Seed dormancy is an adaptive mechanism that allows seed germination under suitable environmental conditions. Germination of stored dormant seeds proceeds after dormancy breaking induced by stratification. To improve understanding of dormancy breaking in beechnuts, we: investigated effects of moisture content and temperature during storage; analysed contents of abscisic acid, abscisic acid metabolites and indole-3-acetic acid in embryonic axes during storage and stratification; and histochemically localized storage proteins.

It is necessary to find convenient and measurable criteria for the evaluation of seeds/embryos quality before germination because of a long time interval between the preparation of seeds or embryos (before germination) and obtaining the seedlings or emblings. The success of all treatments before germination is assessed by the quality of the newly formed plants only.
