摘　　要：侧金盏花(Adonis amurensis)是东北地区常见的一种早春类短命植物,也是一种观赏性状优秀的园林草本种质资源。本研究针对黑龙江省哈尔滨市帽儿山老山人工林试验站的野生侧金盏花,对其花部综合特征、开花动态、授粉特性进行了研究。结果表明,侧金盏花花期为3-4月,花型大,单花花期持续6~10 d,花部具有吸引传粉者的特征。侧金盏花雌蕊先熟,开花过程中花药与柱头无空间间隔,杂交指数结果为3,花粉胚珠比为2 280,结合套袋试验结果,判定侧金盏花繁育系统为兼性异交,自交可孕,需要传粉者进行传粉。Adonis amurensis is one kind of spring ephemeral perennial plant in northeast China and it is also one kind of excellent ornamental garden germplasm resource.A field investigation,including continuous observation,pollen/ovule rate( P/O) and fruit set rate,was conducted to study flower structure,flowering dynamic change and reproductive system of A.amurensis.The results showed that the population flower bloomed one time a year from March to April.The flower was large and the life span of individual flower were 6 ~ 10 days.Floral syndrome could attract pollinators.During the flowering phase,the pistil matured before stamens.At the same time,there were no space interval between stigma and anthers.The outcrossing index was 3 and the value of P/O was about 2 280.Combined these results with the results of bagging experiment,the reproductive system of A.amurensis could be determined as facultative outcrossing,self-compatible and pollinators depended.
