以冬枣为试材,从发病的冬枣上提取出病原菌,并进行分离纯化和鉴定,明确导致冬枣发病的病原菌主要为酵母菌和根霉菌。使用滤纸片法测定5种植物精油(罗勒精油、松红梅精油、薰衣草精油、红百里香精油、迷迭香精油)对酵母菌和根霉菌的抑菌活性,结果表明:红百里香精油对酵母菌和根霉菌都具有很强的抑制作用,抑菌圈直径为(22.43±0.06)mm和(23.48±0.06)mm。另外,采用试管浓度稀释法对5种植物精油的最低抑菌浓度(M IC )和最低杀菌浓度(M BC )进行了测定,得知红百里香精油对酵母菌的M IC值是0.625μL/m L ,M BC值是1.25μL/m L ;对根霉菌的M IC是0.625μL/m L , MBC值是2.5μL/mL。
以鼕棘為試材,從髮病的鼕棘上提取齣病原菌,併進行分離純化和鑒定,明確導緻鼕棘髮病的病原菌主要為酵母菌和根黴菌。使用濾紙片法測定5種植物精油(囉勒精油、鬆紅梅精油、薰衣草精油、紅百裏香精油、迷迭香精油)對酵母菌和根黴菌的抑菌活性,結果錶明:紅百裏香精油對酵母菌和根黴菌都具有很彊的抑製作用,抑菌圈直徑為(22.43±0.06)mm和(23.48±0.06)mm。另外,採用試管濃度稀釋法對5種植物精油的最低抑菌濃度(M IC )和最低殺菌濃度(M BC )進行瞭測定,得知紅百裏香精油對酵母菌的M IC值是0.625μL/m L ,M BC值是1.25μL/m L ;對根黴菌的M IC是0.625μL/m L , MBC值是2.5μL/mL。

Essential oils have effective inhibitory activity with natural ,green and safe characteristics and good prospects of developing antiseptic and freshening agent for fruits and vegetables .Firstly ,the pathogens isolated and purified and then identified that yeasts and rhizopus were the main pathogens .Secondly ,antibacterial activities of five essential oils (basil oils ,leptospermum scoparium oil ,lavender essential oil ,thymus serpyllum oil ,rosemary oil)for yeasts and rhizopus were determined by filter papers .The result showed that thymus serpyllum oil had effec‐tive inhibition for yeast and rhizopus .The determines of inhibitory zones of them were 22 .43 mm ± 0 .06 mm and 23 .48 mm ± 0 .06 mm .Finally ,the minimum inhibitory concentration (MIC) and minimum bactericidal concentra‐tion (MBC) of the five essential oils were determined by diluting tube concentration .The MIC of thymus serpyllum oil for yeast was 0 .625μL/mL ,and the MBC of thymus serpyllum oil for yeast was 1 .25μL /mL .The MIC of thy‐mus serpyllum oil for rhizopus was 0 .625 μL/mL and the MBC of thymus serpyllum oil for rhizopus was 2 .5 μL/mL .
