The lifespan or longevity of a seed is the time period over which it can remain viable. Seed
longevity is a complex trait and varies greatly between species and even seed lots of the …

Background Considered only in terms of tolerance of, or sensitivity to, desiccation (which is
an oversimplification), orthodox seeds are those which tolerate dehydration and are storable …

During germination, the most resistant stage of the life cycle-the seed-changes to the most
sensitive stage, namely the seedling. Therefore, in desert plant species seed dispersal and …

Mature desiccation-tolerant (orthodox) seeds will retain viability for varying periods
depending upon the species and the storage conditions. A number of distinct but interacting …

A suite of mechanisms or processes that together have been implicated in the acquisition
and maintenance of desiccation tolerance in orthodox seeds is discussed in the context of …

Preface viii development of vitrification techniques provided a second approach that is
applicable even to tropical plants. Several techniques were developed, but the development …

This chapter reviews the possible mechanisms of desiccation tolerance in seeds. It
discusses some of the anatomical, biochemical, and biophysical events associated with the …

The two basic approaches to conservation of plant genetic resources are ex situ and in situ
conservation. Article 2 of the Convention on Biological Diversity (UNCED 1992) provides the …

The regeneration of plant communities from seed depends on seeds being in the right
physiological state to germinate in the right place at the right time. In some species, this …
