Abstract

In this study, the physical properties (oven-dry density, basic density, volumetric shrinkage, and swelling) and structural components (cellulose, lignin, and extractives content) of three wild almond wood species from southwestern Iran, namely Amygdalus arabica, Amygdalus eburna, and Amygdalus scoparia, were investigated. Wild almond is a valuable wood species in the Zagros forests of Iran, but there is a lack of data on their wood properties. Three adult trees of each species were chosen, and samples were prepared from the breast height diameter to measure the focal properties. Results of analysis of variance (ANOVA) showed that the wood species had a significant effect on the wood density and volumetric shrinkage. Maximum oven-dry density and volumetric shrinkage of wood were identified in Amygdalus scoparia. The highest and lowest content of structural components were found in Amygdalus scoparia and Amygdalus arabica wood species, respectively. A deep understanding of the almond wood characteristics will provide a fresh insight into the relationship between the properties and conservation of these special, as well as applications of their wood.

Secondary title: Fizikalne in kemijske lastnosti lesa treh divjih vrst mandljevca, ki rastejo v gozdovih Zagrosa
Secondary abstract: V študiji so bile raziskane fizikalne lastnosti (gostota, osnovna gostota, prostorninsko krčenje in nabrekanje) in kemijska sestava (celuloza, lignin in ekstraktivne snovi) lesa treh divjih vrst mandljev, in sicer Amygdalus arabica, Amygdalus eburna in Amygdalus scoparia iz jugozahodnega Irana. Divji mandelj je dragocena drevesna vrsta v gozdovih Zagrosa v Iranu, podatki o lastnostih lesa pa so pomanjkljivi. Izbrana so bila tri sestojna drevesa vsake vrste, za merjenje omenjenih lastnosti pa so bili pripravljeni vzorci iz nivoja v prsni višini. Rezultati analize variance (ANOVA) so pokazali, da vrsta pomembno vpliva na gostoto lesa in prostorninsko krčenje. Največje vrednosti gostote absolutno suhega lesa in prostorninskega skrčka so bile ugotovljene pri vrsti Amygdalus scoparia. Najvišje in najnižje vsebnosti kemijskih komponent pa so bile ugotovljene pri lesnih vrstah Amygdalus scoparia in Amygdalus arabica. Poglobljeno razumevanje značilnosti mandljevega lesa bo omogočilo nov vpogled v povezavo med lastnostmi in ohranjanjem ter uporabo lesa raziskanih vrst.
