Beechnuts from three Fagus sylvatica lots were dried at 20°C to 5–6% or 8–9% (fresh weight basis) moisture content and stored at –7°C or –22°C for 3.5 or 4.5 years in sealed polyethylene bags containing air and routinely used for the long-term storage of beechnuts or vacuumed (de-aerated) polyethylene bags with air removed before sealing. The germination and viability (tetrazolium test) of beechnuts were determined according to the Czech Technical Rules (1997) once a year during storage. The results were subjected to factorial ANOVA and the means were compared using the Scheffe test at P > 0.05. Compared to beechnuts dried to an 8–9% moisture content a significant decrease in both germination and viability occurred in beechnuts dried to a 5–6% moisture content regardless of how long the beechnuts were stored. However, the effects of the other treatments (type of storage bag, storage temperature) were not significant.Keywords:beechnut storage; germination; tetrazolium viability; moisture content; storage temperature; bag
