Fizikalne lastnosti bukovine po žledolomu : diplomsko delo - visokošolski strokovni študij

Jakič, Jana (author), Straže, Aleš (mentor), Gorišek, Željko (reviewer)

Proučili smo vlažnost in gostoto lesa ter zunanje morfološke spremembe na različno prizadetih drevesih navadne bukve (Fagus sylvatica L.) ob koncu prve vegetacijske dobe po velikem žledolomu v Sloveniji v letu 2014. Potrdili smo povezanost med deležem še aktivnega koreninskega sistema in stopnjo porjavelosti (izsušenosti) krošnje dreves ter porazdelitvijo vlažnosti lesa v deblih dreves. Pri najbolj prizadetih drevesih smo v prevodnem zunanjem delu beljave potrdili padec vlažnosti lesa pod mejo naravne biološke odpornosti (u < 60 %). Po prvi vegetacijski dobi, nismo potrdili splošnega padca gostote lesa (in z njim povezanega poslabšanja mehanskih lastnosti), ki bi bil posledica okužbe in razkroja lesa z glivami

• Title: Physical properties of beech wood after sleet damage

Abstract

Moisture content and wood density of variously damaged uprooted European beech (Fagus sylvatica L.) trees were studied at the end of the first vegetation period after ice storm damage in Slovenian forests in 2014. The study confirmed significant correlation between the amount of active root system and necrosis of leaves and changed moisture content and its distribution in the trunks. The moisture content of wood below 60 % was confirmed in sapwood of extremely damaged trees, indicating diminished protection against wood destroying organisms. We could not confirm any reduction of wood density which would indicate deterioration of wood at the end of the first vegetation period after ice storm damage
