密度和品种对满天星异速生长的影响。研究了增加密度显著降低了"新面孔"的鲜重、总分支长度（所有一级分枝的长度之和）、二歧花序数、每二歧花序的小花数和切花的小花总数。鲜重与总分支长、二歧花数和小花总数分别呈负异速生长、等长和正异速生长关系。鲜重与二歧花序数、每二歧花序小花数、各分支级小花总数之间存在异速生长关系。异速生长指数的回归有关的二歧花的数量和总小花数鲜重增加从低到高阶分支。另一方面，异速生长指数的回归关系的小花数每二歧聚伞花序鲜重是相似的，几乎在所有的订单。在相同密度下，不同品种间的花序结构参数和鲜重存在显著差异。异速生长指数有关的总分支长度和数量的二歧花鲜重，变化，和那些有关的小花总数鲜重是稳定的品种在相同的植物密度下生长。
The effect of plant density and variety on allometry in Gypsophila paniculata L. was studied. Increasing plant density significantly reduced fresh weight, total branch length (the sum of the lengths of all primary branches), number of dichasia, number of florets per dichasium, and total number of florets in cut flowers in ‘New Face’. The relationships between fresh weight and the total branch length, number of dichasia, and total number of florets were negatively allometric, isometric, and positively allometric, respectively. There were allometric relationships between fresh weight and the number of dichasia, number of florets per dichasium, and total number of florets on each branch order. The allometric exponents of regression relating the number of dichasia and the total number of florets to fresh weight increased from lower- to higher-order branches. On the other hand, the allometric exponents of regression relating the number of florets per dichasium to fresh weight were similar in almost all orders. Significant differences were found in fresh weight and parameters of inflorescence architecture among varieties grown under identical plant density. Allometric exponents relating the total branch length and number of dichasia to fresh weight, varied, and those relating the total number of florets to fresh weight were stable among varieties grown under identical plant density.
