摘要
该文从ITS rDNA PCR RFLP方面揭示了杨树溃疡病菌与苹果干腐病菌、轮纹病菌、流胶病菌之间的划分分子依据 ,干腐病菌和轮纹病菌形成特征性带谱 ,干腐病菌和轮纹病菌均具有 12 0bp的特征性谱带 ,且轮纹病菌具有 2 10bp的特征性谱带 ;流胶病菌具有 2 10bp的特征性谱带而无 10 0bp的特征性谱带 ,杨树溃疡病菌既无 12 0bp ,也无 2 10bp的特征性带谱。
According to ITS-rDNA-PCR-RFLP analysis,the molecule classification foundation of poplar canker,apple canker,ring rot and gummosis pathogenic fungi was discovered.The pathogens of apple canker and ring rot both had the fragments of 120bp,and the advanced pathogen had the additive fragment of 210 bp.The pathogenic fungus of gummosis only had the special fragment of 210 bp while the poplar canker pathogen had none of these fragments.
