摘要:

为建立基于不定芽诱导的白花前胡高效再生体系,以野生白花前胡(Peucedanum praeruptorum Dunn)植株的茎尖组织为外植体,研究了不同激素及浓度对不定芽诱导和生根的影响,并通过形态学和细胞组织学观察了不定芽的超微结构。结果表明,不定芽诱导的最佳培养基为基本培养基(MS)+2.5 mg·L-1 6-苄基腺嘌呤(6-BA),不定芽的诱导率达到100%,不定芽的诱导倍数为7.3倍;最佳生根培养基为1/2MS+0.2 mg·L-1萘乙酸(NAA);最佳的移栽方式为待植株高3 cm以上,具有3~5条根,根系长达2 cm时,水培炼苗30 d,再移栽,移栽成活率达到100%。该体系为白花前胡的组织培养再生提供了新的途径,缩短了种苗繁育的周期。

Abstract:

To establish an efficient regeneration system of Peucedanum praeruptorum Dunn, the effects of different concentrations of hormones on the induction and rooting of adventitious buds were studied with the stem tip tissues of wild Peucedanum praeruptorum Dunn as explants. The results showed that the best medium for adventitious bud induction was MS+2.5 mg·L-1 6-BA, the induction rate reached 100%, and the multiplication rate of adventitious buds was 7.3 times. The best rooting medium was 1/2MS+0.2 mg·L-1 NAA. The best transplanting method was to transplant the seedlings to the seedbed after 30 days-hydroponic training of the plants which are higher than 3 cm, with 3 to 5 roots over 2 cm. This system provides a new way for tissue culture and regeneration of Peucedanum praeruptorum Dunn and shortens the period of seedling breeding.

Key words: Peucedanum praeruptorum Dunn, tissue culture, adventitious buds, regeneration system
