Bud Dormancy as a Bet-Hedging Strategy
The American Naturalist, 1996The presence of dormant buds allows grazed plants to compensate for destroyed active meristems. In this article we present a theoretical analysis of the adaptive significance of bud dormancy when the risk of herbivory varies from year to year. Under constant herbivore pressure, selection tends to favor either plants that have no dormant buds and hence ...

Nearly all land plants produce ancillary meristems in the form of axillary or adventitious buds in addition to the shoot apical meristem. Outgrowth of these buds has a significant impact on plant architecture and the ability of plants to compete with neighboring plants, as well as to respond to and survive environmental hardships.

The Mechanism of Bud Dormancy in Plants
Advanced Materials Research, 2012The seasonal cycling between growth and dormancy has received little attention despite its importance for plant behaviour. Many factors are involved in dormancy regulation, which include environmental factors, such as phytohormones, photoperiod and temperature.

Dormancy in Seeds and Buds II.
Madras Agricultural Journal, 1968In an attempt to understand the physiological causes underlying dormancy, detailed investigations were carried out during the current century to correlate dormancy with biochemical changes occurring in the dormant organs. In recent years, the emphasis has passed over to a study of the role of endogenous growth regulators in controlling dormancy and a ...

In previous chapters, we discussed plant growth and development as a continuous process that proceeds without interruption from the germination of seed to the formation of the adult plant bearing flowers, fruits, and seeds. In most species, growth is not necessarily a continuous process as it may be suspended for varying periods of time in the life ...

Abscisic acid catabolism enhances dormancy release of grapevine buds
Plant, Cell & Environment, 2018AbstractThe molecular mechanism regulating dormancy release in grapevine buds is as yet unclear. It was formerly proposed that dormancy is maintained by abscisic acid (ABA)‐mediated repression of bud–meristem activity and that removal of this repression triggers dormancy release.

Modelling compensatory regrowth with bud dormancy and gradual activation of buds
Evolutionary Ecology, 2000Many plants show compensatory regrowth after herbivory and dormant buds often have an important role in compensatory responses. Theoretical models have shown that herbivore damage may select for a bud bank, i.e., a pool of dormant buds that are protected from herbivory and that are activated after herbivore damage. Earlier models assumed that undamaged

Dormancy and bud burst in Sultana vines
2017Dormancy and bud burst have been studied for sultana vines in the Murray Valley, Australia. The vines are in deep dormancy at the beginning of autumn and the intensity of dormancy decreases gradually during autumn and winter. Bud burst of cuttings taken during the dormant period occurs the more rapidly the higher the temperature at which they are held.

Chemical Breaking and Induction of Bud Dormancy
1974Temporary suspension of growth, or deceleration to barely perceptible rates, called dormancy, is a common feature of the ontogeny of seed plants. Dormancy is a phenomenon of profound biological significance, because it provides a means by which plants are enabled to survive periods of environmental conditions which would be adverse or lethal to plants ...

Studies on bud dormancy of woody species
1982The role of endogenous inhibitors and growth substances in the regulation of bud dormancy of wood plants was investigated using mature trees, seedlings, isolated shoots, and aseptically cultured buds and shoots. The photoperiodic induction of dormancy was not mediated through changes in inhibitor β activity, or ABA levels of buds and leaves of Alnus ...
