The shapes of wine and table grape leaves: An ampelometric study inspired by the methods of Pierre Galet

Plants, People, Planet, 2021
Societal Impact Statement Leaf shapes are critical to the identification of grapevine varieties. Historically, measures of grapevine leaves were used to enforce appellation law and leaf shape is used to this day to distinguish economically important ...

Discrimination of grapevine varieties cultivated in the Czech Republic by Artificial Neural Networks [PDF]

Advances in Horticultural Science, 2012
An artificial neural network approach, based on fractal leaf parameters, and classical ampelography were used to identify nine grapevine varieties cultivated at the St. Claire’s vineyard, Prague Botanic Garden.

A high‐resolution model of the grapevine leaf morphospace predicts synthetic leaves

Plants, People, Planet
Societal Impact Statement Grapevine leaves are emblematic of the strong visual associations people make with plants. Leaf shape is immediately recognizable at a glance, and therefore, this is used to distinguish grape varieties.

Increases in vein length compensate for leaf area lost to lobing in grapevine. [PDF]

Am J Bot, 2022
Abstract Premise Leaf lobing and leaf size vary considerably across and within species, including among grapevines (Vitis spp.), some of the best‐studied leaves. We examined the relationship between leaf lobing and leaf area across grapevine populations that varied in extent of leaf lobing.

Vitis International Variety Catalogue (VIVC): A cultivar database referenced by genetic profiles and morphology

BIO Web of Conferences, 2015
The establishment of the Vitis International Variety Catalogue (VIVC) dates back to 1984. The idea was to virtually assemble all accessions maintained in the worldwide existing collections to face genetic erosion.

Identifying the Phenotypic Resemblances of the Vine Breeds by Means of Cluster Analysis [PDF]

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2009
The use of the multi-variate statistical methods for the description and recognition of vine breeds is a new preoccupation in the field of ampelography. Besides other well known methods (genetic and/or enzyme pattern analysis) cluster analysis offer the ...
