摘要: 以西洋梨‘Conference'为材料诱导愈伤组织,采用L9(34)正交设计法,探讨各因子对‘Conference'梨愈伤组织诱导效果的影响。结果表明,各因素对愈伤组织诱导率的影响表现为TDZ浓度>外植体类型>IBA浓度,TDZ、IBA浓度对试验结果的影响呈显著水平(P<0.05),不同水平间也差异显著。最优组合为A1B3C3,即以茎段为外植体,培养基和植物生长调节剂组合为MS+2.0 mg/L TDZ + 0.5 mg/L IBA中暗培养35 d,诱导率可达100%。

Abstract: Pyrus communis L. ‘Conference' was used as material to induce callus, and L9(34) orthogonal design was used to explore the effects of various factors on callus induction of ‘Conference' pear.The results showed that the order of influence of each factor on callus induction: TDZ concentration > explants type > IBA concentration, and the influence of TDZ and IBA on the experimental results was significant (P<0.05), in addition, there were significant differences among different levels. A1B3C3 proved to be the best combination, stem segments were used as explants, MS+2.0 mg/L TDZ +0.5 mg/L IBA medium and dark culture for 35 days were adopted, and the induction rate was 100%.

Key words: Pyrus communis L. ‘Conference', tissue culture, callus, orthogonal design
