摘要
竹节是提高竹子硬度和生长稳定性的重要组成部分。然而，人们对竹节如何影响工业用生物控制剂的抗性知之甚少。本研究旨在分析竹节和节间结构对地下白蚁的耐久性差异。在实验室（无选择和有选择）和地面实验中，研究了两种竹子，Giganthochloa scortechinii 和 Giganthochloa levis，以确定它们对 Coptotermes curvignathus 的抗性。从三个部分（底部、中部和顶部）分别取尺寸为 25 mm × 25 mm x 竹节厚度和 100 mm × 40 mm x 竹节厚度的样品，每个部分又细分为两个部分：节和节间。还测定了每个部分的水分含量。总体而言，G. scortechinii 比 G. levis 对 C. curvignathus 的抗性更强，节部比节间的抗性更强。所测试的两个竹种的抗性都是向节顶和节间增加的。在所有测试中，重量损失都是向顶端减少，而节部的重量损失比节间小。G. scortechinii 的目测值为 7.4 至 9.0（选择）和 7.5 至 9.2（无选择），而 G. levis 的目测值为 6.6 至 7.5（选择）和 6.5 至 7.4（无选择）。与节间相比，节的抗性高与各部分的解剖结构和在茎中的位置密切相关。
Understanding the termite resistance of Malaysian commercial bamboo for various applications
Bamboo nodes are an important component for increasing the hardness and stability of growth. However, little is known about how bamboo nodes affect resistance to biological control agents for industrial use. This study aims to analyze the durability differences between node and internode structures against subterranean termites. Two bamboo species, Giganthochloa scortechinii and Giganthochloa levis were investigated to determine their resistance against Coptotermes curvignathus in laboratory (no-choice and choice) and above-ground experiments. Samples measuring 25 mm × 25 mm x bamboo thickness and 100 mm × 40 mm x bamboo thickness were taken from the three portions (bottom, middle, and top) and each portion was subdivided into two parts: nodes and internodes. Moisture content is also determined for each portion and part. Overall, G. scortechinii is more resistant to C. curvignathus than G. levis, and the node section has greater resistance compared to the internode. The resistance of both bamboo species tested increases towards the top of the node and the internode. The weight loss decreases towards the top in all tests, while the nodes show less weight loss compared to the internodes. The visual determination value for G. scortechinii is 7.4 to 9.0 (choice) and 7.5 to 9.2 (no-choice), while 6.6 to 7.5 (choice) and 6.5 to 7.4 (no-choice) for G. levis. The high resistance of the nodes compared to the internodes is closely related to the anatomical structure of the individual parts and the position in the stem.
期刊介绍：
European Journal of Wood and Wood Products reports on original research and new developments in the field of wood and wood products and their biological, chemical, physical as well as mechanical and technological properties, processes and uses. Subjects range from roundwood to wood based products, composite materials and structural applications, with related jointing techniques. Moreover, it deals with wood as a chemical raw material, source of energy as well as with inter-disciplinary aspects of environmental assessment and international markets.
European Journal of Wood and Wood Products aims at promoting international scientific communication and transfer of new technologies from research into practice.
