选取4种观赏芳香植物进行人工繁殖试验以提高繁殖效率。播种试验中，深山含笑种子以50℃ GA3300 mg·L-1溶液人工催芽效果最好，发芽率、发芽势分别比去皮种子增加22.7%和17.3%；单叶蔓荆种子以50℃ GA31.0 g·L-1溶液浸泡催芽效果最好，发芽率、发芽势分别比对照增加46.7%和25.4%。以植物生长调节剂预处理扦插枝条，栀子插穗用NAA 100 mg·L-1+ IBA 100 mg·L-1预处理，生根率、平均生根数、成活率最高，其生根率和成活率分别比对照增加18.7%和15.8%，平均生根数比对照提高58.9%；络石插穗用NAA 200 mg·L-1＋IBA 200 mg·L-1预处理的生根效果最好，生根率、成活率分别比对照增加24.5%和19.1%，平均生根数比对照提高66.7%。

To play the effects of native fragrant plants of Xiamen on perfuming environment, four kinds of ornamental fragrant plant were tested on artificial breeding for improving their reproductive efficiency. In accelerating germination experiment of Michelia maudiae, it worked best that seeds were soaked with 300 mg·L-1 GA3 at 50℃, the germination rate and germination potentiality were increased by 22.7% and 17.3%, respectively,as compared to that of peeled seeds. The seed ofVitex trifoliavar. simplicifoliawhich was accelerated germination with 1.0 g·L-1 GA3 at 50℃ had a best result, germination rate and germination potentiality were increased by 46.7% and 25.4%, respectively, than the control. In cuttage test the cuttings were pretreatmented with some plant growth regulators, and observed rooting rate, survival rate and average root number per cutting. Increase rates of three indexes were highest when Gardenia jasminoidescuttings pretreatmented with the solution of 100 mg·L-1 NAA and 100 mg·L-1IBA, rooting rate and survival rate were increased by 18.7% and 15.8%, respectively, comparing with the control, and the average root number per cutting were increased by 58.9%. It had the best cuttage effect thatTrachelospermum jasminoidescuttings soaked with the solution of 200 mg·L-1 NAA and 200 mg·L-1 IBA, the increase rates of rooting rate and survival rate were 24.5% and 19.1% respectively, compared to the control, and the increase rates of average root number per cutting was 66.7%.
