摘要
采用生长速率法测定了6种常见植物的无水乙醇粗提物和水粗提物对海棠花灰霉菌的抑制效果。结果表明,6种植物的水和无水乙醇粗提物对灰霉菌的抑制效果差别较大,其中马褂木和紫茎泽兰的抑菌效果最明显,而其他材料也有一定的抑菌效果。6种植物材料中除紫茎泽兰外无水乙醇粗提物的提取率均低于水粗提物,在不同浓度时6种植物的无水乙醇、水粗提物对灰霉菌的抑制作用均不同,但基本上表现为无水乙醇粗提物大于水粗提物。
The bacteriostatic effects of ethanol and aqueous crude extracts from six common plants on Botrytis cinerea of Malus spectabilis were studied.Results showed that,the control effect of ethanol and aqueous crude extracts from the six plants differed largely from each other,the most obvious control effects were found in the extracts of Liriodendron chinensis（Hemsl.） Sarg.and Ageratina adenophora,Apart from Ageratina adenophora,the extraction yield of ethanol extracts from other five plants was higher than that of aqueous extracts,different concentrations of ethanol and aqueous extracts had different bacteriostatic effects on Botrytis cinerea,the ethanol extracts of the six plants basically had higher bacteriostatic effects than aqueous extracts.
