摘要

為明瞭本省主要闊葉樹材之抗白蟻性，本研究以火燒柯等12種省產闊葉樹材進行抗白蟻性研究，乃以白蟻死亡率，重量損失率，外觀評估與木才比種，醇苯抽出之關係加以評估。結果顯示，白蟻死亡率與比重之相關不顯著(R^2=0.35)，與醇笨抽出物卻呈極顯著相(R^2=0.75)。重量損失率與比重呈顯著相關(R^2=0.48)，與醇苯抽出物呈極顯著相關(R^2=0.78)。十二種樹材中，以厚殼桂、火燒柯、水金京等3種樹材之抗蟻性最為優良，而以江某、山胡椒最為低劣。木材顏色與抗蟻性之關係及其應用亦在本文中加以討論。

This study investigated the terinite resistance of native Taiwan hardwood species. Termite mortality rates, weight losses of wood blocks after termite feeding, external feature changes, wood specific gravities and alcohol benzene extractive content of the wood served as parameters for determining the termite resistance of these wood. The results indicated that termite mortalities were not significantly correlated with oven-dry wood specific gravities (R^2=0.35), but showed significant correlation with the alcohol benzene extractive content of the wood (R^2=0.75). Weight losses of wood blocks after termite feeding were significantly correlated with oven-dry specific gravities of the wood (R^2=0.48) as well as alcohol benzene extractive oontent of the wood (R^2=0.78). In summation, Cryptocarya chinensis, Castanopsis hystrix, Wendlandia for mosana were found to be most resistant to termite; while Scheffleraoctapkylla, and Litsea cubeba were the least resistant. The relationship and application of wood coloration to its termite resistance were also discussed in the study.
