[Objective] The purpose of the research was to discuss the conditions suitable for the cutting propagation of Jasminum sambac Aiton. [Method] With lignified and semi-lignified middle and lower segments of 1-year old mature branches of J. sambac as cuttings, the effects of different growth regulators and cutting substrates on the rooting of cuttings were researched. [Result] The root numbers of the cuttings treated with IAA, IBA and NAA and CK were 9.28, 13.53, 2.53 and 5.75 roots resp., their root lengths were 5.44, 6.57, 2.42 and 3.69 cm resp. and their rooting rates were 81.30%, 93.00%, 51.30% and 72.00% resp. The rooting rate of the cuttings treated with 500 mg/L IBA was highest, being 92.05%; their roots were most and their root number was 13.61 roots; their roots were longest and their root length was 6.72 cm. The root numbers of cuttings with river sand, vermiculite, river sand + garden soil and garden soil as substrates were 12.85, 11.59 , 9.35 and 0.44 roots resp., their root lengths were 8.54, 5.40, 4.64 and 0.29 cm resp. and their rooting rates were 96.57%, 86.40 %, 80.23 % and 7.35% resp. Taking production cost into consideration, river sand was relatively suitable cutting substrate. [Conclusion] The research supplied technical reference for the cutting propagation of J. sambac .%[目的]探讨适合茉莉花扦插繁殖的条件.[方法]以茉莉花一年生成熟枝条木质化或半木质化的中、下段为插穗,研究不同生长调节剂和不同扦插基质对插条生根的影响.[结果]用IAA、IBA和NAA处理的插条和对照的生根数分别为9.28、13.53、2.53和5.75 条,根长分别为5.44、6.57、2.42和3.69 cm,生根率分别为81.30%、93.00%、51.30%和72.00%.500 mg/L IBA处理的插条的生根率最高、生根最多、根长最长,分别为92.05%、13.61 条和6.72 cm.以河沙、蛭石、河沙+园土和园土作基质的插条的生根数分别为12.85、11.59、9.35和0.44条,根长分别为8.54、5.40、4.64和0.29 cm,生根率分别为96.57%、86.40%、80.23%和7.35%.结合生产成本考虑,河沙是比较适宜的扦插基质.[结论]该研究为茉莉花的扦插繁殖提供了技术参考.
