The effects of Pierce's disease on leaf and petiole hydraulic conductance in Vitis vinifera cv.Chardonnay

Choat, Brendan; Gambetta, Greg A; Wada, Hiroshi; Shackel, Kenneth A; Matthews, Mark


In this study, we test the hypothesis that the symptoms of Pierce's Disease (PD) result from the occlusion of xylem conduits by the bacteria Xylella fastidiosa (Xf). Four treatments were imposed on greenhouse-grown Vitis vinifera cv. Chardonnay: well-watered and deficit-irrigated plants with and without petiole inoculation with Xf. The hydraulic conductance of the stem-petiole junction (kjun) and leaves (kleaf) were measured, and Xf concentrations were established by quantitative polymerase...[Show more]
