摘要
研究了3种外源激素对白杜卫矛Euongmusmaackii硬枝扦插生根的影响,旨在为白杜卫矛的大量快速繁殖提供参考依据。结果表明:①白杜卫矛属皮部生根为主的综合生根类型:②3种外源激素均能促进插穗生根,以IBA总体效果最好,其次为NAA,ABT最差,但也优于对照;③不同质量浓度的外源激素对生根率的影响,以100mg·L-1IBA的效果最好,其次为200mg·L-1的IBA,200mg·L-1ABT的效果最差;④扦插60d后进行移栽,发现不同质量浓度的外源激素对白杜卫矛硬枝插穗的移栽成活率影响不显著。
The effects of three exogenous hormones on the rooting of cuttings of Euonymus maackii were studied to provide references to its rapid propagation in large volume. The results showed that (1) the rooting of E. maackii belonged to comprehensive rooting type which was mainly bark rooting; (2) 3 exogenous hormones could all contribute to rooting of cuttings, IBA having the best effect, NAA better and ABT worst; but they were better than control groups; (3) as for the effects of different concentrations of hormones on the rooting rate, 100 mg·L^(-1)IBA had the best effect, 200 mg·L^(-1) better, 200 mg·L^(-1) ABT worst; (4) the effects of different concentrations foreign hormones on the survival rate of its transplanted seedlings after 60 days'cutting were not significant.
