摘 要：
以中国科学院武汉植物园的宜昌黄杨嫩枝为材料,进行扦插繁殖试验,研究不同扦插基质及不同激素处理对嫩枝扦插生根率和生根质量的影响,以探讨影响宜昌黄杨扦插成活的因素,为宜昌黄杨快速育苗技术提供依据。结果表明:采用河沙为扦插基质可达最高生根率93.5%;以河沙为扦插基质,采用不同浓度激素处理,其中ABT200mg/L和IBA200mg/L溶液均能达到较高的生根率(92.2%以上)和较短的生根时间;综合考虑各种因素,以河沙为基质,用ABT200mg/L溶液浸泡3h处理抽穗,能获得理想的生根率和良好的生长状态。

摘 要：
For studying on the factors which influencing the cutting survival rate of Buxus ichangensis Hatusima and providing basis for the rapid seedling raising technology of it,the experiment of cuttage propagation was carried out to study the various cutting matrix and different hormone treatment on the softwood cuttings rooting rate and rooting quality,which conducted with Buxus ichangensis Hatusima twig collected from Wuhan Botany Garden,The Chinese Academy of Sciences as material.The results showed that with the river sand as cutting medium,it can obtain the highest rooting rate of 93.5%.With sand as the cutting matrix and with different concentrations of hormone treatment,both ABT 200 mg/L and IBA 200 mg/L solution were able to achieve a higher rooting rate(92.2% above)and shorter rooting time.Synthetically considered every kind of factors,the perfect rooting rate and good growth state could be got with river sand as medium and by treating cuttings with ABT 200 mg/L.
