Dormancy and germination characteristics of Tarenaya hassleriana (Cleomaceae) seeds
Journal of Seed Science, 2023 : Elucidating the physiological and ecological mechanisms of seed dormancy and germination is of great significance for species conservation and the application of plant resources. Based on Baskin and Baskin’s classification system for seed dormancy, the

Transcriptomic analysis of American ginseng seeds during the dormancy release process by RNA-Seq. [PDF]
PLoS ONE, 2015 American ginseng (Panax quinquefolius L.) is an important herb that is cultivated in China, North American, and South Korea. It is propagated from seed, but the seed has deep dormancy characteristics described as morphophysiological dormancy.

Genomic imprinting regulates establishment and release of seed dormancy
Current Opinion in Plant Biology, 2022 Seed dormancy enables plant seeds to time germination until environmental conditions become favorable for seedling survival. This trait has high adaptive value and is of great agricultural relevance. The endosperm is a reproductive tissue formed after fertilization that in addition to support embryo growth has major roles in establishing seed dormancy.

BMC Plant Biology, 2021 Background To adapt seasonal climate changes under natural environments, Polygonatum sibiricum seeds have a long period of epicotyl morphophysiological dormancy, which limits their wide-utilization in the large-scale plant progeny propagation.

Dormancy release, ABA and pre-harvest sprouting
Current Opinion in Plant Biology, 2005 Seed dormancy is an adaptive trait that enables the seeds of many species to remain quiescent until conditions become favorable for germination. Dormancy is normally initiated during seed maturation and maintained to seed maturity. In mature seeds, the loss of dormancy may be gradual (after-ripening) or can be terminated by chilling and other ...

CYTOLOGICAL STUDIES IN DORMANCY III. CHANGES DURING LOW‐TEMPERATURE DORMANCY RELEASE [PDF]
New Phytologist, 1972 SummaryThe cytological changes occurring in dormant embryo radicle meristem cells of Fraxinus excelsior during the period of chilling before germination are described. The only events observed to be dependent on low temperature occurred in the nucleolus, which increased in volume and complexity of structure.

CYTOLOGICAL STUDIES IN DORMANCY II. PATHOLOGICAL AGEING CHANGES DURING PROLONGED DORMANCY AND RECOVERY UPON DORMANCY RELEASE [PDF]
New Phytologist, 1972 SummarySeeds with a chilling requirement were maintained fully imbibed at 22–25° C for more than 6 years without germination. Similar seeds stored air‐dry at the same temperatures were dead by the second year. Cytological changes in the radicle meristem cells during the first year included the development of complex associations of ER with protein ...

Expression Analysis of the MdCIbHLH1 Gene in Apple Flower Buds and Seeds in the Process of Dormancy
Horticultural Plant Journal, 2016 A bHLH transcription factor that is induced by low temperature was found in apple (Malus × domestica Borkh.). To understand the sequence characteristics of the gene, bioinformatics analysis was performed.
