摘　　要：研究了壳聚糖、海藻酸钠、百里香酚及其复合物对灵武长枣(Zizphus jujube Mill cv.Lingwu changzao)采后主要病原真菌黑根霉、皮落青霉、链格孢、粉红聚端孢的抑菌效应,并确定其最低抑菌浓度。结果表明,3种抑菌剂及其复合物对4种供试菌均有不同程度的抑制作用;其对4种供试菌的最低抑菌浓度由小到大为壳-百复合物、海-百复合物、百里香酚、壳聚糖、海藻酸钠,复合物的抑菌效应比含有相同有效浓度的单体抑菌效应有明显提高。Chitosan,sodium alginate,thymol and their compounds were adopted to study their inhibitory efficacy on major pathogenic fungi in post-harvest Lingwu changzao(Zizphus jujube Mill cv.Lingwu changzao),such as Rhizopus stolonifer,Penicillium crustosum,Alternaria alternate(Fr.) Keiss.and Trichoderma roseum(Pers.) The minimal inhibitory concentration(MIC) was also tested.The results indicated that the three antimicrobial agents and their compounds had strong inhibitory effects on the four experimental fungi.The minimum inhibitory concentration on the four experimental fungi in descending order would be chitosan-thymol,sodium alginate-thymol,thymol,chitosan and sodium alginate.Therefore,the inhibitory efficacy of chitosan,sodium alginate in combination with thymol separately was significantly higher than that of them alone at the same effective concentration.
