Effects of Powdery Mildew of Grape on Carbon Assimilation Mechanisms of Potted ‘Chardonnay’ Grapevines

Potted grapevines (Vitis vinifera L. ‘Chardonnay’) were inoculated with conidial suspensions of the grapevine pathogen causing powdery mildew of grape (GPM) (Uncinula necator (Schw.) Burr.). Leaves of inoculated and noninoculated vines were studied for the effects of varying light (PAR) and CO2 concentrations on factors affecting carbon assimilation. GPM reduced carboxylation effi ciency (k), n...
