Improving Tree Seed Germination by Electrostatic Field

Tree species with shallow dormancy are used for reforestation by airplane sowing in order to establish forest in mountain areas. To enhance germination, the quality of young seedling, an electrostatic field is used to treat pine seeds. Experiments found that treatment effect depended on the dosage, process and vigor index of seeds, and the optimal dosage was 500 kV/m 10 minutes for dry or wet seeds to improve germination, seedling height and root length during initial germination and middle and later stages of seedling development.
