摘要:

【目的】建立食用百合离体快繁体系。【方法】采用组织培养法,以食用百合N82和N136鳞片作为外植体,筛选外植体最优消毒灭菌方式,不定芽诱导、增殖、生根培养基和组培苗移栽基质。【结果】2个食用百合品种外植体消毒灭菌方式均以75%乙醇浸泡30 s后用3%NaClO溶液处理10 min。N82最优不定芽诱导培养基为0.5 mg/L 2,4-D+1.0 mg/L 6-BA+MS,诱导率为90.00%;最优增殖培养基为0.3 mg/L NAA+0.3 mg/L TDZ+MS,增殖系数为5.66;最优生根培养基为2.0 mg/L NAA+MS、2.0 mg/L IBA+MS和0.3 g/L AC+MS,生根率均为100%;最优组培苗移栽基质为草炭土:河沙=1:1,成活率为100%,幼苗长势良好。N136最优不定芽诱导培养基为1.0 mg/L NAA+1.0 mg/L 6-BA+MS,诱导率为93.30%;最优增殖培养基为0.5 mg/L NAA+0.2 mg/L TDZ+MS,增殖系数为5.86;最优生根培养基为0.5 g/L AC+MS,生根率为100%;最优组培苗移栽基质为草炭土:珍珠岩:河沙=1:1:1,成活率为100%。【结论】品种N82最优不定芽诱导培养基为0.5 mg/L 2,4-D+1.0 mg/L 6-BA+MS,最优增殖培养基为0.3 mg/L NAA+0.3 mg/L TDZ+MS,最优生根培养基为2.0 mg/L NAA+MS、2.0 mg/L IBA+MS和0.3 g/L AC+MS,最优组培苗移栽基质为草炭土:河沙=1:1。品种N136最优不定芽诱导培养基为1.0 mg/L NAA+1.0 mg/L 6-BA+MS,最优增殖培养基为0.5 mg/L NAA+0.2 mg/L TDZ+MS,最优生根培养基为0.5 g/L AC+MS,最优组培苗移栽基质为草炭土:珍珠岩:河沙=1:1:1。

Abstract:

【Objective】To establish in vitro rapid propagation system of edible lily.【Methods】Using tissue culture method with edible lily N82 and N136 bulbs as explants,the optimal disinfection and sterilization methods,the optimal adventitious bud induction,proliferation and rooting medium, and the best transplantation substrate for tissue culture seedlings were chosen.【Results】The disinfection and sterilization methods of the two edible lily cultivars were both immerse the explants in 75% ethanol for 30 s then treated with 3% NaClO solution for 10 min. The optimal adventitious bud induction medium for N82 was MS plus 0.5 mg/L 2,4-D and 1.0 mg/L 6-BA,with induction rate at 90.00%. The optimal proliferation medium was MS plus 0.3 mg/L NAA and 0.3 mg/L TDZ,with proliferation coefficient at 5.66. The optimal rooting medium was MS plus 2.0 mg/L NAA,MS plus 2.0 mg/L IBA and MS plus 0.3 g/L AC,all with rooting rate at 100%. The optimal transplantation substrate for tissue culture seedlings was 1:1 mixture of turf soil : river sand,with 100% survival rate and good seedlings growth. The optimal adventitious bud induction medium for N136 was MS plus 1.0 mg/L NAA and 1.0 mg/L 6-BA,with induction rate at 93.30%. The optimal proliferation medium was MS plus 0.5 mg/L NAA and 0.2 mg/L TDZ,with proliferation coefficient at 5.86. The optimal rooting medium was MS plus 0.5 g/L AC,with rooting rate at 100%. The optimal transplantation substrate for tissue culture seedlings was 1:1:1 mixture of turf soil:perlite:river sand,with 100% survival rate.【Conclusion】 For the cultivar N82,the optimal adventitious bud induction medium was MS plus 0.5 mg/L 2,4-D and 1.0 mg/L 6-BA,the optimal proliferation medium was MS plus 0.3 mg/L NAA and 0.3 mg/L TDZ,the optimal rooting medium was MS plus 2.0 mg/L NAA,MS plus 2.0 mg/L IBA and MS plus 0.3 g/L AC,and the optimal transplantation substrate for tissue culture seedlings was 1:1 mixture of turf soil : river sand. For the cultivar N136,the optimal adventitious bud induction medium was MS plus 1.0 mg/L NAA and 1.0 mg/L 6-BA,the optimal proliferation medium was MS plus 0.5 mg/L NAA and 0.2 mg/L TDZ,the optimal rooting medium was MS plus 0.5 g/L AC,and the optimal transplantation substrate for tissue culture seedlings was 1:1:1 mixture of turf soil:perlite:river sand.
