宁夏镰刀菌属(Fusarium Link)真菌的研究

摘要

[Objective] This paper was to identify fungi belonging to Fusarium Link. [Method] The species,distribution and the diseases caused by Fusarium Link in Ningxia Hui Autonomous Region were determined by the methods of field investigation .collection, isolated culture and identification. [Result] Nine species of fungi belonging to Fusarium Link were identified,including F. avenaceum,F. concolor,F. culmo-rutn ,F. graminearum ,F. moniliforme,F. nivale,F. oxysporum,F. solani and one unnamed species. They were distributed throughout Ningxia Hui Autonomous Region and caused more than 30 species of plant diseases. [ Conclusion ] Fusarium Link had many species in Ningxia Hui Autonomous Region without regional characteristics,and all of them were plant pathogens.%[目的]鉴定宁夏镰刀菌属真菌.[方法]采用实地考察、采集和分离培养鉴定的方法,研究了宁夏镰刀菌属真菌的种类、分布及其引起的植物病害.[结果]共鉴定出镰刀菌属真菌9种,分别为燕麦镰刀菌、同色镰刀菌、黄色镰刀菌、禾谷镰刀菌、串珠镰刀菌、雪腐镰刀菌、尖孢镰刀菌、茄类镰刀菌以及未定名镰刀菌属1种,它们分布于宁夏全区各地,引起30多种植物病害.[结论]宁夏镰刀菌属真菌种类较多,分布无地域特征,均为植物病原菌.
