摘要
以细尾桉为试材进行离体快繁研究。结果表明:通过二步消毒法,0.1%升汞能有效控制褐变,提高芽苗成活率;芽苗增殖较适宜的培养基为MS+0.5 mg.L-1BA+0.2 mg.L-1NAA;生根较适宜的培养基为1/2 MS+0.2 mg.L-1NAA,生根率达96%以上。
The Eucalyptus urophylla × E. tereticornis cultivar was used for in vitro rapid propagation in this study. The result showed that two-step sterilizing by 0.1% mercuric chloride was available for browning control, which also improved the rate of shoot survival. The optimum media for shoot propagation was MS ＋0.5 mg·L^-1 BA ＋0.2 mg·L^-1 NAA. The rooting medium 1/2 MS supplemented with 0.2 mg·L^-1 NAA resulted in rooting rate of more than 96%.
