Preliminary Study on Propagation Technique of Verbena bonariensis
摘要
Abstract
In order to enrich the reproduction method of Verbena bonariensis, the author treated the seeds with gibberellin ( GA) , treated the cuttings with ABT , and screened out the optimum medium formula for the tissue culture and rapid propagation of Verbena bonariensis.The results showed that:(1) GA could improve the seed vigor of Verbena bonariensis, and the germination in-dex and vitality index of 3 varieties in the treatment were higher than those in the control .There were differences in promoting effects of GA among different varieties .(2) ABT had no significant influence on the survival rate of Verbena bonariensis cuttings, but it had significant promotive effect on the root number and root length of cuttings , and the treatment with 500 mg/L ABT had the best pro-motive effect.(3) There were differences in optimum medium formula among various tissue -culture stages, the optimum medium for inducement was MS +6-BA 0.6 mg/L, the best medium for propagation was MS +6-BA 0.5 mg/L+NA A 0.1 mg/L, and the optimum medium for rooting was MS +IBA 0.4 mg/L.The highest rooting rate of Verbena bonariensis reached 93%, and the multiplication coefficient reached 4.2.关键词
