万载龙牙百合开花生物学特性研究

Study on the Flowering Bioloial Characteristics of Lilium brownii var. viridulum in Wanzai County

[目的]探讨万载龙牙百合开花、传粉等生物学特性。[方法]以万载龙牙百合为试材,对其种球重量与开花数量、花期关系,以及开花动态、开花期间花粉生活力和传粉媒介等生物学特性进行了初步研究。[结果]种球重量在一定范围内与花朵数呈正相关;单花花期8~9 d,花粉在整个花期均具有活力;中片品系与柳片品系现蕾-开花时间差异显著;研究地的龙牙百合的访花昆虫主要是菜粉蝶、蜜蜂、蝇类和蚂蚁等,龙牙百合以虫媒传粉为主。[结论]该研究为龙牙百合杂交育种提供科学依据。

The research aimed to discussed the biology characteristics such as flowering and pollination other aspects of Lilium brownii var. viridulum. [Method]Taking Lilium brownii var. viridulum in Wanzai county as test materials,the biological characteristics of the relationships of its bulbs weight and the number of flowering,floweringperiod,flowering dynamics,as well as pollen viability during flowering and pollinators were studied.[Result]Bulb weight and flower number were related positively in a certain range;the single flowering period was 8- 9 days,the pollen vitality vigoroused throughout the flowering period. The lines and willow sheet strains bud- blossom time were significantly different.The flower-visiting insects of Lilium brownii var. viridulum mainly Pieris rapae,bees,flies and ants,Lilium brownii var. viridulum dominated by insect pollination.[Conclusion]The study provides a scientific basis for cross breeding of Lilium brownii var. viridulum.
