Perennial Life Style of Populus: Dormancy Cycling and Overwintering
2009Deciduous trees in boreal and temperate areas are strictly conditioned by the environment, especially by photoperiod and temperature. However, it is in particular the successful submission to these conditions that has rewarded them with long-life spans.

Sensitivity cycling and its ecological role in seeds with physical dormancy
Seed Science Research, 2009AbstractCycling of physically dormant (PY) seeds between states insensitive and sensitive to dormancy-breaking factors in the environment has recently been demonstrated inFabaceaeandConvolvulaceae, and it may be a common phenomenon in seeds with water-impermeable seed coats.

The Banjhi (Dormancy) Cycle in Tea (camellia sinensis)
Experimental Agriculture, 1981SUMMARYThe ‘banjhi’ or dormancy cycle in free-growing tea trees appears to be the result of an endogenous rhythm. However, in harvested tea apical dominance causes dormant shoots to be produced under conditions favourable to growth, and the synchronized flushing cycle causes periods of apical shoot (active terminal bud) and secondary shoot (dormant ...

Production of Seed Samples for the Effective Molecular Analysis of Dormancy Cycling in Arabidopsis
2011Most often, the samples used for molecular analysis of dormancy are populations of seeds. An essential survival characteristic of seed populations inhabiting the variable surface layers of the soil is that individuals in the population do not behave uniformly. In addition, seed dormancy (SD) status of the whole population constantly changes even in the

Seed Science Research, 2001
Cell cycle activities are initiated following imbibition of non-dormant seeds. However, it is not known whether cell cycle related events other than DNA replication also remain suppressed in imbibed dormant seeds. The objective of this study was to demonstrate that the transitions between the non-dormant and dormant (both primary and secondary) states ...

Dormancy cycle and viability of buried seeds of Papaver rhoeas
Weed Research, 2006SummarySeeds of three Spanish Papaver rhoeas populations (two resistant to both tribenuron‐methyl and 2,4‐dichlorophenoxyacetic acid and one susceptible to both herbicides) were buried at 2, 8 and 20 cm depth in Lleida (Catalonia, Spain). At various intervals up to 77 months they were exhumed and tested for germination in an agar medium and for ...

Dormancy and Power On-Off Cycling Effects on Electronic Equipment and Part Reliability [PDF]
, 1973 Abstract : Two 12-month programs were conducted. The first was to collect, study, and analyze reliability information and data on dormant military electronic equipment and parts and to develop current dormant failure rates, factors, and prediction techniques.

Growth and Dormancy Cycles in Citrus Bud Cultures and Their Hormonal Control
Physiologia Plantarum, 1974AbstractAn in vitro bud culture method was devised in order to better understand the control mechanism of Citrus bud development. This technique offers a new approach to the study of hormonal control of growth, dormancy and flowering cycles in perennial plants.Buds were excised from orchard trees throughout the year, cultured on defined media for ...

The control of bud dormancy cycle in fruit trees
2022Dormancy is an essential developmental program that allows tree adaptation to low temperatures in winter. The mechanisms that regulate dormancy are highly heritable, suggesting a strong genetic control of this trait. However, the genetic networks controlling dormancy cycle in trees are still unknown.

Distinct roles of MADS-box complexes in the control of the dormancy cycle in apple
2021Dormancy is an essential developmental program that allows tree adaptation to low temperatures by inducing a bud resting state until the end of the winter. After a prolonged cold period, buds reactivate growth in response to the warm temperatures of the spring.
