中文摘要 | 本研究之目的在探討10種闊葉樹材之抗蟻性,及其與木材比重,醇苯 抽出之關係,以臺灣二葉松作對照材,分木粉與木塊餵食家白蟻加以測試。木粉 試驗之結果顯示,白蟻死亡率與比重之相關不顯著(r2=0.35,F= 4.87,P>0.05), 卻與醇苯抽出物呈極顯著相關(r2=0.77,F=13.47,P< 0.01)。木塊試驗之重量損 失率比重呈極顯著相關(r2=0.66,F=17.33,P< 0.01),與醇苯抽出物亦呈顯著相 關(r2=0.52,F=9.89,P<0.05)。綜合言之,本實驗的10種樹材中以紅校欑最具抗 蟻性,白匏仔抗蟻性最為低劣。 |
英文摘要 | The purpose of this research is to investigate the termite resistance of ten native Taiwan hardwood species and its relationship with wood specific gravity and alcohol-benzene extractives. Wood meals and wood blocks of each species were fed to the termites. Taiwan red pine samples were served as controls. The results revealed that termite mortality was not significantly correlate with oven dry specific gravity (r2=0.35, F=4.87, P>0.05) but showed significant correlation with alcohol-benzene extractives of the wood (r2=0.77, F= 13.47, P<0.01). Weight loss of wood blocks after termite feeding was significantly correlate with oven dry specific gravity of the wood (r2=0.66, F=17.33, P<0.01) and alcohol- benzene extractive of the wood (r2=0.52, F=9.89, P<0.05). In conclusion, Cyclobalanopsis pachyloma was the most termite resistant tree species among the 10 tested hardwood species. while Sapium discolor and Mallotus paniculutus were the least resistant species. |
