相关性pleiades现象，即生物体某些部分的某些数量特征之间存在相关性，同时这些部分与其他部分之间不存在相关性，表明生物体内某些发育过程相对于其他过程是独立的，因此是发育稳态的表现。19种草本植物已被研究，以确定在一个有机体的营养（茎，叶，花序）和生殖（花被和花）部分的尺寸之间的依赖程度的变化。已经确定，在12个物种中，花被和花的尺寸被组织成相关的pleiad，而7个物种相对于类似部分的尺寸没有相关的pleiad。相关昴宿星的存在与特定昆虫传粉者的存在有关。昆虫是稳定花的那些部分的尺寸的选择因子，这些部分参与花粉在昆虫身体上的精确定位过程。涉及花维度的相关昴宿星是它们选择作用的结果。定量标准的采用为稳定选择研究中的比较方法提供了充分的依据。
The phenomenon of correlation pleiades, i.e. the presence of correlations between some quantitative characteristics of certain parts of an organism and at the same time the absence of correlations between these and the other parts demonstrates the independence of certain developmental processes with respect to other processes within the organism and is thus the manifestation of developmental homeostasis. Nineteen species of herbaceous plants have been studied in order to determine the variability in the degree of dependence between the dimensions of vegetative (stems, leafs, inflorescences) and reproductive (perianths and flowers) parts of an organism. It has been established that in 12 species the dimensions of perianths and flowers are organized into a correlation pleiad while 7 species have no correlation pleiades with respect to the dimensions of analogous parts. Existence of correlation pleiades is associated with the presence of specific insect pollinators. Insects were the selective factor stabilizing the dimensions of those parts of flowers which participate in the process of the precise localization of pollen on the insect body. Correlation pleiades involving flower dimensions are the result of their selective action. The adoption of a quantitative criterion provides an adequate basis for the comparative method in the study of stabilizing selection.
