摘要：2011年6—8月份在浙江磐安地区采集到白术病害根、茎和叶片样本，经过室内分离试验得到4个根茎真菌分离物（分别记为R1～R4）与8个叶片真菌分离物（分别记为L1～L8）。依据科赫法则进行致病性测定，R1，R2为白术茎腐病病原菌，L3为白术叶斑病病原菌。通过形态学观察及分子鉴定方法确定R1为尖孢镰刀菌Fusariumoxysporura，R2为半裸镰刀菌Fusariumincarnatum，L3为长柄链格孢菌Alternarialongipes。
Diseased Atractylodes macrocephala were sampled in Panan, Zhejiang Province during June and August, 2011. Several fungus, 4 from stems （ R1 - R4 ） and 8 from leaves （ L1 - L8 ） , were isolated. The results determined by Koch＇s postulates indicated that R1 and R2 could cause stem-rot disease, while L3 could cause leaf spot on Atrac- tylodes macrocephala. Through morphological and molecular identification, R1, R2 and L3 were Fusarium oxyspo- rum, Fusarium incarnatum and Alternaria longipes, respectively.
