Abstract

Kao osnovni cilj ovoga rada, istražen je grupni kemijski sastav crnog bora (Pinus nigra J.F. Arnold) poslije nastanka prizemnog niskog požara i visokog požara krošnje, na visini stabla od 0, 2 i 4m, te utjecaj na njegove makroskopske dijelove koru, bijel i srž. Dobiveni rezultati pokazali su značajne različitosti u grupnom kemijskom sastavu samo u kori između neopožarenog i opožarenog drva što je posljedica direktnog kontakta navedenih požara sa korom, dok kod ostalih makroskopskih dijelova drva tih različitosti nije bilo. Na temelju dobivenih rezultata grupnog kemijskog sastava, možemo zaključiti da osim kod kore, nema bitnih različitosti između neopožarenih i opožarenih makroskopskih dijelova drva crnoga bora, čime možemo pretpostaviti da opožareno drvo i dalje posjeduje sva svojstva za daljnju primjenu u mehaničkoj ili kemijskoj primjeni, što je vrlo pozitivno jer se radi o vrlo velikoj sirovinskoj bazi drvne biomase u Republici Hrvatskoj.

Abstract (english)

The basic objective of this paper was to investigate the group chemical composition of black pine (Pinus nigra Arn.) before and after the emergence of low ground fire and high fire of the treetops at the height of the trees of 0, 2 and 4 m, and the influence on its macroscopic parts of the bark, sapwood and the pith. The results obtained showed significant differences in the group chemical composition only in the bark between nonfired and fired wood resulting from the direct contact of the mentioned fire with the bark, while other macroscopic parts of the wood of these differences did not exist. Based on the results of the group chemical composition, we can conclude that there is no significant difference between nonfired and fired wood of black pine, which suggests that the fired wood still has all the properties for further application in mechanical or chemical application, which is very positive because it is a very large raw material source of wood biomass in the Croatia.
