Viability constants based on eight years storage of beech nuts (Fagus sylvatica L.)

This research note is a follow up on results published in Poulsen (1993). I n 1993 viability constants based on approximately two years storage were ca lculated, in the present research note similar calculations are made after eight years storage. It was confirmed, that the viability equation applies to beech nuts stored at moisture contents up to 16%. The viability constant s for temperature do not differ significantly from those determined in stud ies of other orthodox species.
