Application the method of use coriolus vesicolor and Glocophyllum trabocum to inoculate 42 heartwood appraises their natural rot—resisting abilites of heartwood of trees in northern China. The rot—resisting ability has been divided into 4 grades (Ⅰ—Ⅳ from strong to weak). The result shows Ⅰ grade has 8 species, Ⅱ grade 14 species, Ⅲ grade species 8 species, Ⅳ grade 12 species.             本文通过将彩绒(艹卓)盖菌和密粘褶菌接种42种树木心材的方法评价了我国北方主要树种的天然耐腐性。本试验将耐腐性分成Ⅰ～Ⅳ4个等级(由强到弱)。试验结果表明,Ⅰ级为8种。Ⅱ级为14种。Ⅲ级为8种,Ⅳ级为12种。 文摘来源          According to biological toxic test. the extraction. separation and structural identification of the active antifungal substrates in the Albizzia kalkora (ROXB)PRAIN heartwood was conducted. Results prove primarily that the natural rotproofness of Albizzia kalkora (ROXB) PRAIN heartwood comes mainly from medicarpin. trans-farnesol and so on.             以生物毒性试验为依据，对山槐心材中的有效抗菌成份进行了提取、分离及结构鉴定．初步证明了山槐心材的天然耐腐性主要来由于麦地卡品、反—金合欢醇等物质。 文摘来源          In recent years, eucalyptus plantation is being developed very quickly in southern China and became an important raw material for industrial utilization. But it is necessary to determine the natural decay resistance, durability and ability of anti attack to pests.
