摘要: 以金叶龟甲冬青(Ilex crenata)幼嫩茎段为外植体,设置不同的腋芽诱导培养基、增殖培养基、壮苗及生根培养基进行对比研究,建立金叶龟甲冬青组培快繁体系。结果表明,采用培养基MS+ZT 0.5~1.0 mg/L+NAA 0.1 mg/L进行初代培养,腋芽诱导率达95%左右;利用培养基MS+ZT 0.5 mg/L+NAA 0.2 mg/L,丛生芽增殖系数高,幼苗生长健壮且色泽深绿;丛生芽接种于MS+ZT 0.5 mg/L+NAA 0.2 mg/L+蔗糖30 g/L培养基进行壮苗培养,幼苗高度可达4.9 cm,生长健壮,色泽深绿;适宜的生根培养基配方1/2 MS+IBA 0.1 mg/L+NAA 0.5 mg/L+活性炭3.0 g/L,生根率100%,根系生长健壮,色泽白色;经生根的试管苗移栽于园土(V)∶蛭石(V)∶泥炭(V)=2∶1∶1混合基质,加以合理管理,成活率可达95%。

Abstract: To establish an efficient tissue culture system for rapidly propagating, taking young stem section of Ilex crenata ender as explant, different bud-induction medium, proliferation medium, robust seedling medium and rooting medium were conducted. The results showed that the optimal bud-induction medium was MS+ZT 0.5~1.0 mg/L+NAA 0.1 mg/L and the induction rate of axillary bud was about 95%; The optimal medium for proliferation was MS+ZT 0.5 mg/L+NAA 0.2 mg/L,multiplication coefficient was high, seedling growth was strong with thick green; The optimal robust seedling medium was MS+ZT 0.5 mg/L+NAA 0.2 mg/L+sugar 30 g/L, the height of seedling reached 4.9 cm; The optimal rooting medium was 1/2 MS+IBA 0.1 mg/L+NAA 0.5 mg/L+active-carbon 3.0 g/L, and the roots were strong and white in color, the rooting rate was 100%; The survival percentage of plantlets could be up to 95% through transplanted in the substrate containing garden soil, vermiculite and peat (2∶1∶1,V/V/V).

Key words: Ilex crenata, tissue culture and rapid propagation, induction rate, rooting rate
