中文摘要 | 本研究係以臺灣櫸等11種闊葉樹材進行抗蟻性試驗,用臺灣二葉松作 為對照材,分木粉與木塊兩部份餵食之。木粉試驗之結果顯示木材比重、木材硬 度與家白蟻死亡率未有相關(p>0.05),但是木材醇苯抽出物則與家白蟻死亡率顯 著相關(r=0.67,p<0.05)。就木塊試驗而言,木材之比重、硬度與木材之咬食程度 呈反比例之關係。綜合而言,前者趨向試材之化學性質,而後者則為物理性質。 結果顯示:臺灣櫸、大頭茶及厚皮香3種最具抗蟻性,其次為烏來櫧、瑞芳楠、 山埔姜、大葉楠,而以單刺櫧、香桂、狗骨仔、白雞油為最弱。 |
英文摘要 | Taiwan zelkova (Zelkova formosana) and ten other native hardwood species of Taiwan were studied for their termite resistance proper-ties. Taiwan red pine (Pinus taiwanensis Hay.) samples were used as controls for comparison. Wood meals and wood blocks of each species were used as feed for the termites. The results of wood meals test indicate that wood specific gravity and hardness have no apparent correlation with termite mortalities (P>0.05). Wood extractive content, however, has significant correlation with termite mortalities (r=0.67, P< 0.05). As for the wood blocks test, the results indicate that wood specific gravity and hardness have inverse relationship with degrees of termite ingestion. In summation, the former indicates chemical resistance, and the latter physical deterrance, to termite invasion. Zelkova formosana, Gordonia axilaris and Ternstroemia gymnanthera were found to be most resistant to termite; Pasania uraiana, Machilus zuihoensis, Vitex quinata, and Machilus Kusanoi ranked next; whereas Castanopsis stipitata, Cinnamomum randaiensa, Diplospora dubia and Aphananthe aspera were least resistant. |
