摘要
以台杨3号茎段和叶片为外植体材料,建立离体再生体系。结果表明:茎段在0.15%HgCl_2溶液中处理10min,污染率为23.3%,出芽率达75.3%,在MS+BA 0.3mg·L^(-1)+NAA 0.1mg·L^(-1)培养基中诱导不定芽的效果较好,平均分化率77.8%;叶片分化培养基为MS+BA 0.5mg·L^(-1)+NAA 0.2mg·L^(-1)+KT 0.2mg·L^(-1)+Ad 40mg·L^(-1),分化率可达87.7%;MS+BA 0.5mg·L^(-1)+KT 0.3mg·L^(-1)+NAA 0.2mg·L^(-1)培养基增殖效果较好;1/2MS+NAA 0.2mg·L^(-1)+CCC 0.5mg·L^(-1)为生根、壮苗培养基,生根率100%。
A regeneration protocol was established using the stems and leaves of fast-growing Taiwan Poplar 3 as explants.The selected disinfection time for the stems was 10 min in a 0.15% HgCl2 solution to result in an infection rate of 23.3% and a budding rate of 75.3%.The optimized medium for generating adventitious buds was MS+BA0.3 mg· L^-1+ NAA 0.1 mg· L^-1 to reach an average differentiation rate of 77.88%;that for the leaf differentiation,MS+BA 0.5 mg·L^-1+NAA 0.2 mg·L^-1+KT 0.2 mg·L^-1+adenine 40 mg·L^-1 with a differentiation rate of 87.7%;that for the proliferation,MS+BA 0.5 mg·L^-1+KT 0.3 mg·L^-1+NAA 0.2 mg·L^-1;and that for rooting,1/2 MS+NAA 0.2 mg·L^-1+CCC 0.5 mg·L^-1 with a 100% rooting rate.
