski macesen, najmanj pa alpski macesen. Rezultati prikazujejo, da je plantažno gojen sibirski macesen bolj vodoodbojen kot alpski macesen ter sibirski macesen. Izračun predvidene življenjske dobe na podlagi zgoraj omenjenih testiranj kaže, da ima alpski macesen daljšo življenjsko dobo kot sibirski macesen iz naravnih rastišč ali pa plantažni macesen.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [A.
