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.

On dormancy strategies in tardigrades
Journal of Insect Physiology, 2011In this review we analyze the dormancy strategies of metazoans inhabiting "hostile to life" habitats, which have a strong impact on their ecology and in particular on the traits of their life history. Tardigrades are here considered a model animal, being aquatic organisms colonizing terrestrial habitats.

Scientia Horticulturae, 1981
Abstract Studies were conducted on 19 cultivars representing 4 species of Capsicum to determine the expression of dormancy in seed germination and emergence. Differences in dormancy were found among cultivars. Fruit age was shown to affect dormancy. Warm, dry storage shortened the length of dormancy while still maintaining a high level of emergence.

Annual Review of Entomology, 1986
Diapause is frequently viewed as a developmental strategy unique to insects of the temperate zone. My primary objective in this review is to dispell this myth by presenting evidence for the widespread existence of diapause among tropical species. Although the environmental regulators are still poorly defined, I attempt to identify factors implicated in

ject is given by Chesney.1 The prolonged quiescence or dormancy shown by a few cells in a transplant, while of considerable more importance to the experimental bacteriologist than the lag, has escaped serious investigation until recently. Burke 2 described the prolonged dormancy of a small percentage of the spores of CI.

Publisher Summary This chapter discusses dormancy, which is an inactive state associated with metabolic depression and arrested development that promotes the survival of insects during periods of harsh environmental conditions, including high or low temperatures or moisture conditions and reduced food quality or availability.

Dormancy: Manifestations and Causes
2001During their life cycles, plants are exposed to periods of stress caused by low or high temperatures, drought, or other environmental factors. In the course of evolution, complex defense mechanisms have developed for protection against such stresses. One such mechanism is dormancy.

The localization of the Kip-related proteins to meristematic regions suggests that these proteins might be associated with dormancy regulation. Additionally, the localization of chromatin remodeling to specific genes and loci may reveal the important regulation mechanisms for the dormant state.

Dormancy and the Control of Germination
1985Whether or not a viable seed germinates and the time at which it does so depend on a number of factors, including those present in the seed’s environment. First, the chemical environment must be right. Water must be available, oxygen may have to be present since the seed must respire, and noxious or inhibitory chemicals should be absent.

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 ...
