Seed Dormancy and Germination [PDF]
The Arabidopsis Book, 2008 Seed dormancy allows seeds to overcome periods that are unfavourable for seedling established and is therefore important for plant ecology and agriculture. Several processes are known to be involved in the induction of dormancy and in the switch from the dormant to the germinating state.

Seed dormancy and germination [PDF]
Current Biology, 2017 Reproduction is a critical time in plant life history. Therefore, genes affecting seed dormancy and germination are among those under strongest selection in natural plant populations. Germination terminates seed dispersal and thus influences the location and timing of plant growth.

Seed dormancy and the control of germination [PDF]
New Phytologist, 2006 SummarySeed dormancy is an innate seed property that defines the environmental conditions in which the seed is able to germinate. It is determined by genetics with a substantial environmental influence which is mediated, at least in part, by the plant hormones abscisic acid and gibberellins.

STUDIES IN SEED DORMANCY [PDF]
New Phytologist, 1967 SummaryThe dormancy of hazel seeds (Kent cob nuts) has been found to be broken by less than 30 days chilling at 5° C. During 50 days chilling there was no detectable growth of the embryonic axes although growth rapidly commenced when the temperature of 50‐day chilled seeds was raised to 20° C.Both cotyledon slices and embryonic axes from dormant seeds ...

Proteomic Analysis of Seed Dormancy in Arabidopsis [PDF]
Plant Physiology, 2006 AbstractThe mechanisms controlling seed dormancy in Arabidopsis (Arabidopsis thaliana) have been characterized by proteomics using the dormant (D) accession Cvi originating from the Cape Verde Islands. Comparative studies carried out with freshly harvested dormant and after-ripened non-dormant (ND) seeds revealed a specific differential accumulation of

Seed Coat Development and Dormancy [PDF]
, 2007 Two major types of dormancy mechanisms exist: embryo dormancy where the agents inhibiting germination are inherent to the embryo, and coat-imposed dormancy where inhibition is conferred by the seed envelopes (Bewley, 1997). Generally, complex interactions between the embryo and covering structures determine whether a seed will germinate.

MECHANICS OF DORMANCY IN SEEDS
American Journal of Botany, 1916 Dormancy in plants is common in three organs, seeds, spores, and buds. In this paper I shall limit myself entirely to the discussion of dormancy in seeds for three reasons: far more critical and analytical work has been done on dormancy in seeds than upon the other two organs; obscure correlation effects do not play as prominent a part as in buds; and ...

Seed dormancy in alpine species
Flora - Morphology, Distribution, Functional Ecology of Plants, 2011 In alpine species the classification of the various mechanisms underlying seed dormancy has been rather questionable and controversial. Thus, we investigated 28 alpine species to evaluate the prevailing types of dormancy. Embryo type and water impermeability of seed coats gave an indication of the potential seed dormancy class.

Seed Dormancy: Induction, Maintenance and Seed Technology Approaches to Break Dormancy
, 2022 Dormancy is the major cause of erratic germination, patchy emergence and uneven seedling establishment in the field. These traits are exceedingly undesirable in crop production as future phases of growth and development are strongly linked to uniform seedling development at early growth phases.

Engei Gakkai zasshi, 1965 1. Small seeded varieties of Spanish and Valencia types showed only shallow dormancy just after harvest, but large seeded varieties of Virginia type showed deep dormancy continuing during rather long period.2. Differences of nature of dormancy due to difference of growing areas between Japan and Israel could hardly been observed.3.
