摘要
黑木耳及毛木耳的子实体易受粘菌侵害,并导致耳片在24～33小时内彻底溶解,因而在人工栽培中造成巨大经济损失。经调查观察及室内试验,证明病原粘菌在其营养生长阶段,能够分泌外酶以消化木耳而生活。与此同时,粘菌的原质体在段木及营养基质上扩展。在温度22～25℃,相对湿度95～100%,pH为5.5～6.5时,最适于粘菌侵染。其侵染过程及所出现的有机体的顺序均作了叙述,还提出控制这一侵染的某些措施。
The fruitbodies of Auricularia auricula and A. polytricha were attacked by the Myxomycetes and cause thoroughly lysis within 24～33 hr. thus result in giant economic loss in the production of A. auricula and A. polytricha by the artificial cultivation. Through the field observation and laboratory experiment had evidenced that the pathogen slime mold in their vegetative stage can feeding on the fruitbodies by the excretion of extraenzyme to digest it, at the same time the plasmodium of myxomycetes extened to the 'bed log' and nutrient substrate surface. As the temperature range 22～25℃, the relative humidity 95～100%, and the pH range 5.5～6.5 were optimal for the slime mold invasion. The invasion course and the succession of organisms occurred were described. The authors also provide with some measures for control this infection.
