1982—1988年从海南省10个县21个植胶场和云南省西双版纳、德宏州4个县9个植胶场采集橡胶树地上部的各种疫霉病害的样本,通过分离、提纯,共获得172株疫霉分离菌。经鉴定有以下5种疫霉:柑桔褐腐疫霉(Phytophthora citrophthora)、辣椒疫霉(P.capsici)、密氏疫霉(P.meadii)、寄生疫霉(P.parasitica)和棕榈疫霉(P.palmivora)。其中 P.citrophthora 有91株,占52.8%。其它4种疫霉顺次为45侏,占26.2%,19株,占11.1%,14株,占8.1%;3株,占1.8%。本文对这5种疫霉分别作了种的描述,其中密氏疫霉和寄生疫霉在中国橡胶树上是首次报道。
From 1982 to 1988, samples of various diseases of Phytophthora infestans were collected from 21 plasticized farms in 10 counties of Hainan Province and 9 plasticized farms in 4 counties of Xishuangbanna and Dehong prefectures in Yunnan Province. Through the separation and purification, 172 strains of Phytophthora isolated. The following five Phytophthora species were identified: Phytophthora citrophthora, P. capsici, P. meadii, P. parasitica and Palmettobacter P. palmivora. P.citrophthora 91 strains, accounting for 52.8%. The other four kinds of Phytophthora parasites were followed by 45 juveniles, accounting for 26.2% and 19 strains, accounting for 11.1% and 14 strains, accounting for 8.1% and 3 strains accounting for 1.8%. In this paper, we described the five Phytophthora species respectively, of which Phytophthora and Phytophthora infestans were first reported in Chinese rubber tree.
