摘　　要：研究萘乙酸(NAA)、吲哚乙酸(IAA)、吲哚丁酸(IBA)不同浓度溶液速蘸插穗对郁李嫩枝扦插生根的影响。结果表明,未经植物生长调节剂处理的郁李嫩枝扦插的生根率仅10%左右,不同植物生长调节剂、不同浓度对郁李插穗生根都有显著的促进作用。其中,以IAA 5000 mg.L-1速蘸处理效果最好,生根率达到100%,平均生根量为25.75条。可在生产中推广应用。The cuttages and rooting of Prunus japonica twigs,which were treated with three kinds of hormones with different concentrations,were experimented.The results indicated that Prunus japonica softwood cuttings rooting rate was only about 10% without the plant growth regulator treatment,NAA,IAA and IBA had a remarkable effect on rooting of Prunus japonica,especially the treatments of 5000 mg·L-1 IAA had the rooting rate of 100%,and the mean rooting number was 25.75 resp.The study provided the reference for the popularization and utilization of Prunus japonica in production.
