Quantitative Trait Loci Influencing Elemental Content In Grapevine Leaves, Jesse L. Krokower
MSU Graduate Theses
In grapevine, the influence of the plant’s elemental composition (the ionome) on fruit and wine quality is well established, but its genetic underpinnings have received limited scientific attention. In this study, I analyzed the leaf ionome of 131 interspecific F1 hybrid progeny plants from a cross between a Vitis rupestris Scheele (♀) and a Vitis riparia Michx (♂) parents, which were replicated in four different environments: Southwest Missouri, Central Missouri, South Dakota, and New York. I sampled leaves at three different times during the growing season at all four locations and had the concentration of 20 elements measured using ICP-MS. …
