| 中文摘要: |
| 以中国古老月季原种‘月月红’(Rosa chinensis‘yueyuehong’)半木质化插穗为实验材料,采用扦插的方法,研究了不同生根基质、不同插穗位置及不同浓度3-吲哚丁酸(IBA)对其生根的影响。结果表明,IBA处理可促进插穗生根,提高生根率,生根数及根长,在以河沙作为基质的插穗中,IBA浓度在500μg/mL,已达到很好的生根效果。两种生根基质中,插穗的生根率、生根数及根长均高于河沙与田园土混配的基质,达差异极显著。在以河沙为基质中,插穗位置影响插穗的生根数及根长,以底端插穗位置最好,但对生根率的影响不大。基质与IBA之间的交互作用影响插穗的生根率、生根数及根长,基质与插穗位置之间的交互作用影响插穗的生根数,但对生根率及根长没有影响。‘月月红’插穗生根的最佳处理组合为:插穗位置为位于底端(下节),河沙作为扦插基质,IBA浓度为500μg/mL。 |

| Effects of different medias,cutting positions and auxin indolebutyric acid（IBA） solutions with different concentrations on the rooting of semi-hardwood cuttings of Rosa chinensis ＇yueyuehong＇ were investigated by the method of cutting propagation.The results suggested,rooting percentage,root number and root length were enhanced when cuttings were treated with IBA of different concentrations in a 0.03% solution of potassium hydroxide,the better rooting effects were found with 500 μg/mL in sand media.In two rooting media,rooting percentage,root number and root length appeared to be improved if cuttings were planted in sand alone as compared with sand：clay.Basal cuttings gave a better rooting response than apical and medial cuttings.It was found that the interaction between media and IBA concentration could enhance rooting percentage,root number and root length,the interaction between media and cutting position could enhance root number but not rooting percentage or root length.The best treatment for Rosa chinensis ＇yueyuehong＇ cuttings rooting was basal cuttings,sand media and 500 μg/mL IBA. |
