Cell cycle inHelianthus tuberosus tuber tissue in relation to dormancy [PDF]
Protoplasma, 1982 Observations are presented on the patterns of DNA synthesis and mitotic activity in medullary parenchyma cells excised from tubers ofHelianthus tuberosus in four different periods of dormancy. Dormancy break (activation) was induced byin vitro culture on media added with 2,4-dichlorophenoxyacetic acid.

The Annual Dormancy Cycle in Buried Weed Seeds: A Continuum
BioScience, 1985The classic studies of Brenchley and Warington (1930) and numerous other investigations have demonstrated that large reserves (pools) of weed seeds accumulate in arable soils. Work reviewed by Kropad (1966) and Roberts (1981) shows that the number of seeds per m2 in the upper 15-25 cm of soil in cultivated fields may be as high as 70,000-90,000, and up

Plant and Soil, 2021
Seed dormancy and the formation of a soil seed bank is important plant regeneration strategies, especially if the environment is unpredictable. The present research explores how environmental factors control seed dormancy release, and how seed dormancy is related to the soil seed bank and regeneration of the perennial Aquilegia oxysepala.

Primary dormancy and annual dormancy cycles in seeds of six temperate wetland sedges
Aquatic Botany, 1997Abstract The effects of dry after-ripening and burial in the soil on seed germination of six temperate wetland Carex spp. were investigated. Freshly matured seeds, seeds stored dry for 4 or 8 weeks, and seeds buried at 7-cm depth in a small woodlot, and exhumed at approximately bimonthly intervals over a 2-year period, were tested under a ...

Regulation of Seed Dormancy Cycling in Seasonal Field Environments
2015Seeds respond to a range of environmental signals, using them for both temporal and spatial sensing to alter their depth of dormancy to ensure germination takes place in a favorable habitat and climate space, and in the correct season. Many signals have the potential to inform the seed about its environment; we consider the effects of temperature as a ...

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.

Seed Science Research, 2008
AbstractTorilis japonica (Apiaceae) has a widespread distribution, extending from western Europe to eastern Asia. In Europe, it usually behaves as a spring-germinating biennial species. Ripe seeds of T. japonica have an underdeveloped embryo and can persist in the soil for several years.

Seed Germination in Soil: Dormancy Cycles
2017The soil seed bank consists of numerous seeds, many of which are dormant and delay germination until a later time. The persistent portion of the soil seed bank is a major source of future plants. Certain plant species emerge during the same season of each year.

The Role of Temperature on the Dormancy Cycle of Seeds of Rumex obtusifolius L.
Functional Ecology, 1989Seeds of Rumex obtusifolius L. were buried at different depths in bare soil, under a grass turf and under shrubs. The temperature was measured daily at seed level. During 3 years, monthly samples were exhumed and the germination was tested at different temperature regimes. The dormancy levels follow a seasonal pattern.

Dormancy/Nondormancy Cycles in Spores of the Liverwort Sphaerocarpos texanus
The Bryologist, 1999The presence of a dormancy/nondormancy cycle was investigated in spores of the winter, annual, liverwort, Sphaerocarpos texanus. To test for loss of dormancy, mature laboratoryderived spores were held at three daily alternating incubation temperature regimes (thermoperiods) of 35/20, 30/15, and 25/15?C.
