Cananga odorata(Lam.)Hook.f.是一种热带树种，用于生产伊兰精油，从其新鲜和成熟的花朵中提取。尽管它在经济和社会上具有重要意义，但关于它的可变性和引起它的可能因素的信息很少。因此，研究了印度洋三个岛屿(大科莫尔岛、马约特岛和马达加斯加岛)半管理系统种植的依兰的遗传结构(AFLP)和精油化学成分(GC/MS)之间的关系。我们的结果显示，种植园内的遗传变异较低，岛屿之间的情况也存在差异。在种植园内和岛屿之间可以观察到化学成分的变化。遗传分化模式与观察到的化学变异性模式不匹配。因此，这种化学变化不能归因于基因控制。由于大科莫尔、马达加斯加和马约特呈现不同的环境和农艺条件，因此可以得出结论，这些条件对依兰精油组成的影响与观察到的模式是一致的。最后，提出了几种评估化学成分变化的策略。
Cananga odorata (Lam.) Hook.f. & Thomson forma genuina (Annonaceae) is a tropical tree, grown for the production of ylang-ylang essential oil, which is extracted from its fresh and mature flowers. Despite its economic and social importance, very little information is available on its variability and the possible factors causing it. Therefore, the relationship between the genetic structure, revealed by amplified fragment length polymorphism (AFLP), and the essential oil chemical composition, determined by GC/MS analysis, of ylang-ylang grown in semi-managed systems in three Indian Ocean islands (Grande Comore, Mayotte, and Madagascar) was investigated. Our results revealed a low genetic variation within plantations and contrasted situations between islands. Variations of the chemical composition could be observed within plantations and between islands. The genetic differentiation pattern did not match the observed pattern of chemical variability. Hence, the chemical variation could not be attributed to a genetic control. As Grande Comore, Madagascar, and Mayotte present different environmental and agronomic conditions, it can be concluded that the influence of these conditions on the ylang-ylang essential oil composition is consistent with the patterns observed. Finally, several strategies were proposed to valorize the chemical composition variations.
