Comparison of Field Techniques for Measuring Moisture Stress in Large Loblolly Pines
In lobolly pine (Pinus taeda L.) oleoresin exudation pressure (OEP) was highly correlated with relative water content (RWC) of needles and water potential (WP) of twigs as measured by the pressure-chamber technique. Oleoresin exudation flow was correlated poorly with RWC and WP and not at all with OEP. The manometric technique of measuring OEP is a convenient and inexpensive way to estimate water stress in large loblolly pines. Forest Sci. 17:220-223.
