Abstract
Raziskali smo vpliv rdečega srca bukve na krčenje bukovega luščenega furnirja pri sušenju. Za izdelavo poskusnega furnirja smo izbrali 3 hlode bukve (Fagus sylvatica L.), ki so vsebovali rdeče srce. Ugotovili smo, da so skrčki furnirja iz poskusnih hlodov z rdečim srcem statistično značilno manjši kot skrčki furnirja iz zunanjih delov hlodov, kjer ni rdečega srca. Ravno tako smo ugotovili statistično značilno manjše skrčke furnirja, izdelanega iz notranjih delov testnih hlodov, ki ne vsebujejo rdečega srca, v primerjavi s furnirjem, izdelanim iz zunanjih delov istih hlodov. Raziskali smo še druge dejavnike, ki bi lahko vplivali na manjše krčenje furnirja, izdelanega iz notranjih delov hlodov; tenzijski les, gostoto lesa, gradient vlažnosti po prerezu debla, prisotnost juvenilnega lesa, delež ranega in kasnega lesa ter mesto vpetja hloda pri luščenju furnirja. Izmed vseh naštetih dejavnikov mesto vpetja najbolj vpliva na manjše krčenje furnirja, izdelanega iz osrednjih delov hloda.

Title:Influence of red heart on beech veneer quality and exploitation : graduation thesis - higher professional studies
Abstract:
Influence of red heart on beech peeled veneer shrinking was investigated. 3 logs of beech (Fagus sylvatica L.) with red heart and 3 logs without it were used for samples and tests. It was found out that the veneers with red heart shrank less than those without it. Veneers without red heart taken from interior parts of the logs shrank less than those taken from logsć periphery. Influence of tension wood, wood density, moisture gradient, juvenile wood, earlywood and latewood, centeringž clamping point at veneer peeling on beech peeled veneer shrinking were also investigated. Among all the factors mentioned above, centering/clamping point has the largest impact on smaller shrinking of veneer, made of interior parts of logs.

Keywords:beech (Fagus sylvatilca L.), peeled veneer, red heart, hydrothermal treatment
