摘　　要：试验表明在试管繁殖条件下,豹斑竹芋的快速增殖宜采用改良的 MS 增养基,附加苄基腺嘌呤(BA)4 mg/1,萘乙酸(NAA)0. 5 mg/1,食糖40g/1. 培养中高光强(2. 5-5klx)比低光强(0. 5-0. 8kLx)有利于增殖.苗健壮,根系发达.培养温度以26℃±1℃最有利于芽苗培殖.试验找出了每瓶分注较适当的培养基数量和培养时间以提高出苗效率降低育苗成本.On the test tube propagation condition,experiment results indicate that modified Murashige and Skoog(MS)mediumadding 4 mg/l of 6-benzylamino purine(BA),0. 5mg/l of naphthaleneacetic acid(NAA)with 4% sucrose used forrapid propagation of Maranta was the most effective.This medium has been alone used through complete culture processfor both shoot multiplication and rooting stage.An average multiplication rate was achived as high as 3 to 3. 5 folds after6 weeks cultured with this medium.The optimum temperature used was 26±1℃.Higher light intensity(2. 5-5 klx)has improved the quality of plantlets and it more beneficial to propagation than the lower(0. 5-0. 8 Klx).The wholeplantlets harvested can be established either in a vermiculite or in a soil medium and survived easy.
