摘要：Tree seed germination improvement of tree species with shallow dormancy may represent an effective process to enhance restocking of forests and woodlands that have been depleted. Although sometimes conflicting results have been obtained, some studies showed the beneficial effects of applied static electric field (electrostatic field) on seed germination and seedling growth. We think that the different treatment effects reported maybe depended on the dosage, exposition time, process and vigor index of the seeds. We previously showed improved tree seed germination of pine seeds by positive electrostatic field treatment using our apparatus and procedure, and the purpose of the present study was to investigate the effects of the negative electrostatic field treatment on germination, using the same experimental procedure. The results indicated that the negative electrostatic field treatment on pine seeds soaked with 100 ppm of gibberellic acid (GA3) is not so effective as the positive one, with slightly improved germination percentage at the electrical voltage of -500 kV/m 10 min, and increasing the intensity of the negative electrostatic gradient resulted in a reduction of seedling growth.
