摘要: 以钩藤(Uncaria rhynchophylla)幼嫩茎段为试验材料,系统研究了其外植体表面消毒、褐化控制、愈伤组织诱导与分化及不定根系诱导等组织培养技术。结果表明,钩藤外植体最适消毒方法为75%乙醇溶液浸泡30 s,无菌水冲洗3次,再用0.1% HgCl2溶液消毒8 min;添加7 mg/L的抗氧化物抗坏血酸(VC)可有效减轻外植体褐化;钩藤愈伤组织诱导的最佳培养基为MS+1.0 mg/L 6-BA+1.5 mg/L 2,4-D;最佳分化培养基为MS+0.2 mg/L NAA+2.5 mg/L 6-BA;不定根诱导最佳培养基为1/2 MS+1.5 mg/L NAA。

Abstract: Using the tender stem segments of Uncaria rhynchophylla as experimental materials, tissue culture techniques including explant surface sterilization, browning control, callus induction and differentiation, and adventitious root induction were systematically studied. The results showed that the optimal sterilization method for Uncaria rhynchophylla explants was soaking in 75% ethanol for 30 seconds, rinsing with sterile water 3 times, followed by treatment with 0.1% HgCl2 solution for 8 minutes. The addition of 7 mg/L ascorbic acid (VC) effectively reduced explant browning. The optimal medium for callus induction was MS+1.0 mg/L 6-BA+1.5 mg/L 2,4-D; the optimal differentiation medium was MS+0.2 mg/L NAA+2.5 mg/L 6-BA; and the optimal medium for adventitious root induction was 1/2 MS+1.5 mg/L NAA.

Key words: Uncaria rhynchophylla, callus induction, browning, rapid propagation system
