| 摘要: |
| 1996年至1997年在广西沿海调查红树林植物病害时采集到桐花的煤污病病叶标本,用火棉胶贴片法取桐花叶面上的煤污菌斑显微观察,发现附在桐花叶面上的煤污菌有4种:番荔枝煤炱菌(Capnodium anona Pat.,其无性阶段为狭籽小箭壳孢(Microxyphium leptospermi Fischer.)、杜茎山星盾炱(Asterina maesae Pat.)、撒播烟霉(Fumago vagans Pers.)、盾壳霉(Conioth yrium sp.)。调查发现煤污病只发生在生长于河口内缘的桐花,其他地方的桐花没找到病株;几种煤污菌常常一起着生在一叶斑上;桐花煤污病具有明显的发病中心。 |

| Abstract: |
| Mangrove plant disease was investigated along the coast of Guangxi from 1996 to 1997, the sample leaves of Aegiceras corniculatum infected with sooty molds were gathered. The foliicolous sooty mold spot taken with pyroxylin cement was observed in microscope, the results showed that there were 4 species sooty molds attached to Aegiceras corniculatum leaves:Capnodium anona Pat (asexual phase:Microxyphium leptospermi Fischer.),Asterina maesae Pat., Fumago vagans Pers. and Coniothyrium sp. Sooty mold appeared only inside the river month of the mangrove area, not in the other area. More than one species attached to the same leaf spot, The number of the species gathered varies with the season and the influence. The disease has a clear center in the forest area infected with sooty mold. |
