乳茄3种新病害病原菌鉴定

Identification of pathogenic fungi of three new diseases on Solanum mammosum

乳茄（Solanummammosum），又叫多头乳茄、五指茄、五代同堂、黄金果，为茄科茄属常绿小灌木。乳茄是一种珍贵的观果植物，原产美洲，近年引人我国广东、广西及云南种植，因其果色鲜艳，且观果期长，果形奇特，有“五子拜寿”和“五子登科”的寓意，在切花和盆栽花卉上广泛应用。

Three diseases on Solanum mammosum were identified according to the morphology and rDNA inter- nal transcribed spacer sequence of the pathogenic fungi. Pathogenicity test showed that black rot was caused by Alternaria altemata, anthracnose was caused by Colletotrichum gloeosporioides and Sclerotinia rot disease was caused by Sclerotinia sclerotiorum. This is the first report of three new diseases on Solanum mammosum.
