摘要
烟草黑胫病是烟草(Nicotiana tabacum)的一种毁灭性病害。试验采集云南省昭通市的烟草黑胫病病株,采用组织分离法对病原菌进行分离、纯化,对其培养性状进行研究。结果表明,燕麦培养基适合烟草黑胫病菌(Phytophthora parasitica)的培养,菌丝生长旺盛;烟草黑胫病菌菌丝粗细不均匀,无隔膜,具有膨大体;孢子囊顶生,具脱落性,具1个或2个乳突。这些培养性状与前人研究结果相似,表明烟草黑胫病菌的培养性状较为稳定。
Tobacco Black Shank is a destructive disease of tobacco. The pathogen were obtained from diseased tobacco stem tissues collected in Zhaotong city, Yunnan province. Cultural characteristics of the isolates were studied by means of tissue isolation. The results showed that Oatmeal medium was suitable for Tobacco Black Shank. The mycelium were diverse in thick and number, hyphal swellings and without membrane. The sporangium was acrogenous and deciduous had one or two mastoid. The characteristics similar with previous researches indicated that the characteristics of the pathogen was stable.
