光照强度对百合开花质量和花期的影响

摘要

为了解光照强度对百合从出芽到花朵衰败期间生长发育的影响,试验以全光照和遮阴2种方式盆栽百合.结果表明,全光照条件下,小重瓣提前1d开花,群体花期缩短1d,花蕾长、花瓣长和花朵直径均显著高于遮阴条件下的;其他百合在全光照条件下花期不同程度推迟,开花时间缩短2～5d,其中,小珍珠、冲绳县和八点后的开花质量显著低于遮阴条件下的;博内尔岛和演员在2种光照强度下的开花质量没有显著差异.可见,不同品种的百合对光照强度的需求不一,栽培时应区别对待.%To understand the effect of light intensity on lily growth and development from budding to flower down falling,six potted lilies cultivars were planted under full sunlight and shade conditions.The result showed that Tiny Double You bloomed a day earlier and lasted one day shorter under full sunlight.Flower quality,namely the length of flower buds and petal,and flower diameter,of Tiny Double You planted under sunlight were significantly larger than those planted under shade.In contrast,blooming times were postponed and flowering period was shortened for 2-5 days for other five lilies when planted under full sunlight.The flower qualities of Tiny Pearl,Sunny Okinawa and After Eight planted under full sunlight were significantly inferior to those planted under shade,while there were no significant differences in flower qualities of Sunny Bonaire and Entertainer under two light intensity conditions.All in all,different lily cultivars should be planted under different light conditions,since they depend on different light intensity for better growth.
