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.

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).

Seed dormancy: General survey of dormancy types in seeds, and dormancy imposed by external agents
1965Two basic kinds of dormancy have been distinguished by Bunning (1947): ectogenous, influenced by external factors such as light, temperature, water, etc.; and endogenous, conditioned by the internal constitution of the seed. Whether seeds possess either one or both of these types of rest depends upon two main factors, environmental influences and ...

The seeds of some plant species are dormant and will not germinate when they are placed in an environment generally conducive to germination, that is to say, in conditions of appropriate warmth, moisture and aeration. In some of these, the embryo must undergo physiological and in some cases morphological changes before germination occurs. These changes

Grasses are a principal source of food for mankind and play an important role in stabilizing the land surface of much of the globe. Understanding seed dormancy in the Gramineae is therefore of considerable significance to world agriculture and global ecology.
