摘要
对荞麦轮纹病病原菌草茎点霉(Phoma herbarum)进行了生物学特性研究,以期为今后荞麦轮纹病的综合防治提供理论依据。生物学特性研究结果表明,草茎点霉菌丝生长的最适温度为25℃,最适pH值为6。不同碳源和氮源对草茎点霉菌丝生长有显著影响;最适菌丝生长的碳源为葡萄糖,最适菌丝生长的氮源为蛋白胨、胱氨酸、牛肉浸膏和苯丙氨酸。草茎点霉菌丝在12h光暗交替条件下生长快,草茎点霉菌丝的致死温度为53℃,10min。
In this study, the biological characteristics of the pathogen （Phoma herbarum） of buckwheat ring rot were studied in order to provide a basis for the prevention and Control of the disease in future. The results showed that the optimum temperature and pH value for the Phoma herbarum mycelial growth were 25℃ and pH 6, respectively. Different carbon sources and nitrogen sources had significant effects on the mycelial growth. The optimum carbon source was glucose, and the optimum nitrogen sources were peptone, cystine, beef extract and phenylalanine. The 12-h illumination was beneficial to the growth of the mycelia. Lethal temperature of the myce- lia was at 53℃ for 10 min.
