Terminal velocity was greater in diploid seeds compared to triploid seeds. This difference was not significant if a nested design (ploidy, population, mother plant) was used but significant if the population level was not considered, indicating high interpopulation variation in this trait. Terminal velocity was positively and significantly correlated with seed mass, length and width and negatively correlated with pappus length and width. Germination probability was positively associated with seed mass and negatively with ploidy (higher in diploids, compared to triploids).
