The tolerance of seeds to drying and its implication for germplasm conservation
Main Article Content
Abstract
This paper summarizes researches focused to study seed desiccation tolerance and ways to preserve them. The investigations it contains are related to the properties of the solid state of the cytoplasm of dried tolerant seeds. Also, the characteristics of desiccation sensitive seeds, and the general procedures for their long-term conservation are presented. Reference is made, considering different research papers, to the conceptual model that incorporates spatial and temporal effects of water loss to explain the cellular compression as damage origin, and the protection of dry matter reserves to the stability of solid cytoplasm and seed longevity.
