Abstract: The focus of this research was to determine how vegetative and reproductive growth are partitioned under different density conditions in the plant Impatiens pallida. This was accomplished by regular censuses of reproductive organs and estimates of the size characters plant height, number of leaves, above ground biomass, length of longest branch, number of primary branches and diameter of the main stem. It was found that plants in a lower density treatment performed more vegetative growth than plants in naturally high density treatment. However, there were no significant differences in reproductive growth throughout the experiment. Further results showing that high density plants produced more flowers per branch while low density plants produced more flowers explains this paradox. These results indicate a differential partitioning of meristems to reproductive growth as opposed to vegetative growth in high density plants. It was also found that low density plants had significantly more leaves, primary branches and a significantly greater stem diameter to height ratio. Low density plants were also found to have significantly lower survivorship than high density plants.
