Abstract
In root cells of a woody fruit species, Olea europaea L. cv. Frantoio, electrophysiological measurements were carried out for the first time. A strong dependence of electrogenesis on low temperatures emerged. The depolarization provoked by addition of K + was closely related to the external concentration of the ion. In addition, anoxia and DNP (2,4-dinitrophenol) reversibly depolarized the cell PD (electropotential difference). The plasma membrane was impaired by prolonged contact with the inhibitor.File | Dimensione | Formato | |
