The Impact of <em>Phaeomoniella chlamydospora</em> Infection on the Grapevine's Physiological Response to Water Stress - Part 2 : Cabernet Sauvignon and Chardonnay
Phaeomoniella chlamydospora is a vascular pathogen that colonises the xylem tissues of the grapevine. It is associated with the diseases, esca and Petri disease, often considered to be ‘stress-related’ diseases. In glasshouse experiments using Cabernet Sauvignon and Chardonnay, stomatal conductance...

| description |
Phaeomoniella chlamydospora is a vascular pathogen that colonises the xylem tissues of the grapevine.
It is associated with the diseases, esca and Petri disease, often considered to be ‘stress-related’ diseases. In glasshouse
experiments using Cabernet Sauvignon and Chardonnay, stomatal conductance was higher in infected plants,
implying that infection interferes with stomatal control. In Cabernet Sauvignon, leaf water potentials were lower in
infected plants subjected to water stress, indicating that infection made it more difficult for the vine to get water to
the leaf. This was less apparent in Chardonnay. Clearly, infection alters the grapevine response to water stress and
some cultivars are affected more than others. |
