This experiment was undertaken for the purpose of investigation of relative durability about thirty sorts of the korean native wood and nine sorts of the wood destroying fungi Polystictus versicolor, Irpex consors. Porial vaporaria, Merulius lacrymans, Schizophyllum commune, Trametes pini, Lenzites betulina, Paxillus panuoides by means of a loboratory methods.
The results obtained are ; (from the table 2 to 10)
1. By measuring the percentage of loss in weight with regard Polystictus versicolor, the sap wood contained in Juniperus chinensis was calculated at 18.2%, therefore it is much higher durability than any others and the sap wood contained in Pinus densiflora was measured at 44.10%, therefore it is much lower durability than any others.
2. By measuring the percentage of loss in weight with regard to Irpex consors, the heart wood contained in Butula schmidtii was calculated at 1.23%, therefore durability is very high and the heart wood contained in Quercns dentata was calculated at 26.79%, therefore durability is very low.
3. By measuring the percentage of lass in weight with regard to Lenzites betulina, the heart wood contained in Betula schmidtii was calculated at 5.33%, therefore it is much higher durability than any others and the sap wood with regard to Abies holophylla was measured at 45.48%, therefore durability is very low.
4. By measuring the percentage of loss in weight with regard to Poria vaporaria, the sap wood contained in Fraxinus rhynchophylla was calculated at 5.57%, therefore durability is very high and the sap wood contained in Paulownia coreana was calculated at 35.6%, therefore It is much lower durability than any others.
5. By measuring the percentage of loss in weight with regard to Merulius lacrymans, the heart wood contained in Castanea crenata was measured at 0.09% and in the next place, the heart wood contained in Abies holophylla calculated at 0.15% did not decay almost and the sap wood contained in Corpus controversa was measured at 32.88%, therfore it is lower durability than any others.
6. By measuring the percentage of loss in weight with regard to Schizophyllum commune, the sap wood captained in Juniperus chinensis was calculated at 1.09% therefore durability is very high and the sap wood contained in Populus deltoides was calculated at 36.87%, it is much lower durability than any others.
7. By measuring the percentage of loss in weight with regard to Trametes pini, the sap wood contained in Robinia pseudo-acacia was calculated at 1.33%, therefore durability is very high and the sap wood contained in Corpus controversa was calculated at 33.19%, it is much lower durability than any others.
8. By measuring the percentage of loss in weight with regard to Paxillus panuoides, the heart wood contained in Zelkova serrata was calculated at 1.73% therefore durability is very high and the sap wood contained in Populus calculated at 42.30%, therefore durability in very low.
9. By measuring the percentage of loss in weight with regard to Daedalea quercina, the heart wood contained in Castanea crenata was calculated at 0.92%, therefore durability is very high and the sap wood contained in Corpus controversa was calculated at 32.00% therefore durability is very low.
The above results are summarized as follows
1. Durability between the heart wood and the soft wood find that it is nonsignificant, while durability is higher heart wood than sap wood.
2. Special sorts including in the element like Castanea crenata, Robinia psedo-acacia, Juniperus chinensuis and heart wood like Betula schmiditii and Styrax obassia are highly durable and soft wood like Corpus controversa, Populus davidiana, Salix koreensis, Celtis jessensis are lowly durable in general.
3. Among the wood destroying fungi Paxillus panuoides is highly durable and as follows, Poria vaporariz, Lenzites betulina and the Daedalea quercina is less in general and Irpex consors, Merulius lacrymans are a middle degree.
