Abstract

Drvo ima ključnu ulogu u životu ljudi i koristi se od davnina do današnjih dana kao materijal za gradnju i ogrjev. Vrlo je važno poznavati mikro i makrostrukturu drva različitih svojti, jer one nam pomažu u determinaciji vrsta i rodova te direktno ili indirektno utječu na njegova fizikalna i mehanička svojstva.
U ovom radu istraživano je ukupno 29 komercijalnih vrsta drva; 7 vrsta četinjača te 22 vrste listača. Za potrebe ovog diplomskog rada napravljena je ksiloteka koja se sastoji od 29 daščica te njihovih mikroskopskih preparata izrađenih u tri karakteristična presjeka. Novonastale zbirke prve su takve na Biološkom odsjeku PMF-a i poslužit će kao materijal za učenje te kao komparativne zbirke kod determinacije uzoraka drva. Također se očekuje da zbirke posluže u budućnosti kao baza za nadopunjavanje novim vrstama.
U radu je načinjena također i fotodokumentacija svih mikroskopskih preparata te ksiloteke. Uz svaku drvenastu vrstu napisan je detaljan opis anatomske i morfološke građe drva te je vidljivo da postoje jasne razlike u građi drva između četinjača i listača, kao i među pojedinim vrstama/rodovima.
U diplomskom radu priložen je i izrađeni determinacijski ključ koji se koristi uz ksiloteku te omogućuje da se svaki uzorak determinira do razine vrste ili roda.

Abstract (english)

Wood plays a very important role in people's lives and has been used since ancient times as a building material and firewood. It is very important to know the micro and macrostructure of wood of different taxa, because it helps us to determine wood species/genera and it directly or indirectly affects wood’s physical and mechanical properties.
A total of 29 commercially important wood species were investigated in this paper; 7 conifers and 22 deciduous species. For the purpose of this thesis a collection of wood blocks (xylarium) was made. It consists of 29 wooden blocks together with microscopic slides for each wood species, which were done in three characteristic sections. These collections are the first of their kind at the Department of Biology, Faculty of Science and will serve as a learning material and as a comparative collections for the determination of wood samples. Collections are also expected to be supplemented with new species in the future.
The paper contains a photo documentation of all microscopic slides and wood blocks from xylarium. A detailed description of the anatomical and morphological structure of the wood has been written for each wood species, and it is evident that there are clear differences in the structure of conifers and deciduous trees, as well as among individual species/genera.
The paper also contains a determination key, which can be used for identification of each species or genus studied in this paper.
