Spremljanje kakovosti in vrednosti hlodovine s konvencionalnimi, dendrokronološkimi in nedestruktivnimi metodami [Elektronski vir] = Monitoring the quality and value of European oak logs using conventional, dendrochronological and non-destructive methodsStraže, Aleš ; Novak, Klemen, 1979- ; Žigon, JureV raziskavo smo vključili hrastovo hlodovino (Quercus robur, Quercus petraea) s 15. dražbe vrednejših sortimentov okroglega lesa v Slovenj Gradcu v letu 2021. Naključno smo izbrali 78 od 1318 ... licitiranih hlodov in jih skladno z veljavnim Pravilnikom o merjenju (2017) vizualno razvrstili po kakovosti (A, B, C). Vzporedno smo dendrokronološko analizirali priraščanje lesa ter z metodo frekvenčnega odziva pri vzdolžnem vzbujanju še akustične lastnosti hlodovine. Najkvalitetnejša hlodovina je bila večjih premerov, z več in povprečno širšimi branikami. Potrdili smo povezavo med vizualno določeno kakovostjo in doseženo ceno hlodovine. Hitrost vzdolžnega nihanja (v) in relativna učinkovitost akustične pretvorbe (RACE) sta bili s kakovostjo in ceno hlodovine pozitivno povezani. Frekvenčni spektri pri hlodovini nižje kakovosti odstopajo od teoretičnih. Raziskava je potrdila možnost uporabe nedestruktivnih akustičnih metod za oceno kakovosti hrastove hlodovine.Source: Les [Elektronski vir] = Wood. - ISSN 2590-9932 (Let. 72, št. 1, 2023, str. 71-80)Type of material - e-article ; adult, seriousPublish date - 2023Language - englishCOBISS.SI-ID - 159001091
