马铃薯干腐病是马铃薯最重要的贮藏期病害之一, 现已成为马铃薯贮藏期烂窖的重要原因。实现病原菌的快速检测对病害诊断和科学防控具有重要的实践意义。本研究基于镰刀菌翻译延伸因子序列设计了一对检测接骨木镰刀菌 Fusarium sambucinum的特异引物Fs-F/Fs-R。该特异引物可从接骨木镰刀菌中获得309 bp的特异性扩增片段, 而其他种类镰刀菌及马铃薯重要病害病原菌中均无此片段, 说明该引物具...
为了解镰刀菌（Fusarium sp.）降解2，4，6-三氯苯酚（TCP）的因素影响规律，研究了温度、pH、外加碳源、氮源、氯离子及TCP浓度对其降解特性的影响，分析了其降解动力学与降解途径. 结论：镰刀菌能以TCP为唯一碳源和能源物质进行生长繁殖，TCP降解最适条件为：氮源NaNO3（0.2 g·L-1），30℃，pH=6～7. 外加碳源葡萄糖对降解TCP具有明显的抑制作用. 氯离子浓度低于0....
