Current Opinion in Plant Biology, 2002
Seed dormancy and germination are complex adaptive traits of higher plants that are influenced by a large number of genes and environmental factors. Studies of genetics and physiology have shown the important roles of the plant hormones abscisic acid and gibberellin in the regulation of dormancy and germination.

Molecular mechanisms of seed dormancy
Plant, Cell & Environment, 2012ABSTRACTSeed dormancy is an important component of plant fitness that causes a delay of germination until the arrival of a favourable growth season. Dormancy is a complex trait that is determined by genetic factors with a substantial environmental influence. Several of the tissues comprising a seed contribute to its final dormancy level.

Molecular Aspects of Seed Dormancy
Annual Review of Plant Biology, 2008Seed dormancy provides a mechanism for plants to delay germination until conditions are optimal for survival of the next generation. Dormancy release is regulated by a combination of environmental and endogenous signals with both synergistic and competing effects.

Dormancy Regulation in Peach Seeds
Science, 1966An inhibitor of seed germination was isolated from the integuments of Lovell peach seeds. Evidence from chromatographic analysis, from studies of its absorption of ultraviolet light and from assays on its effects on plant growth, indicate that the inhibitor is, if not identical with, dormin.

Chromatin Dynamics During Seed Dormancy
2011The chromatin structure determines gene expression and thereby regulates developmental processes in the plant. The molecular mechanisms regulating the induction and release of seed dormancy are still largely unknown and the underlying changes in chromatin organization have hardly been analyzed.

AbstractIris embryos were treated in several ways to study the cause of delayed germination. The results of this work indicate that a chemical inhibitor is present in the endosperm and mechanical inhibition of embryo growth also occurs. The mechanical inhibition reduces excised Iris embryo growth to the same extent as does the chemical inhibitor.

Standardizing Seed Dormancy Research
2011Seeds are very attractive and convenient for molecular genetic studies that challenge principal biological phenomena related to the initiation and suppression of growth (e.g., germination and dormancy, respectively). The number of reports in this field is rapidly expanding. Seed dormancy is a widely misinterpreted biological attribute.

Plant life begins with seed formation and is renewed when seed germinates. Seeds are highly dehydrated, quiescent or resting structures, and carriers of the next generation in the life cycle of plants. Seeds have different shapes and sizes, ranging from the smallest orchid seed (10−6 g) to the huge seed of the double coconut palm (30 kg).
