The tree compounds of each part in 5 needle-leaf trees were compared in the time of disease and health. Moreover, the effects of main tree compounds on mycelial growth of the causal fungi were investigated.1.The main bark compounds of Thujopsis dolabrata var. hondae were methyl esters of higher fatty acids in health, and abietinol and abieta-7,13-diene infected with the resinous stem canker.2.The main bark compounds of Chamaecyparis obtusa were the diterpene dimmer and higher fatty acids in health, and torulosal and ferruginol infected with the resinous stem canker. The wood compounds of C.obtusa infected with the resinous stem canker had terpenes with a more oxidized compounds compared to healthy specimens.3.The dominant compounds of the resin of C.obtusa were torulosol and cupressic acids, and those from C.lawsoniana were acetyl isocupressic acid and isocupressic acid. The former two diterpenes stimulated and the latter two suppressed the mycerial growth of causal fungus, Seiridium unicorne.4.Abieta-7,13-diene and acetylsandaracopimarinol were the characteristic compounds of the discolored wood of Cryptpmeria japonica by woodwasp.5.t-Communic acid in the C.obtusa bark will be a suitable substance to examine the process and the level of infection to the resinous stem canker.6.From the bark and the wood on the seiridium canker infected Chamaecyparis lawsoniana, antifungal terpenes such as totarol, nootkatin, nootkatone and 13-hydroxynootkatone were secreted. C.lawsoniana has a defense mechanisim based on terpenes.7.The dominant compounds of the resin from the seiridium canker infected Cupressocyparis leylandiiDallim were t-communic acid and torarol. These terpenes suppressed the mycelial growth of the causal fungus. C.leylandii has a defense mechanisim based on terpenes.

比较了5种针叶树在发病期和健康期各部位的树体化合物。此外，还研究了主要树皮化合物对病原真菌菌丝生长的影响。健康条件下的主要成分为高级脂肪酸甲酯，感染溃疡病的主要成分为松香醇和松香-7，13-二烯; 2.健康条件下的主要成分为二萜二聚体和高级脂肪酸，感染溃疡病的主要成分为torulosal和ferruginol。结果表明，感染溃疡病的钝叶青冈木材中萜烯类化合物的氧化程度高于健康木材。3.钝叶青冈木材中树脂的主要成分为球松醇和柏木酸，而劳森青冈木材中树脂的主要成分为乙酰异柏木酸和异柏木酸。前两种二萜类化合物对单角丝孢菌菌丝生长有促进作用，后两种二萜类化合物对单角丝孢菌菌丝生长有抑制作用。13-二烯和乙酰檀香海松醇是日本柳杉变色的特征化合物。6.从杜仲皮和杜仲叶中提取的柠檬酸，可以作为检测杜仲茎溃疡病发病过程和发病水平的物质。在感染锈病菌的杉木木材上，分泌出抗真菌萜类化合物，如：托塔洛尔、诺卡酮、诺卡酮和13-羟基诺卡酮。7.雷氏柏溃疡病树脂的主要成分为t-communic acid和torarol。这些萜烯抑制了致病真菌的菌丝生长。雷氏隐翅虫具有基于萜烯的防御机制。
