摘要: 以两面针[Zanthoxylum nitidum (Roxb.)DC.]带芽嫩茎为外植体,研究了不同抗褐化剂对两面针组织培养中试管苗褐化的抑制效果。结果表明,在初代诱导培养基中添加1.0 g/L聚乙烯吡咯烷酮(PVP),外植体褐化程度轻,萌发率最高,为62.50%。3种添加抗褐化剂组合对试管苗抗褐化均起到一定抑制作用,添加PVP处理效果最理想,PVP浓度为1.0 g/L时,试管苗褐化率仅为11.67%,增殖系数为5.03,其次为活性炭(AC),抗坏血酸(维生素C)的抗褐化效果不明显。

Abstract: Tender stems were used as explants, to discuss the effects of different anti-browning agents on the browning of plantlets in tissue culture of Zanthoxylum nitidum. The results showed that when adding 1.0 g/L PVP in first culture medium, the explants were light browning, The highest budding rate was 62.50%. Three combinations of adding anti-browning agent played a role in inhibiting browning on test tube plantlet,The best result was to add PVP. The browning rate was 11.67% in the presence of PVP was 1.0 g/L, the multiplication coefficient was 5.03,followed by AC,the anti browning effect of Vc was not obvious.

Key words: Zanthoxylum nitidum (Roxb.)DC., stems, tissue culture, test tube plantlet, anti-browning
