Electrophysiological techniques, pioneered and developed by workers in the biomedical sciences, can be useful in forest tree research. In the examples presented, electrical potentials of Pinus elliottii var. elliottii Engelm. were closely associated with the presence or absence of female flower buds prior to their emergence, with differences in electrical polarity between excised pollinated and unpollinated slash pine ovules, and with the magnitude of the potential difference between the nucellar surface and points on the dorsal surface of the ovule. Electrical potentials are also shown to be significantly related to the geographic distribution of slash pine.
