摘　　要：[Objective] This research aimed to optimize continuously the highly efficient regeneration system of Anthurium andraeanum. [Method] The leaves and petioles of four A. andraeanum varieties were used as explants to investigate the differences in primary callus induction among different A. andraeanum varieties. [Result]The callus formation capacity of SAM and SST was stronger than that of SDM and SHG. Among the four varieties, the leaf regeneration capacity of SAM, SDM and SHG was stronger than the corresponding petiole regeneration capacity. However,the petiole regeneration capacity of SST was stronger. The optimum medium for petiole callus induction of SST was 1/2 MS ＋ TDZ 4.0 mg/L ＋ 2, 4-D 0.2 mg/L with induction rate of 87.5%; the optimum medium for leaf callus induction of SAM was 1/2 MS ＋ TDZ 2.0 mg/L ＋ 2, 4-D 0.2 mg/L with induction rate more than90%; the optimum medium for leaf callus induction of SDM and SHG was all 1/2MS ＋ ZT 2.0 mg/L ＋ 2, 4-D 0.2 mg/L with induction rates of 59.34% and 79.63%,respectively. [Conclusion] In addition to variety differences, the differences in differentiation ability among different types of calluses should be also taken into account in the establishment and optimization of tissue culture and rapid propagation technology system of A. andraeanum.[目的]不断优化红掌组培高效再生体系。[方法]以4个红掌盆栽品种的叶柄、叶片为外植体,研究红掌初代培养诱导愈伤组织的品种差异性。[结果]品种SAM、SST的愈伤组织形成能力强于SDM、SHG,其中品种SAM、SDM、SHG的叶片再生能力强于叶柄,而品种SST的叶柄再生能力较强。品种SST叶柄愈伤组织诱导的适宜培养基为1/2 MS+TDZ 4.0 mg/L+2,4-D 0.2 mg/L,出愈率可达87.5%;品种SAM叶片愈伤组织诱导的适宜培养基为1/2 MS+TDZ 2.0 mg/L+2,4-D 0.2 mg/L,出愈率高达90%;品种SDM、SHG叶片愈伤组织诱导适宜的培养基为1/2 MS+ZT 2.0 mg/L+2,4-D 0.2mg/L,出愈率分别可达59.34%和79.63%。[结论]在构建及优化红掌组培快繁技术体系时,除了品种因素以外,还需考虑不同外植体类型的分化能力差异。
