落叶松癌肿病是世界驰名的森林病害之一,国外对该病的研究报告较多,但对病原菌的生物学特性研究报道较少。1975年,我国首次在带岭凉水林场人工落叶松林里发现,经调查,该病目前只分布在大小兴安岭地区。现已将此病列入林木病害检疫对象。我们在过去研究基础上,于1978、1982、1983年对病原菌的生物学特性进行了系统实验研究。一、关于Lachnellula属的变迁概况目前该属普遍使用Lachnellula属名,其
Larch cancer is one of the most famous forest diseases in the world. There are many reports about the disease in foreign countries, but there are few reports on the biological characteristics of the pathogens. In 1975, for the first time in our country, artificial larch forests were found in the Lianglingshui Forest Farm. After investigation, the disease is currently only distributed in the areas of the Greater Xing’an Mountains. Now the disease included in the quarantine object of forest diseases. Based on the previous studies, we systematically studied the biological characteristics of pathogenic bacteria in 1978, 1982 and 1983. First, on the evolution of Lachnellula genera At present, this genus commonly used Lachnellula genus, its
