丁香枝枯病病原菌的分离和测定

Pathogen Isolation and Measurement of Branch-rot Disease of Syringa Oblate

通过对丁香患病标本进行分离、培养、纯化并保存菌种,得到病原菌后对病原菌及其分生孢子的形态进行观测。结果发现,经鉴定分离出来的病原菌属细交链孢霉(Alternaria tenuis Nees),并提出了防治方法,以期为进一步研究丁香枝枯病病原菌及有效防治丁香枝枯病的发生奠定基础。

The pathogens were gotten through isolation,cultivation,purification and preservation from specimens of Syringa oblate infected by dead arm. And then the morphology of pathogens and their conidia was observed. Results showed that the pathogens isolated from the identification were Alternaria tenuis Nees. Prevention and control method was put forward to lay the foundation for the study of branch-rot disease pathogens and effective prevention of dead arm of Syringa oblate.
