Radialne in vertikalne značilnosti jelovine kot heterokapilarnega sistema : diplomsko delo - visokošolski strokovni študij

Buh, Klemen (author), Gorišek, Željko (mentor), Oven, Primož (reviewer)

Na 3 izbranih drevesih jelke (Abies alba Mill.) s področja Snežnika smo določili višinske in radialne porazdelitve vlažnosti, gostote, vlažnosti točke nasičenja celičnih sten in volumenskih skrčkov. Vse proučevane lastnosti smo primerjalno vrednotili še med beljavo in jedrovino. Porazdelitve lesne vlažnosti na prečnih prerezih so potrdile tudi vizualno zaznano razporejenost mokrega srca, ki se je v večjih deležih pojavljal na bazi drevesa in v območju krošnje. Potrdili smo, da lahko mokro srce, ki otežuje sušilni postopek, ločujemo z vizualnim razvrščanjem in tako ločeno pripravljamo šarže za sušenje.

Abstract

Vertical and radial distribution of moisture, density, fibre saturation point moisture, and shrinkage in 3 selected fir trees (Abies alba Mill.) in the Snežnik area were determined. All studied properties were evaluated in correlation between sapwood and heartwood. Distribution of wood moisture on transverse sections confirmed visually detected the distribution of wetheart occurred in larger proportions in the base of the tree and in the crown area. We confirmed that the wetheart, which makes drying process more difficult, can be separated with visual classification and in this way separated batches of drying can be prepared.
