Effects of Seedling-cake Integrated with Arbuscular Mycorrhizal Fungi on Resistance of Bacterial Wilt in Pepper (Capsicum annuum L.)

育苗营养块结合菌根技术育苗对辣椒青枯病抗性的影响(英文)

[Objective] The aim was to investigated the effects of seedling-cake with AMF on resistance of pepper （Capsicum annuum L.） to bacterial wilt. [Methods] A pot experiment was conducted to evaluate the dynamics of mycorrhizal colonization, disease index, morbidity rate, control effect and several agronomic traits of mycorrhizal seedlings after inoculation with RS in two kinds of seeding-cakes with AMF. [Results] Two kinds of seedling-cakes formed steadily mycorrhizal colonization after inoculation, which enhanced disease-resistance and decreased morbidity rate and disease index in different degrees. What’s more, the performance of self-made seedling-cakes was obviously better than that of commercial seedling-cakes. [Conclusions] Self-made seedling-cakes with AMF have superior performance on bacterial wilt resistance of pepper, which should be made use of in other crops extensively.

[目的]调查研究营养块结合菌根技术育苗对辣椒青枯病抗性的影响。[方法]采用盆栽试验研究不同类型育苗营养块接种丛枝菌根真菌后的菌根辣椒幼苗,在接种青枯病菌后其菌根结构、病情指数、发病率、抗病效果动态变化及部分农艺性状变化。[结果]两种不同类型的营养块接种丛枝菌根真菌均可形成稳定的菌根结构,不同程度增加宿主植物抗病效果,降低其发病率和病情指数,且自制营养块明显优于商品营养块。[结论]自制营养块结合菌根技术育苗具有较好的青枯病防治效果,宜在其它作物试行推广应用。
