本文作者以洋桔梗的组培苗为材料,研究了其茎节伸长和生根的一系列措施,设计了13种实验方案。结果表明,洋桔梗茎节伸长必须添加赤霉素,其浓度在0.5mg/L时较佳。生根培养基可为1/2MS+NAA0.6mg/L+BR1×10-5-5×10-5。
In this paper, the eustoma stems tissue culture seedlings as material, the stem elongation and rooting of a series of measures to design 13 kinds of experimental programs. The results showed that gibberellin must be added to the elongation of stem segments of Echinacea camphorata. The best concentration is 0.5mg / L. Rooting medium may be 1 / 2MS + NAA0.6mg / L + BR1 × 10-5-5 × 10-5.
