To understand the adaptation of grape rootstocks commonly used in major grape production areas worldwide to Florida, where Pierce’s dsease (PD) is the primary limiting factor in grape production, ten important grape rootstocks were cultivated at the experimental vineyard, Florida A&M University, Tallahassee, Florida. Disease resistance and symptoms and growing performance were evaluated. PD sym...

Background and Aims The use of rootstocks to enhance the performance low-yielding wine cultivars grown under hot irrigated conditions was studied. Methods Results Field grape composition low-vigour (Chasselas, Egiodola, Ehrenfelser, Gamay, Perdea, Reichensteiner Roussanne) as own roots or grafted on (1103 Paulsen, Dog Ridge, Ramsey, Schwarzmann SO4) were assessed over three seasons. Across all ...
