摘要
以5年生厚荚相思(Acaciacrassicarpa)的萌芽茎段为外植体进行了组织培养的初步研究.结果表明:改良的MS+6 BA2.0mg/L+NAA0.2mg/L培养基能够较好地诱导芽的分化和增殖;适宜的继代增殖培养基为改良MS+6 BA1.5mg/L+NAA0.2mg/L;较为理想的生根培养基为1/2MS+IBA0.5mg/L,生根率达95.0%;生根苗的移栽基质以黄心土的移栽效果最好,移栽成活率达90.0%.
A tissue culture method is described for clonal multiplication of Acacia crassicarpa using nodal explants from the trees growing in the field. Results showed that the improved MS medium with 2.0 mg/L 6 BA and 0.2mg/L NAA was the optimum medium for induction and proliferation of bud clusters. The suitable culture medium for the generation continuing multiplication is the improved MS supplemented with 1.5mg/L 6 BA and NAA 0.2mg/L.The shoots rooted best on 1/2MS medium supplemented with 0.5 mg/L IBA. Plantlet survival after transfer to soil was 90.0%.
