Abstract

In view of the finding that dry seeds may exist in the glassy state, a brief review of the commonest methods of detection and quantification of the glass transition is presented. While the glassy state may contribute to seed tolerance of desiccation, it does not appear to account for desiccation tolerance. Its major function in dry seeds may be its contribution to the stability of the seed components during storage.
