摘　　要：以四倍体酸枣（Ziziphus acidojujubaC.Y.Cheng et M.J.Liu）组培苗为试材,研究了生长调节剂及浓度、茎段类型、温度和刻伤对生根的影响。结果表明：采用1/2MS培养基添加IBA 1.5-2.0 mg/L适合四倍体酸枣组培苗生根;带茎尖茎段与不带茎尖茎段对生根没有显著影响;茎段带3片以上叶片有利于组培苗生根;适宜的生根温度为25-30℃;茎段基部刻伤与否对四倍体酸枣组培苗生根没有显著影响。The influencing factors,including growth regulators,types of stem segment,temperature and snicking,on rooting of the tetraploid sour jujube plantlets were studied.The results showed that it was preferable to add 1.5-2.0 mg/L IBA in 1/2 MS medium for rooting of the plantlets.There was no significant discrepancy for rooting rate between stem apex and stem segment.The appropriate rooting temperature was 25-30 ℃ and the appropriate leaf number on stem was more than three.There was no significant influence on rooting rate by snicking in stem base.
