The basic dimensions and the mass of common beech nuts and seeds from five nut batches, harvested from tree stands in northern Poland, were determined. Environmental conditions had a greater influence on seed plumpness than the age of tree stands. The results of measurements were analyzed statistically by analysis of variance, correlation analysis and linear regression analysis. Despite differences in their plumpness, nuts were characterized by nearly identical cross-sections which resembled an equilateral triangle. The thickness of nuts and seeds was highly correlated with their mass, and this information can facilitate seed husking and separation into mass categories. Before and after husking, seeds should be separated with the use of a mesh screen with longitudinal openings. Medium-sized (most numerous) seeds were separated into the following plumpness categories using a screen separator with ≠6 mm and ≠7 mm openings: 84% of moderately plump seeds, 3% of seeds with reduced plumpness, and 13% of plump seeds.

Abstract. Die Neuuntersuchung des Interglazialvorkommens von Fahrenkrug bei Segeberg (Holstein) ergab ein saale/weichselinterglaziales Alter (Zone e bis i). Die Angabe von Rotbuche, Fagus silvatica L., muß auf eine Fehlbestimmung zurückgeführt werden. Da bisher Rotbuchenfunde älteren Datums durch Nachuntersuchungen nicht bestätigt werden konnten, muß mit dem Fehlen von Fagus mindestens für das Jungpleistozän Nord- und Mitteleuropas gerechnet werden. Ausnahmen, die vermutlich in ein Würm-Interstadial zu stellen sind, sind aus dem Alpengebiet bekannt. Möglicherweise hängen hiermit fernverwehte Buchenpollen in einigen Fundplätzen des Brørup-Interstadials zusammen.
