摘　　要：通过不同扦插基质、不同生根剂及其浓度与浸泡时间对滨梅嫩枝扦插生根效果影响的试验,结果表明,复合基质对滨梅扦插的效果优于单一基质,3种生根剂对滨梅插条生根率的影响顺序是ABT1>IBA>NAA,插条在生根剂中的浸泡时间对生根效果有显著影响。试验筛选出滨梅嫩枝扦插的最佳方案是:珍珠岩∶进口泥炭=1∶2的复合基质,用1 000mg·L-1 ABT1浸泡插条基部8min,扦插40d后的生根率平均达到89.1%。Effects of culturing factors, such as single and mixed substrates, plant growth regulators and soaking time on the rooting of softwood cuttings of beach plum （Prunus maritima） were investigated. The results showed that the mixed media were better than single medium to the rooting. The promotion effects on rooting rate of 3 plant growth regulators were in an order of ABT1〉IBA〉NAA. Soaking time exhibi- ted significant effects on rooting. The optimal method was selected as soaking the cuttings with 1 000 mg · L^-1 ABT1 for 8 min, then inserting into the mixed substrate of perlite and peat with the ratio of 1 ： 2, 40 days later the rooting rate could reach 89.1%.
