摘要
以麻竹(Dendrocalamus latiflorus Munro)组培增殖苗为材料,探索麻竹生根培养基及关键技术,筛选移栽介质。结果表明:诱导生根时,切取高为2~3 cm的丛芽最好,最佳生根培养基为1/2 MS+IBA 3.0 mg/L+NAA 0.8 mg/L,生根率达94.6%;麻竹生根苗移栽最佳的基质是椰糠,成活率可达90%,且幼苗生长健壮。
In order to study on tissue culture of Dendrocalamus latiflorus Munro, find out the key technology of rooting medium and select optimum medium for transplanting, the proliferation plantlets were used in this research. The results showed that the best rooting medium was containing MS+IBA 3.0 mg/L+NAA 0.8 mg/L when cut multiple shoot with 2~3cm high, the rooting rate was up to 94.6%. Coir Pith was the optimum medium for transplanting with the survival rate up to 90%, and seedling growth robust.
