摘　　要：从对红松烂皮病发病林内的病害症状及病原菌形态的观察和测量.经人工接种的致病性测定试验结果,证明了引致辽宁省东部山区红松林烂皮病的病原菌是松生薄盘菌(Cenangium acicolum(Fuck.)Rehm)而不是铁锈薄盘菌(Cenangium ferruginosum Fr.)。这一结果仅是由抚顺地区人工红松林里调查、鉴定和人工接种的试验结果。至于该地区除这一种主要致病菌种外,是否尚有其它菌种,东北地区引致红松烂发病的病原菌种类除上述松生薄盘菌外,尚有那几种薄盘菌能引致红松烂皮病,以及不同地区引致该病害的优势菌种是否一致及其发生流行规律,经济有效的综合防治措施等,今后应继续进行广泛调查和深入研究,以达防病护林的经济效益和社会效益。Through accurate observation of the symptom and the measurement of the pathogenic fungi,particluarly according to the test results of artificial inoculation and research into the pathogen of Korean pine bark-rot in mountainous eastern Liaoning is Cenangium acicolum(Fuck.)Rehm rather than C.ferruginosum Ft.Our investigation was confined to Fushun region.Whether there are other fungi causing same disease or the same predominant fungus may follow different prevalence rule in different places,need further studies in order to control this disease thoroughly.
