Abstract
Schulte, P. J. and Hinckley, T. M. 1985. A comparison of pressure-volume curve data analysis techniques.—J. exp. Bot. 36: 1590–1602. Computer assisted analysis of data derived with the pressure-volume technique is currently feasible. In this study, various computer algorithms were used to analyse a variety of pressure-volume curve data sets. Comparisons were made with respect to estimates of osmotic potential, turgor loss point, symplastic fraction, and bulk modulus of elasticity. While osmotic potential estimation was fairly insensitive to the model used, estimates of the bulk modulus of elasticity appear to be highly dependent on the model used for analysis of the data.
