Phenotypic plasticity to nutrient availability in a wetland invasive species

Are triploid Butomus umbellatus plants more plastic to nutrient availability than diploid plants and does this make them more invasive?

Plants can become less uniform by duplicating their genome

Though the experiment was limited to two genotypes of a single species, these findings support the idea that whole genome duplication can indeed increase plasticity.
