中文摘要 | 為瞭解兩種加拿大進口及三種國內木材對家白蟻 (Coptotermes formosanus) 的天然抗性,與對三種木材腐朽菌,Fomitopsis pinicola, Ganoderma australe和 Gloeophyllum sp. 的耐腐性,將側柏、美國紅檜、台灣紅檜、台灣肖楠及台灣二葉松 (對照木材) 等五種試材切成木塊供抗白蟻及耐腐性測定。結果得知家白蟻取食五種天然試材的平均死亡率 (N = 5) 分別為側柏79.2 ± 4.2 %、美國紅檜 98.2± 1.8 %、台灣紅檜78.4 ± 3.9 %、台灣肖楠89.1 ± 4.1 %、台灣二葉松9.7 ± 2.2 %。五種試材經家白蟻取食後之平均重量損失率、分別為側柏5.0 ± 1.1%、美國紅檜1.3± 0.3 %、台灣紅檜5.1 ± 0.5 %、台灣肖楠3.0± 0.5 %、台灣二葉松29.1± 3.1 %。五種試材之蛀蝕外觀平均評分分別是側柏7.9、美國紅檜 9.4、台灣紅檜7.6、台灣肖楠8.9、台灣二葉松0.2。白蟻死亡率與重量損失呈顯著負相關 (r = -0.92, P < 0.01),與外觀評分呈顯著正相關 (r = 0.91, P < 0.01)。五種試材中,美國紅檜的抗蟻性最佳,台灣二葉松為抗蟻性最差的木材,其他木材介於兩者之間。耐腐性的測定結果顯示,二種褐腐菌 (F. pinicola和Gloeophyllum sp.) 造成台灣二葉松木材顯著重量損失,而對其它木材則沒有明顯的利用。白腐菌 (G. australe) 造成美國紅檜及台灣二葉松統計上顯著重量損失,但以重量損失率而言,白腐菌並沒有顯著消化供試所有木材。 |
英文摘要 | Two imported Canadian, Thuja plicata and Chamaecyparis nootkatensis, and 3 domestic wood materials, Chamaecyparis formosensis, Calocedrus formosana, and Pinus taiwanesis (control treatment), were tested according to ASTM D 3345-74 and D 2017-81 methods to determine their natural resistance to the Formosan termite (Coptotermes formosanus) and 3 wood rotting fungi (Fomitopsis pinicola, Ganoderma australe, and Gloeophyllum sp.), respectively. The results showed that the mortality of Formosan termites after feeding on different woods for 4 wk was 79.2± 4.2% for T. plicata, 98.2 ±1.8% for Ch. nootkatensis, 78.4 ± 3.9% for Ch. formosensis, 89.1 ± 4.1% for Ca. formosana and 9.7 ± 2.2% for P. taiwanesis. Average weight loss for blocks of each wood after the termites' feeding was 5.0 ± 1.1% for T. plicata, 1.3 ± 0.3% for Ch. nootkatensis, 5.1 ± 0.5% for Ch. formosensis, 3.0 ± 0.5% for Ca. formosana, and 29.1 ± 3.1% for P. taiwanesis. Average damage index of each wood was 7.9, for T. plicata, 9.4 for Ch. nootkatensis, 7.6 for Ch. formosensis, 8.9 for Ca. Formosana, and 0.2 for P. taiwanesis. Termite mortality was significantly correlated with the following parameters of the test wood blocks: weight loss (r = -0.92, P < 0.01) and damage index (r = 0.91, P < 0.01). Among the 5 test woods, Ch. nootkatensis had the best termite resistance, whereas P. taiwanesis was the least resistant, with the remaining species in between those two. For decay tests, the results showed that 2 brown rot fungi (F. pinicola and Gloeophyllum sp.) caused significant average weight loss in P. taiwanesis compared to the other woods. The white rot fungus, G. australe, caused significant average weight loss in C. nootkatensis and P. taiwanesis compared to other woods, but it did not significantly affect any other test woods in terms of average weight loss of wood. |
