摘要
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）, a woody fragrant plant in tropical regions, is characterized by beautiful tree appearance, long flowering period, strong fragrance and oil distillation of flowers, and originally distributed in the Philippines and Indones＇s Java islands. In this study, four provenances of ylang-ylang from Indonesia and Myanmar were introduced and cultivated in the subtropical region of southern China. Results showed that, the difference of some growth indexes such as height and basal diameter between 1.5-year-old seedling provenances was significant, and provenance 5M was superior with height 0.55 m, and basal diameter 0. 61 cm ; In forestation, ylang-ylang had a high survival rate 〉95%. The height, basal diameter and diameter at breast height of 3.5-year- old plantation was 〉 4.32 m, 〉 10.44 cm, 〉 6.38cm, respectively, which displayed normal growth and development, and strong resistance against disease, low temperature; Flowering was earlier in two provenances （1 K and 3L）; According to the ecological adaptability and early representation on growth, two provenances （2P and 5M） excelled than the other. These results laid a solid foundation for the introduction and application of fragrant plants and for the development of urban forestry in China.
