摘要: 【目的】了解内蒙古地区胡萝卜茄病镰刀菌的生物学特性及药剂敏感性。【方法】对采自不同地区胡萝卜根腐病茄病镰刀菌TPL-1、WQ1、WQ2、DM、TX31、TX3-1的生长速度、产孢量进行测定,并且设置不同温度、pH值、碳源、氮源和药剂条件,测定各菌株在不同环境中的生长速度。【结果】正常生长条件下,菌株TX3-1生长速度最快,菌株TX31产孢量最少;在温度为5~40 ℃和pH值为5~11所有菌株均可生长,其适宜生长温度为25~30 ℃,最适pH值为7;适宜碳源依次为淀粉、麦芽糖;适宜氮源依次为蛋白胨、牛肉膏、硝酸钾;对甲基硫菌灵可湿性粉剂表现敏感。【结论】茄病镰刀菌适应范围较广,温暖、中性生态环境条件利于其快速生长繁殖,甲基硫菌灵可湿性粉剂可抑制其生长。

Abstract: 【Objective】To understand the biological characteristics and fungicide sensitivity of Fusarium solani on carrot in Inner Mongolia.【Methods】The growth rate and spore production of Fusarium solani in carrot TPL-1,WQ1,WQ2,DM,TX31,TX3-1 were determined in this experiment.Culturing in different temperature,pH,carbon source,nitrogen source and fungicide conditions to measure the colony diameter.【Results】Under normal growth conditions,strain TX3-1 had the fastest growth rate and the least sporulation amount of strain TX31.All strains could grow at a temperature of 5-40 ℃ and a pH of 5-11.The optimum growth temperature and pH were 25-30 ℃ and 7.The suitable carbon sources were starch and maltose.The appropriate nitrogen sources were peptone,beef extract and potassium nitrate in turn.Fusarium solani was sensitive to the wettable powder of thiophanate-methyl.【Conclusion】These strains had a wide range of adaptability. It was conducive to their rapid growth and reproduction under warm and neutral ecological environment conditions,and the wettable powder of thiophanate-methyl could inhibit their growth.
