Resumen:
Germination represents the culmination of the seed developmental program
and is affected by the conditions prevailing during seed maturation in
the mother plant. During maturation, the dormancy condition and
tolerance to dehydration are established. These characteristics are
modulated by the environment to which they are subjected, having an
important impact on wild species. In this work, a review was made of the
molecular bases of the maturation, the processes of dormancy imposition
and loss, as well as the germination process in different wild species
with different life histories, and from diverse habitats. It is also
specified which of these species present a certain type of management.
The impact that the domestication process has had on certain
characteristics of the seed is discussed, as well as the importance of
determining physiological stages based on morphological characteristics,
to face the complexities of the study of these species and preserve
their genetic diversity and physiological responses.
