研究了满天星的花序组成。对‘布里斯托尔仙女’进行了6个生育期的评估，以确定花序发育的规律性和可塑性。花序(花枝)在这里被认为是许多花序单位(二叉花序)的集合体，因为它的形式具有层次性。为了确定花序组成的季节变化，采集了整个花序及其单位的数据。花序发育非常规律。在单个花序中，茎的横截面积与小花数之间存在着一定的相关性。在一个单位内，最高可见小花数、小花数和鲜重与花序单位轴直径呈正相关。花序组成随播种期的不同而变化。从春季到夏季，花序至开花天数、花序鲜重、茎长、节数、一次、二次分枝数和小花数呈减少趋势，而单位鲜重、花序单位轴直径、可见小花最高级数和小花数呈增加趋势。
The inflorescence composition of Gypsophila paniculata L. 'Bristol Fairy' was evaluated over six growing periods to identify both regularity and plasticity in inflorescence development. An inflorescence (a flowering shoot) was regarded here as an aggregation of many inflores-cence units (dichasia) because of the hierarchical nature of its form. To identify seasonal changes in inflorescence composition, data was taken of whole inflorescences and their units.Inflorescence development was very regular. In individual inflorescence, there was corre-lation between the cross-sectional area of the stem and the number of florets. In an unit, the highest order of visible florets, the number of florets, and the fresh weight were correlated with the diameter of the inflorescence unit axis.G. paniculata L. had considerable plasticity in inflorescence development. The inflorescence composition changed with the date of planting. From spring to summer, the days to flowering, fresh weight of the inflorescence, stem length, number of nodes, number of primary and secondary branches, and number of florets tended to decrease, but in units, the fresh weight, diameter of the inflorescence unit axis, highest order of visible florets, and number of florets tended to increase.
