| 摘 要： | 从我国南方香石竹主要生产基地采集萎蔫的香石竹病株,分离获得病菌经培养观察,致病性测定结果表明,我国香石竹种植地区主要致病菌是灰瓶霉菌Phialophroa cinerescens(Wr.) van Beyma]和尖镰孢石竹专化型Fusarium oxysporum Schl.Snyd.&Hans.f.sp.dianthi(Pril&Del.) Snyd.&Hans.]。商品扦插苗在无病地种植发病率为3.4%~8.0%;病地种植后发病率高达66.7%。在浙江省病株枯死主要发生在5月底到8月中旬,其中霉季枯死株占2/3以上。

| Abstract: | Routine studies on the pathogenicity determination of the withered carnations,collerted from 12 main production bases of carnation in the southern part of China,showed that Phialophroa cinerescen (Wr.) van Beyma and Fusarium oxysporum Schl.Snyd & Hans.f.sp. dianthi (Prill & Dell)Snyd.& Hans.were the main pathogens.When the commercial cuttings of carnation were planted in the pathogen-free soil,3.4%~8.0% of the plants were diseased,while planted in the infested soil 66.7% of the plants were infecteds. The incidence mainly, happend from the end of May to the mid August and more than 2/3 of them occurred in the monsoon season. |
