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

北美Vitus的种类在经济上很重要， 商品葡萄（Vitus vinifera L.）和作为 为生产新的杂交品种提供了种质资源。 对于本机 最有效地用于开发的葡萄品种 新种植的葡萄，它们的遗传多样性， 必须充分评估各种关系。 叶色素（类黄酮）的化学分析和解剖 特征将被用来推断物种之间的关系 产于北美洲东部的Vitus属的两个属。 结果 这种分析应该有助于确定最有可能的进化 物种的历史，并产生一个分类， 从农业和系统的角度来看是有用的。

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.
