This chapter considers aspects of the maternal parent, other than the tissues immediately around the seed, which contribute to the distances dispersed by plant propagules. It shows how plant phenotype, the abiotic environment, competition, and herbivory all help to determine where the trajectories of propagules begin. Plant phenology dictates when the force required separating the propagule from its parent is at a minimum, and therefore when the trajectory is likely to begin. This can be critical for the survival of animal vectors as well as for movement of seeds contained in fruits. In some cases, the parent provides an additional force to launch the propagule away from its parent.
