The dye method for measuring leaf water potential is simple, inexpensive, and suitable for both laboratory and field work. Leaves are immersed in a graded series of solutions, and the solution which neither gains nor loses water is assumed to have a water potential equal to that of the leaf. Although limited by certain inherent errors, the dye method can be used to measure relative values and changes in potential. Specific procedures are described for the successful use of the method.
