亮耳菌杀线虫活性的稳定性

The Morbidity Stability of Different Lampteromyces japonicus Strains

采用平板测定方法测定了日本亮耳菌野生型菌株 (LAM1- 99,LAM 2 - 98)、驯化菌株 (LAM3,LAM 4)和退化型菌株 (LAM 5 )对腐生线虫和松材线虫的致病率 .结果表明这些菌株对不同线虫有不同的毒杀作用 .LAM 5菌株对松材线虫的致病效果高于野生型 ,而对腐生线虫的致病效果低于野生型 .从人工栽培的子实体中分离到的菌株 (LAM 3,LAM 4)能使菌株的性状向野生型恢复 .

Determined the morbidity of the five strains (wild type,tame type and degenerate type) of Lampteromyces japonicus on saprophytic nematode and Bursaphelenchus xylophilus .The results show the same species has different morbidity on different nematode.The morbidity of the degenerate type was higher than the wild type on Bursaphelenchus xylophilus and lower than the wild type on saprophytic nematode.The tame strains from the artificial cultivating fruit body possess activities similar to the wild types.
