| 摘 要： | 采用生长速率法测定了柠檬草精油对梨树腐烂病菌、柑橘树脂病菌、柑橘黑腐病菌、西瓜炭疽病菌、甜瓜枯萎病菌、甜瓜叶斑病菌、甜瓜蔓枯病菌、蚕豆轮纹病菌的抑菌活性。结果表明，柠檬草精油对8种病原真菌都具有很好的抑菌活性，其EC50分别为308．0522、433．3196、399．7338、319．0103、366．8957、279．1261、270．7388和333．4956扯uL／L；用抑菌圈法测定了柠檬草精油对桃细菌性穿孔病菌的抑菌活性，结果表明，柠檬草精油对桃细菌性穿孔病菌也具有一定的抑菌活性，其最低抑茵浓度为500uL ／ L。

| Abstract: | By the myeelium growth rate methods,the inhibitory activities of Cymbopogon citratus essential oil was tested against Valsa ambiens （ Pers. ） Fr, Diaporthe citri （ Fazecett ） Wolf, Alternaria citri , Colletotrichum orbicaJare ,Fusariurn oxysporum f. sp. melonis,Alternaria alternate, DidymeZla bryoniae , and Cercospora Jabae . The results showed that C. citratus essential oil had good inhibition effects on 8 fungi and ECs0 were 308. 052 2,433. 319 6,399. 733 8,319. 010 3,366. 895 7,279. 126 1,270. 738 8 and 333. 495 6 uL/L respectively. In additions,inhibition zone experiment showed that C. citratus essential oil had good inhibition effect on Xanthornonas pruni （Smith） Dozen with 500 uL/L of minimum inhibitory concentration（MlC）. |
