依兰香(Cananga odorata)为热带木本香料植物,树姿优美,花期长,花香浓郁,原产于菲律宾和印度尼西亚爪哇岛。本研究从印度尼西亚和缅甸引进4个依兰香种源,在我国南亚热带地区进行引种栽培试验。结果发现:1.5 a生依兰香苗期种源间生长差异显著,其中,5M种源生长较快,其树高达0.55 m,地径0.61 cm,造林成活率达到95%以上;3.5 a生种源试验林平均树高可达4.32 m以上,地径10.44 cm以上,胸径6.38 cm以上,且生长发育正常,无病虫害,抗寒能力较强;种源1K和3L较早进入始花期;从适应性和早期生长表现来看,种源2P和5M优于种源1K和3L。这些研究为我国香料植物新品种的引进与开发利用,以及在城市林业中的发展提供理论和实践依据。
Ylang-ylang (Cananga odorata) is a tropical woody spice plant, beautiful tree posture, long flowering period, floral rich, native to the Philippines and Indonesia, Java Island. In this study, four Ylang-Ylang sage sources were introduced from Indonesia and Myanmar, and introduced and cultivated in the subtropical region of China. The results showed that there was significant difference in the growth of 1.5-year-old Ylang-lan seedlings, among which, the 5-year-old provenances grew faster, the tree height was 0.55 m, the diameter was 0.61 cm, and the afforestation survival rate reached above 95% The mean tree height of experimental forest was more than 4.32 m, the diameter was 10.44 cm, the diameter at breast height was 6.38 cm, the growth rate was normal, no pests and diseases were found, and the ability of cold resistance was stronger. And early growth performance point of view, provenances 2P and 5M better than the provenance 1K and 3L. These studies provide theoretical and practical basis for the introduction, development and utilization of new varieties of spice plants in our country and the development in urban forestry.
