阿魏氯仿提取物对7种玉米病害的离体抑菌活性比较

The Antibacterial Activity of Chloroform Extracts of Ferula on Diseases in Maize in Vitro

采用生长速率法和孢子萌发法测定了阿魏氯仿提取物对引起玉米病害的7种病原菌(小斑病菌、弯孢霉叶斑病菌、链格孢叶斑病病菌、圆斑病菌、顶腐病菌、青枯病菌和瘤黑粉病菌)的菌丝生长和孢子萌发的影响。结果表明,对于同一种病原菌来说,阿魏氯仿提取物对其菌丝生长的抑制效果好于对其孢子萌发的抑制效果;对顶腐病菌菌丝生长的抑制效果最好,EC50只有46.66 mg/L;可引起大中型分生孢子畸形。

The ferula（ Ferula sinkiangensis ） is a traditional herbal medicine in China. Its main active components are volatile oils and gums. The effects of chloroform extracts of ferula on hyphae growth and spore germination of seven pathogens （ Bipolaris maydis , Curvularia lunata , Alternaria tenuis , Bipolaris carbonum, Fusarium moniliforme , Fusarium spp, Ustsilago maydis ） in maize were studied in this article. The growth rate method and spores germination method were used to determine the activities. The results showed that the chloroform extracts of ferula has significant antibacterial activity on tested pathogens, while effects on spores germination were higher than that on hyphae growth. The effect on hyphae growth of Fusarium moniliforme was better, EC50 = 46.66 mg/L. The chloroform extracts of ferula can beget abnormality of big and medium conidiophores.
