Competitive relationships amongst apomictic dandelions

The paper describes differences between six apomictic clones of dandelions as measured by dry weight increment when grown in competition with one another and when grown in competition with different grasses and as measured by leaf turnover, flowering and seed production of transplants in two different sites. The results suggest that mere is a genotype x environment interaction and that reproductive allocation in one site cannot be used as a predictive measure of reproductive allocation in a second site. The interactions between the dandelion clones and the grasses are interpreted in relation to the genetic uniformity within clones and are contrasted with similar interactions observed in sexual herbaceous species.
