Digital Morphometrics of Two North American Grapevines (: Vitaceae) Quantifies Leaf Variation between Species, within Species, and among Individuals.

Recent studies have demonstrated that grapevine ( spp.) leaf shape can be quantified using digital approaches which indicate phylogenetic signal in leaf shape, discernible patterns of developmental context within single leaves, and signatures of local environmental conditions. Here, we extend this work by quantifying intra-individual, intraspecific, and interspecific variation in leaf morphology in accessions of North American and in a common environment.

Latent developmental and evolutionary shapes embedded within the grapevine leaf.

Across plants, leaves exhibit profound diversity in shape. As a single leaf expands, its shape is in constant flux. Plants may also produce leaves with different shapes at successive nodes.
