摘　　要：本试验以马铃薯新品种达芋6号为试验材料,采用正交试验方法,研究培养基中不同种类、不同浓度激素对达芋6号马铃薯茎尖培养的影响。结果表明:NAA 0.05 mg/L+6-BA 0.5 mg/L+GA_(3)0.1 mg/L的处理成苗率、苗高优于其余处理;影响达芋6号成苗率及苗高的因素重要性排序为NAA浓度>GA3浓度>6-BA浓度;最有利于达芋6号成苗的激素水平为NAA 0.05 mg/L、GA_(3)0.1 mg/L、6-BA 1.0 mg/L;最有利于达芋6号苗高生长的激素水平为NAA 0.05 mg/L、GA_(3)0.1 mg/L、6-BA 0.1 mg/L。Taking a new potato variety Dayu 6 as the experimental material,this paper studied the effects of different types and concentrations of hormones in culture medium on stem-apex meristem culture of Dayu 6 by using orthogonal experiment as method.The results showed that the seedling formation rate and seedling height of NAA 0.05 mg/L+6-BA 0.5 mg/L+GA_(3)0.1 mg/L treatment were superior to other treatments.The importance order of the factors affecting the seedling formation rate and seedling height of Dayu 6 was NAA concentration>GA_(3)concentration>6-BA concentration.The most favorable hormone levels for the seedling formation of Dayu 6 were NAA 0.05 mg/L,GA_(3)0.1 mg/L,6-BA 1.0 mg/L.The most favorable hormone levels for the seedlings height of Dayu 6 were NAA 0.05 mg/L,GA_(3)0.1 mg/L,6-BA 0.1 mg/L.
