麦根腐平脐蠕孢引起新疆小麦根腐病的病原鉴定及其生物学特性分析
Identification and biological characterization of the root rot pathogen of wheat in Xinjiang caused by Bipolaris sorokiniana
摘要
Abstract
[Objective]To clarify the species and biological characteristics of root rot pathogens of wheat in Xinjiang,and to provide a scientific basis for the development of effective prevention and control measures.[Methods]This study used tissue isolation method to isolate and culture the pathogens in Xinjiang,selected representative strains from different regions for pathogenicity detection,combined with morphological and mo-lecular means to identify pathogens species,and used the growth rate method to determine their main biological characteristics.[Results]The representative strains(KS1-3,YL26,TC30 and ML26)were pathogenic;the pathogens were identified as Bipolaris sorokiniana(Sacc.)Shoemaker.The PDA medium was the most suit-able for mycelial growth,and it can grew at5-35℃and pH4-10.The optimum temperature was30℃,the optimum pH was 7,it was not sensitive to light,the best carbon sources were soluble starch and sucrose,and the best nitrogen sources were beef extract and peptone.[Conclusion]The pathogens of wheat root rot in Xin-jiang are Bipolaris sorokiniana,and its main biological characteristies are similar to most fungi,preferring tem-perature and light.关键词
