Abstract
Abstract To investigate the effects of brown stem rot, a vascular disease of soybean ( Glycine max ) induced by Phialophora gregata , on the water relations of diseased plants, stems of greenhouse‐grown plants of susceptible (Pride B216) and resistant (BSR 201) cultivars were injected with the pathogen at vegetative growth stage VI. Plants of both cultivars developed internal stem browning, but those of Pride B216 developed more severe symptoms of water stress (reduced leaf water potential and stem conductance). Inoculated plants of both cultivars also had reduced stem conductance and increased stomatal conductance and transpiration. Disease‐related water stress can be attributed to the combined effects of reduced stem conductance and increased water loss resulting from increased stomatal conductance.
