Oregon State University researchers are expanding their study of mineral nutrition in winegrapes as part of a project sponsored by the Wine Advisory Board. Further research is justified because of increasing grower interest in nutritional factors that affect production and quality. Winegrape growers utilize Oregon State University's Plant Analysis Laboratory...
Objectives of Research :
1) Construct a whole-vine dry matter and mineral allocation budget for mature grapevines grown in Jory (basaltic parent material) soil.
2) Determine the associated seasonal dynamics of plant-available soil minerals.
3) Model the timing of uptake and allocation of mineral nutrients in different vine tissues.

Extensive information on rootstock resistance to lime is available since it has been one of the major selection criteria in Europe an rootstock breeding programs. Information regarding the performance of rootstocks in acidic soils however, is not so prevalent. Differences in genotype tolerance to high acidity maybe related to different...
