杉木茎尖诱导愈伤组织及植株再生研究

Study on Callus Induction and Plant Regeneration by Shoot Tip of Cunninghamia lanceolata

  • 摘要: 用杉木优良单株基部萌蘖条茎尖作为外植体进行组培快繁试验,结果表明:愈伤组织在改良MS+KT 02 mg/L+2,4-D 1.0 mg/L培养基上,外植体诱导率为86.7%;不定芽分化与增殖培养基为改良MS+KT 1.0 mg/L+IBA 05 mg/L,分化系数达3.42;芽苗培育约30d后,用1/2 MS+IBA 02 mg/L+ NAA 05 mg/L作生根培养基培养约25 d,生根率可达93%以上。生根苗移植到覆盖3cm厚黄心土的苗床上栽培,成活率可达90%以上。

     

    Abstract: The shoot tips sprouted from the trunk base of the superior individual plants of Cunninghamia lanceolata were applied as the explants to induce the callus on the improved medium MS+KT 02 mg/L+2,4-D 10 mg/LThe results showed that the induction rate reached 867%; the culture medium for differentiation and multiplication of adventitious bud was the improved MS+KT 10 mg/L+IBA 05mg/L,whose differentiation coefficient reached 342The culture medium for rooting to be applied 30 days later was the improved 1/2MS+IBA 02 mg/L+ NAA 05 mg/L, by which the rooting rate was 93% within 25 daysThe rooted seedlings were transplanted to the seedbed covered by 3 cm yellow soil for further cultivation, and the transplanting survival rate was over 90%.
