The critical transport velocity, dimensions (thickness, width, length), the angle of sliding friction and weight of Scots pine seeds from three batches were determined. Seed color was assessed in using an organoleptic test, and seeds were divided into three groups: gray, black and other. The measured parameters were used to calculate arithmetic and geometric mean diameter, aspect ratio, sphericity index, specific weight and density of seeds. Germination capacity was estimated every 12 hours, and germination rate was determined for each seed. The analyzed attributes were compared by the Student's t-test for independent samples, single classification analysis of variance and a correlation analysis. Germination capacity was somewhat improved by eliminating seeds with the lowest thickness from the examined material. The separation of seeds into color groups in an optical grader and individual processing of each group proved to be economically unfeasible. The above approaches did not lead to a significant improvement in germination capacity or germination uniformity. The percentage of non-germinated seeds was nearly twice higher in the "other" group than in the remaining color groups.
