Heterochrony in Plants

Abstract

Heterochrony refers to a change in the relative timing or rate of development of morphological features that occur in the ancestor and the descendant. This is an evolutionary concept that invokes shifts in developmental timing as a major force in the evolution of new forms.

Keywords: phase change; juvenility; evolution; cleistogamy; flowering plants
