Digital morphometric analysis of North American Vitis growing in a common garden.

Phenotypic plasticity offers the opportunity for plants to adjust to changing environments. This dynamic observation has been made in many taxa across their geographic ranges. Common gardens allow researchers to examine effects of environment on phenotypes among various taxa and genotypes from across the species’ geographic range. Here, we use two, economically important North American grapevines (Vitis riparia and V. rupestris) to study leaf morphology in a common environment. By applying elliptical fourier descriptors (EFD) and generalized procrustes analysis (GPA) to digital images of leaves growing on vines in a common garden, we compare varation in shape, lobing, and sinus features among genotypes and between species. These results will be used in future work that integrates ion concentration and water use efficiency data for the common garden plot.
