Dissertation Research: A Systematic Study of Eastern North American Vitis (Vitaceae) North of Mexico

北美葡萄属植物作为商品葡萄(Vitus vinifera L.)砧木具有重要的经济价值。为杂交新品种的选育提供种源。为了最有效地利用本地葡萄品种开发新的栽培葡萄，必须充分评估它们的遗传多样性和亲缘关系。叶色素(类黄酮类)的化学分析和解剖特征将被用来推断北美东部两个属的藤本植物之间的关系。这一分析的结果应该有助于确定该物种最有可能的进化史，并产生一个从农业和系统角度被证明有用的分类。

The species of North American Vitus are economically important as rootstocks for the commercial grape (Vitus vinifera L.) and as a germ source for production of new hybrid cultivars. For native species of grapes to be most effectively used in the development of new cultivated grapes, their genetic diversity and relationships must be adequately assessed. Chemical analyses of leaf pigments (flavonoids) and anatomical characteristics will be used to infer relationships among species in two genera of Vitus from eastern North America. Results from this analysis should help determine the most likely evolutionary history of the species and produce a classification that will prove useful from an agricultural and systematic standpoint.
