ABT5号生根粉和预处理对黄山栝楼块根育苗的影响

以煤渣、棉籽壳、河沙等体积配比作育苗基质,对黄山栝楼块根进行不同预处理和浓度不同的ABT5号生根粉处理,清水处理作为对照,研究其育苗技术。通过试验,发现不同预处理间差异显著以高锰酸钾消毒剂浸泡效果为优,石灰水消毒剂浸泡效果为劣;是否使用生根粉育苗效果显著差异,ABT5号生根粉100mg/kg与50mg/kg、25mg/kg间的差异显著,50mg/kg与25mg/kg间差异不明显;不同预处理与生根粉浓度互作效应显著,优秀组合为高锰酸钾浸泡与50mg/kg生根粉、酒精乙醚浸泡与25mg/kg生根粉。

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

[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.
