摘　　要：通过形态学和系统发育分析将柠檬桉幼叶和顶梢枯死病的病原菌鉴定为彼特氏桉座孢(Quambalaria pitereka)。生物学特性研究结果表明,环境因子(不同培养基、温度、光照、碳氮源和pH值)对病原菌菌丝生长和产孢影响差异显著。Based on morphological and phylogenetic analysis,the pathogen causing leaf and shoot blight disease on Corymbia citriodora was identified as Quambalaria pitereka.The research results of biological characteristics showed that environmental factors,including different media,temperature,light,carbon and nitrogen sources and pH,had significant effects on the mycelial growth and spore production of this pathogen.
