- 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采后主要病原菌黑根霉、皮落青霉、链格孢、粉红聚端孢的菌丝生长抑制效应。结果表明：3种保鲜剂及其复合物对4种供试菌均有较强的抑制效果，且表现为浓度效应；其对4种供试菌的菌丝生长抑制率由大到小依次为壳聚糖-百里香酚、海藻酸钠-百里香酚、百里香酚、壳聚糖、海藻酸钠，复合物对菌丝生长的抑制效应比含有相同有效浓度的单体抑制效应有明显提高。
- Abstract:
- The inhibitory efficacy of chitosan，sodium alginate，thymol and their combinations on hyphal growth of major pathogenic fungi in post-harvest ‘Lingwuchangzao’，such as Rhizopus stolonifer，Penicillium crustosum，Alternaria alternate (Fr.) Keiss.and Trichoderma roseum (Pers.) were determined.The results showed that the three preservatives and their combinations had a strong inhibitory effect on the four experimental fungi and had a concentration effect.From the experiment that inhibition ratio of hyphal growth on the four experimental fungi in descending order would be chitosan-thymol，sodium alginate-thymol，thymol，chitosan，sodium alginate.Therefore，the inhibitory efficacy of chitosan，sodium alginate in combination with thymol on hyphal growth separately was significantly higher than that of them alone at the same effective concentration.
