依兰香一般用种子繁殖。由于其种皮厚,表皮背面有一层蜡质,不易渗水,播后很难吸胀开裂,需较长时间胚根才能伸出,所以出芽慢,不整齐。目前国外有关这方面的资料较少。据马尔加什报导,用70°—80℃温水浸种,冷却后即行播种,能促进种子萌发。我们引用此法进行了试验,结果不太满意。云南西双版纳依兰香种子成熟期正处冬季低温阶段,种子发芽更慢。如何搞好播种育苗工作,是急待研究解决的问题。从1973——1978年以来,我们对依兰香种子处理和冬季育苗进行了反复试验,现将我们的初步认识概述于后:
Ylang ylang general breeding with seeds. Because of its thick seed coat, the back of the epidermis has a layer of wax, not easy to seepage, it is difficult to swollen after sowing cracking, take a long time radicle can extend, so budding is slow, irregular. At present, there is less information on this subject in foreign countries. According to Malagasy reports, with 70 ° -80 ℃ warm water soaking, sowing after cooling, can promote seed germination. We cite this method was tested, the results are not satisfied. Yunnan Xishuangbanna ylang ylang seed mature stage is in winter low temperature stage, the seeds germinate more slowly. How to do a good job sowing seedling work is an urgent need to study and solve the problem. From 1973 to 1978, we tested the ylang-ylang seed treatment and winter nursery repeatedly, and we outline our initial understanding later:
