本文着重讨论了中国黄瓜疫病菌由原来的P.melonis重新定名为P.drechsleri。对雪松上分离到的P.cinnamomi A_2交配型和P.drechsleri做了较详细的描述。上述各疫霉菌在我国均属首次报道。同时明确了异宗配合的疫霉属(Phytophthora)7个种(P.capsici,P.cinnamomi,P.melonis,P.drechsleri,P.palmivora,P.nicotianae和P.sinensis)47个菌株的交配型,并且指出P.drechsleriA_1和A_2两个交配型在南京具有同等优势。
This article focuses on the Chinese cucumber Phytophthora from the original P. melonis renamed P.drechsleri. P.cinnamomi A 2 mating type and P.drechsleri isolated from cedar were described in more detail. The above Phytophthora is the first report in our country. At the same time, it was clarified that 47 strains of Phytophthora were crossed with 7 strains of P. heterophylla (P. capsici, P. cinnamomi, P. melonis, P. drechsleri, P. palmivora, P. nicotianae and P. sinensis) Type, and pointed out that P.drechsleriA_1 and A_2 mating type have the same advantages in Nanjing.
