Beechnuts from three Fagus sylvatica lots were dried at 20 deg C to 5-6% or 8-9% (fresh weight basis) moisture content and stored at -7 deg C or -22 deg 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 polyethylene bags. The germination and viability (tetrazolium test) of beechnuts were determined according to the Czech Technical Rules (1997) once a year. The results were subjected to factorial ANOVA and the means were compared using the Scheffe test at P more than 0.05. Compared with 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.
