Abstract
The effects of different strains of grapevine leafroll disease (LR) on the composition of field-grown Sultana grapes were examined. A high-yielding Sultana clone without symptoms was graft-inoculated with bud material from itself or from low-yielding clones which habitually showed mild or severe LR symptoms. Vines with mild or severe LR symptoms had higher malate, tartrate, and potassium concentrations in berries than did vines without symptoms. Vines with severe symptoms had smaller berries with higher tartrate concentrations than did vines with mild symptoms, whereas concentrations of malate and potassium were similar. The magnitude of effects of LR strain on the acid characteristics of grapes is discussed in relation to variety, rootstock, and climate.
