摘  要:
研究了不同培养方法、激素种类及质量浓度、抗生素种类及质量浓度对转基因烟草K326外植体分化的影响,并分别对其进行比较。结果表明:在培育转基因烟草K326抗性外植体的不同时期,依次选用最佳配方的烟草叶盘共培养培养基MS+1 mg/L 6-BA+0.1 mg/L NAA、烟草滤菌培养基MS+1 mg/L 6-BA+0.1 mg/L NAA+500 mg/L Carb、烟草筛选培养基MS+100 mg/LKan、烟草继代培养基MS+80 mg/L Kan+300 mg/L Carb、烟草生根培养基MS+0.1 mg/L NAA+300 mg/L Carb对转基因烟草外植体进行培育,可使转基因烟草外植体分化迅速,获得质量优良的试验材料,为进一步培育得到理想的转基因烟草K326完整植株奠定了工作基础。不同培养条件对外植体分化有较显著的影响,28℃、16 h光照最利于转基因烟草K326的外植体分化生长。

摘  要:
This research was to study the influence of different cultivation methods,hormones and antibiotics on explant differentiation of transgenic tobacco.There were five different culture media for the research,including MS+1 mg/L 6-BA+0.1 mg/L NAA for co-cultivation,MS+1 mg/L6-BA+0.1 mg/L NAA+500 mg/L Carb for sterilization cultivation,MS+100 mg/L Kan for screening,MS+80 mg/L Kan+300 mg/L Carb for subculture,and MS +0.1 mg/L NAA+300 mg/L Carb for root induction.With these mediums the explant of transgenic tobacco K326 could differentiate rapidly,which laid the basis for further cultivation of the whole plants of transgenic tobacco K326.
