    Powdery mildew (Erysiphe necator) (PM) is the most important and impacting fungal disease of grapevine (Vitis vinifera L). This disease remains difficult to model and forecast accurately because (i) the first signs of the disease in the vineyard are hardly noticeable in the first 30- 40 days after the onset of the epidemic (three to four pathogen ...
  • GRAPE RIPENING: WHY BERRY TRANSPIRATION AND XYLEM BACKFLOW MATTER MADURACIÓN DE LA UVA: POR QUÉ LA TRANSPIRACIÓN DE LA BAYA Y EL REFLUJO DEL XILEMA IMPORTAN
    ZHANG, Yun; KELLER, Markus* Washington State University, Irrigated Agriculture Research and Extension Center, 24106 N. Bunn Road, Prosser, WA 99350, USA *Corresponding author: mkeller@wsu.edu

    At the beginning of ripening, grape berries switch their water import pathway from the xylem to the phloem. However, the cause of the decline in xylem inflow remains a matter of debate. Applying xylemmobile dye in conjunction with root or shoot pressurization demonstrated that the direction of xylem flow was reversible and responded to pressure ma...

    Climate change scenarios predict increases in the frequency and severity of droughts in arid zones. Under these conditions some plants can rapidly acclimate to stress and further fortify their defenses by retaining memories of stress which enable stronger or more rapid responses if an environmental perturbation recurs. Yet, there are relatively fe...

    Grapevines are useful model plants for research on the physiology of water stress responses. Variable responses at the stomatal level have been described in different varieties with implications on the hydraulic conductance of the plant and eventually impacts on the tension imposed to the xylem architecture, depending on xylem properties. In order...
