Obarvanje javorjevine z glivami modrivkami in plesnimi : diplomski projekt = Spalting of acer wood with blue stain and mould fungi : B. Sc. thesisŠenekar, SašoV preteklosti so barvne spremembe lesa, ki so bile posledica okužbe z glivami, veljale za napake lesa, danes pa so ponekod zaželene. Namen raziskave je preučiti barvne spremembe in izgubo mase lesa ... javorja, ki so posledica okužbe lesa z glivami. Uporabil smo kombinacijo gliv bele trohnobe in dve glivi plesni. Manjšim vzorcem, ki so bili izdelani iz lesa poljskega javorja % maklen, sem numerično določil barvni ton po sistemu CIELAB, pred in po štiri oziroma osem tedenski izpostavitvi. Sočasno smo večje kose lesa izpostavili enakim kombinacijam gliv za osem tednov. Na osnovi rezultatov smo ugotovili, da smo priča barvnim spremembam na lesu izpostavljenim pri plesnim kakor tudi glivam bele trohnobe. Glive plesni so izrazito spremenile barvni ton lesa, hkrati so glive bele trohnobe tvorile conske linije. Rezultati izgube mase so kazali dobre in slabe znake. Medtem ko je pri plesnih prišlo do manjših izgub mase, je pri glivah bele trohnobe prišlo do velikih padcev v masi, za približno 20 %. Velike izgube mase pomenijo izgube v mehanskih lastnostih in s tem padec vrednosti. Večji vzorci so pred odstranitvijo zgornjega sloja kazali optimistične rezultate, vendar po odstranitvi so bile vidne le manjše barvne spremembe, ki niso dosegale pričakovanj. Na podlagi teh ugotovitev sklepam, da pri večjih vzorcih potrebujemo več časa za zadovoljive barvne spremembe.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [S.
