Abstract: In this study, the effects of winter-spring greenhouse cultivation on the florescence, crown width, plant height, bud weight, branches number, bud number and contents of four main aroma components of jasmine (Jasminum sambac). The results showed that compared with the field cultivation, the florescence of jasmine opened about 10 days earlier and had longer than 35 days, bloom phage under greenhouse cultivation. However, the crown width, the number of branches and the number of flower buds per plant increased faster in July and August, and significantly higher in August, September and October. There was no significant difference in plant height, bud weight and bud diameter between greenhouse cultivation and field cultivation. Compared with the field cultivation, the aroma substances in jasmine flower buds did not change under the greenhouse cultivation, the contents of total and main aroma components, linalool, farnesol, and benzyl acetate were not significantly different in June, August and October. These results could provide a reference for the future study on extending florescence, changing quality and increasing economic benefit through protected cultivation of Jasmine.

摘要： 分析冬春大棚栽培茉莉Jasminum sambac花期、冠幅、株高、蕾重、分枝、花蕾数以及4种主要香气物质含量的变化。结果显示，冬春大棚栽培茉莉相比露地栽培花期提早10 d左右，花期延长35 d左右；冬春大棚栽培下茉莉冠幅、分枝数、单株花蕾数在7、8月增长更快，在8、9、10月显著高于露地栽培，但株高、百蕾重、蕾径在各月与露地栽培同期相比无显著差异；与露地栽培相比，冬春大棚栽培下茉莉花蕾中香气物质种类未发生变化，总香气物质和主要香气物质芳樟醇、法呢烯、乙酸苄酯含量在6、8、10月无显著差异。该研究可为通过茉莉花设施栽培延长花期、改善品质、提高经济效益的研究提供参考。
