Conteúdo: 	Changes in components of leaf water potential during soil water deficits influence many physiological processes. Research results focusing on these changes during disiccation of peanut (Arachis hypogeae L.) leaves are apparently not available. The present study was conducted to examine the relationship of leaf water solute and turgor potentials, and percent relative water content (RWC) of peanut leaves during desiccation of detached leaves and also during naturally occurring soil moisture deficits in the field. The relationship of to and RWC was evaluated by calculating from differences in and determined by thermocouple psychrometry and by constructing pressure-volume (P-V) curves from the and RWC measurements. Turgor potential of Early Bunch and Florunner leaves decreased to zero at of-1.2 to - 1.3 MPa and RWC of 87%. There were no cultivar differences in the at which became zero.
