摘要
桑黄真菌具有广泛的寄主范围，会导致不同树种不同树龄的棕色根腐病，无论它们最初的健康状况如何。该真菌广泛分布于东南亚、太平洋群岛和澳大利亚、中美洲和加勒比以及非洲的热带国家。自1988年在冲绳县石垣岛首次发现褐根腐病以来，冲绳县和鹿儿岛县的几个岛屿都报告了这种疾病，并对位于日本南部亚热带地区的琉球群岛的遮荫、防风、观赏和景观树木造成了严重问题。在此，我们根据我们的调查和以前发表的日本报道，报道了日本琉球群岛赤霉病的现状，包括该病的症状、发生、扩散、分布和寄主树种，病原菌的致病性和/或致病力，以及疾病管理。在调查的12个岛屿中的10个岛屿的不同地点，32个植物科的53个树种已经证实了棕色根腐病。在53个树种中，34个为日本首次记录的松材线虫寄主植物。该病主要发生在观光场所、公园、路旁、甘蔗地等农用地以及民居周围或其他与人类活动有关的地方的遮荫、观赏和防风树上。
Summary
The fungus Phellinus noxius has a broad host range and causes brown root rot in a variety of tree species of various ages, irrespective of their original health. The fungus is widely distributed in tropical countries of Southeast Asia, the Pacific Islands and Australia, Central America and Caribbean, and Africa. Since 1988, when brown root rot was first found on Ishigaki Island, Okinawa Prefecture, the disease has been reported on several islands in Okinawa and Kagoshima Prefectures, and it has been causing serious problems to shade, windbreak, ornamental and landscape trees in the Ryukyu Islands, located in the subtropical region of southern Japan. Here, we report on the current status of P. noxius-caused brown root rot in the Ryukyu Islands, Japan, including symptoms, occurrence, dispersal, distribution and host tree species of the disease, pathogenicity and/or virulence of the pathogen, and disease management based on our surveys and previously published reports from Japan. Brown root rot has been confirmed in 53 tree species from 32 plant families at different sites on 10 of the 12 islands surveyed. Among the 53 tree species, 34 were first recorded in Japan as host plants of P. noxius. The disease occurs mainly in shade, ornamental and windbreak trees at sightseeing places, parks, roadsides, agricultural land such as sugar cane fields, and around residences or other places associated with human activities.
