| 摘 要： | 采用生长速率法和悬滴法测试了不同浓度苦参提取物、黄酮类化合物及生物碱对辣椒枯萎病的抑菌活性.结果表明:苦参提取物对辣椒枯萎菌菌丝生长和孢子萌发均有很强的抑制作用.在供试质量浓度40 g/L时,对辣椒枯萎菌菌丝生长、孢子萌发抑制率分别达到94.48％、89.01％；并且黄酮类化合物抑菌活性显著高于生物碱.

| Abstract: | The crude extracts of Sophora flavescens Ait and flavone and alkaloid were bioassayed by using growth rate and pendant-drop methods for antifungal activity of Capsicum blight at different concentrations.The results showed that crude extracts performed significant antifungal activity.The inhibition rate was 94.48% on mycelium growth and the inhibition rate on the spore germination was 89.01% as the concentration was 40 g/L.And the antifungal activity of flavone were more active than alkaloid. |
