This study reports finding of two rootstock experiments planted in 1997. The purpose of the first experiment was to evaluate the performance of Pinot noir on 19 phylloxera-resistant rootstocks and as an ungrafted vine. The purpose of the second experiment was to evaluate the performance of V. Vinifera cultivars Pinot...
Grafting, which involves combining two different varieties or species to form a plant with new characteristics, is a technique known from ancient times in tree fruit and grape production. It was, however, used in viticulture only for certain special cases: to change variety, increase vigor, or increase limestone tolerance.
A rootstock trial was established in 1997 at the OSU Woodhall vineyard, located in the Southern Willamette Valley, which included two experiments. The first experiment was a factorial of four varieties grafted on to 9 rootstocks, and also as ungrafted vines (a split-plot design). The second experiment was a randomized...
Winegrape growing is extremely dependent upon site-specific variables. To better understand the effect of rootstock-scion interaction in a cool climate region, an experimental vineyard was planted in 1997 at the Oregon State University Woodhall III property in the southern Willamette Valley. The first experiment consists of Pinot noir (clone FPMS...
The purpose of this study was to determine the relative tolerance of grafted
Vitis rootstocks to low soil pH. In this capacity, the data may be pooled with results
from previous investigations to increase the overall aptitude profile of Vitis
rootstocks. A potential application of this information is that the...

Sequence-specific PCR markers were derived from one new and eight previously identified random amplified polymorphic DNA (RAPD) markers for the purpose of identifying grape (Vitis) rootstocks. The markers were developed because the RAPD assay was found to be inconsistent and the original RAPD markers unreliable. Southern hybridization analysis of the...

The availability of new pear rootstocks could be increased by development of an efficient micropropagation system. Many P. calleryana, P. betulifolia and P. communis rootstocks are resistant to many pear diseases and are graft compatible with leading cultivars. Explains of three potentially useful rootstock selections P. calleryana Decne 'OPR 157',...
