Abstract
Morphological variation, as expressed in PCA axis scores, for clovers growing in different aged pastures, was apportioned to pasture age, quadrats within pastures, intraspecific densities within quadrats, and genets within densities. Of those factors that have an effect on variation, genets is the greatest, followed by quadrats, intraspecific density, and age of the pasture. There is also an age-related decline in variation in plants of Trifolium repens as seen in genetic origin, quadrats within a pasture, and intraspecific density. These results indicate a need to determine more accurately the relationship between genetic and phenotypic responses in the decline in among-plant variation over time. Keywords: Trifolium repens, variation.
