pvldcurve (version 1.2.6)

Simplifies the Analysis of Pressure Volume and Leaf Drying Curves

Description

Simplifies the manufacturing, analysis and display of pressure volume and leaf drying curves. From the progression of the curves turgor loss point, osmotic potential, apoplastic fraction as well as minimum conductance and stomatal closure can be derived. Methods adapted from Bartlett, Scoffoni, Sack (2012) and Sack, Scoffoni, PrometheusWikiContributors (2011) .
