Nastajanje lesa smreke v rastni sezoni 2009 : diplomsko delo - visokošolski strokovni študij = Wood formation in Norway spruce in growth period of 2009 : graduation thesis - higher professional studiesČerne, Andrej, 1984-V diplomski nalogi smo pri navadni smreki (Picea abies (L.) Karst.) raziskali začetek, konec in trajanje kambijeve produkcije ter nastajanje posameznih faz lesne branike na dveh rastiščih, na Panški ... reki (400 m n.m.v.) in Menini planini (1200 m n.m.v.). Na prvem rastišču smo analizirali odvzete vzorce iz šestih dreves, na drugem pa vzorce iz desetih dreves. Vzorci (mikro izvrtki) so bili odvzeti iz živih dreves z orodjem Trephor, v letu 2009, v tedenskih intervalih med 16. marcem in 28. septembrom na Panški reki ter med 24. aprilom in 25. septembrom na Menini planini. Po odvzemu smo jih s pomočjo tkivnega preparatorja prepojili s parafinom. Iz vzorcev smo na mikrotomnu izdelali rezine prečnega prereza, jih obarvali z barviloma safranin in astra modro, ter iz njih naredili mikroskopske preparate. Preparate smo analizirali s svetlobnim mikroskopom (Nikon Eclipse E800), s kamero za prikaz slike na računalniškem ekranu. Preparate smo pod mikroskopom analizirali (merjenje in štetje lesnih celic) vzdolž treh radialnih nizov. Pridobljene podatke smo vnašali v program Excel in jih statistično in grafično obdelali. Rezultati kažejo, da so začetki, konci ter trajanje posameznih faz pri nastanku lesne branike različni. Čas vegetacije se je pri drevesih na nižje ležeči Panški reki začel prej in končal kasneje kot pri drevesih na višje ležečem rastišču na Menini planini.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [A.
