摘　　要：采用红颜、点雪、章姬、随珠4种草莓匍匐茎茎尖作为外植体,研究培养基类型、细胞分裂素种类和浓度、生长素种类和浓度对4种草莓茎尖萌发、腋芽增值、生根的影响。结果表明:MS+BA0.5mg/L是4种草莓最适萌发的培养基,萌发率分别为50%、75%、50%、62%;MS+BA0.5mg/L+NAA0.1mg/L是红颜、点雪草莓最适增值培养基,增值倍数分别达到5.1、6.0。MS+BA1.0mg/L+NAA0.1mg/L是章姬、随珠草莓最适增值培养基,增值倍数分别为5.8、4.3;IBA0.mg/L+1/2MS是4种草莓最适生根培养基,生根率分别是100%、91.6%、100%、100%,生根数分别为8.2、10.5、8.7、5.5。The shoot tip of four kinds of strawberry were used as explants,including Hongyan dianxue Zhangji Suizhu,on shoot tip germination、axillary bud multiplication、taking root were studied. The results were as follows： the optimum medium for shoot tip germination of four strawberry were MS ＋ BA0. 5mg L,germination rates respectively were 50%,75%,50%,62%; The optimum axillary bud multiplication medium was MS ＋ BA0. 5mg / L ＋ NAA0. 1mg / L,including hongyan Dianxue,the highest axillary bud proliferation times respectively were 5. 1、6. 0. the Zhangji and Suizhu strawberry of the optimum axillary bud multiplication medium was MS ＋BA1. 0mg / L ＋ NAA0. 1mg / L,the highest axillary bud proliferation times respectively were 5. 8、4. 3. The optimum medium for taking root of four strawberry was IBA0. 3mg / L ＋ 1 /2MS,the rooting rate respectively were 100% 、91. 6% 、100% 、100%,the rooting number respectively were 8. 2、10. 5、8. 7、5. 5.
