摘　　要：用生长速率法研究大蒜根乙酸乙酯浸提液对番茄晚疫病病原菌的抑制作用。结果表明:大蒜根乙酸乙酯浸提液各浓度均对番茄晚疫病病原菌有抑制作用,70%浓度处理的抑制作用最强,抑菌效果达到50%;高于70%浓度处理,随着浓度升高抑制作用逐渐减弱;低于70%处理随着浓度的降低抑制作用逐渐减弱;不同浓度处理随时间延长对番茄晚疫病病原菌的抑制作用均表现逐渐减弱的趋势。Using the growth rate method for the ethyl acetate extract of garlic root pathogen Phytophthora infestans based on a sense of inhibition were studied.The results showed that the ethyl acetate extract of garlic roots were expressed as the concentration of allelopathic inhibition,garlic root extract 70% ethyl acetate concentrations inhibited the strongest allelopathic allelopathic effect of 50% and high in 70% inhibitory concentration gradually decreased as the concentration,below the 70% inhibitory concentration decreased with the concentration gradually weakened with time and with different concentrations of tomato late blight pathogen showed allelopathic inhibition was gradually weakened trend.
