华北棉铃疫病菌及蓖麻疫病菌的鉴定

作  者:
梁平彦
摘  要:
近年在华北地区普遍发生棉铃疫病和蓖麻叶果疫病。对于这两种疫病菌的形态和生理特性,按标准方法分剧进行了详细观察。把棉铃疫病菌鉴定为Phytophthora boehmeriae Sawada 的一个株系,并对它的寄主范围作了补充,在温度关系和有性生殖习性上它不同于已往西印度报导的棉铃上的 P.palmivoraBulter 和 P.parasitica Dastur。蓖麻疫病菌的性状与印度的典型 P.parasiticaDastur 相符合,与泽田兼吉在台湾描述的 P.ricini Sawada 和 P.formosanaSawada 两个新种只在寄主范围和孢子囊长宽比倒上稍有差异。

Two species of Phytophthora,one causing cotton boll blight and other causing leaf andcapsule blight of castor bean have been prevalent in North China in recent years.Detailedstudies have been made on their morphological and physiological characters supposed to be ofdiagnostic value.The cotton boll blight fungus is tentatively identified as a strain ofPhytophthora boehmeriae Sawada,although this species has not hitherto been known to infectcotton.The castor bean blight fungus is typical P.parasitica Dastur.
