4种球根盆花的生育特性·植物学性状及花期调控研究

Study on Growth and Development Characteristics,Botanical Characteristics and Flowering Period Control of Four Flower Bulbs

[目的]对4种球根花卉郁金香、风信子、洋水仙及朱顶红的生育特性、园艺学性状及花期调控进行研究。[方法]以不同方法栽培郁金香、风信子、洋水仙及朱顶红球根,观察生育特征;通过冷藏、去皮及赤霉素处理,调控花期。[结果]4种球根花卉品种的生育期差异较大,但在昆明地区种植均表现优良,成花率达98%以上。用2℃低温冷藏盆花,可有效地延迟郁金香、风信子、洋水仙的花期;赤霉素处理和去皮处理,可提早郁金香的花期。[结论]该研究可为郁金香、风信子、洋水仙及朱顶红的大规模推广应用提供理论依据。

[ Objective ] The research aimed to study the growth and development characteristics, botanical characteristics and flowering period control of four flower bulbs of Tulipa gesneriana,Hyacinthus orientalis,Narcissus pseudonarcissus and Hippeastrum vittatum. [ Method ] The four flowerbulbs were all cultured with different methods, and their characteristics of growth and development were observed at the same time. Their flowering periods were regulated with GA or peeling treatment. [ Result ] The results showed that the periods of growth and development were quite different among these four flower bulbs, but they all grew very well in Kunming area, all with the rate of flowering over 98%. The flower- ing periods of potted T. gesneriana, H. orientalis, N. pseudonarcissus were effectively delayed when storaged at 2 ℃ , while the flowering period of T. gesneriana could be advanced with the treatment of GA or peeling. [ Conclusion ] This research could provide important theoretical references for the wide applications of T. gesneriana,H, orientalis, N. pseudonarcissus and H. vittatum.
