Physical dormancy in Geraniaceae seeds / Anke Meisert (2002)
Titre : Physical dormancy in Geraniaceae seeds Type de document : Tiré à part de revue Auteurs : Anke Meisert (1969-) Année de publication : 2002 Importance : 121-128 Langues : Anglais (eng) Catégories : [CBNPMP-Thèmes] Dormance Mots-clés : Erodium manescavii Cosson Geraniacées Résumé : Seed dormancy was analysed in Geraniaceae, testing 29,103 seeds of 35 species for seed-coat impermeability to water. Seeds of wild and cultivated species from a number of different climatic/ecological zones (northern Germany, the Canary Islands and South Africa) were investigated. Seeds from cultivated plants and natural populations had similar (±2%) percentages of water-impermeable seeds. The percentages of impermeable seeds at maturity were also mostly constant (±2%) for two different years. The species analysed contained from 0 to 100% impermeable seeds at maturity, and could be classified into three quantitative types of physical dormancy: four species with no impermeable seeds (PY0), 10 species with a maximum of 80% impermeable seeds (PY80), and 21 species with more than 80% impermeable seeds (PY100). Species with different life cycles and from very different habitats, e.g. Geranium pratense or Pelargonium capitatum, belonged to the PY100 group. However, all of the succulent shrubs investigated from the genus Pelargonium were PY0 species. Five years of dry storage at 20 ± 5°C decreased physical dormancy in a species-dependent fashion. Erodium cicutarium, for example, had 95% impermeable seeds at maturity; all of them became permeable during the dry storage and began to germinate immediately after placing them on a moist substrate. Physical dormancy of other species, e.g. Pelargonium zonale, Pelargonium vitifolium or Geranium pratense, was not affected by dry storage. Thus, physical dormancy is a diversely differentiated feature in Geraniaceae with regard to both percentages of impermeable seeds at maturity and maintenance of dormancy under particular conditions.

[CBNPMP-Thèmes] GrainesMots-clés : Allium Résumé : Many New World Allium L. (Amaryllidaceae) species exhibit seed and bulb dormancy characteristics that are responsive to environmental factors such as temperature, soil moisture and photoperiod. This review is intended to discuss perspectives on the adaptations and mechanisms of dormancy and provide a current summary of research in the area of seed germination, bulb dormancy initiation and bulb dormancy release in Allium species found in North America.

Titre : Seed dormancy in Asteraceae: a global vegetation zone and taxonomic/phylogenetic assessment Type de document : Imprimé Auteurs : Carol C. Baskin ; Jerry Mack Baskin Année de publication : 2023 Article en page(s) : 135-169 Langues : Anglais (eng) Catégories : [CBNPMP-Thèmes] Dormance Mots-clés : Asteraceae Résumé : The Asteraceae with up to 30,000 species occurs on all continents except Antarctica and in all major vegetation zones on earth. Our primary aim was to consider cypselae dormancy-break and germination of Asteraceae in relation to ecology, vegetation zones and evolution. Cypselae are desiccation-tolerant and in various tribes, genera, species and life forms of Asteraceae are either non-dormant (ND) or have non-deep physiological dormancy (PD) at maturity. All six types of non-deep PD are found among the Asteraceae, and dormancy is broken by cold or warm stratification or by afterripening. Soil cypselae banks may be formed but mostly are short-lived. Much within-species variation in dormancy-break and germination has been found. Using data compiled for 1192 species in 373 genera and 35 tribes of Asteraceae, we considered ND and PD in relation to life form, vegetation zone and tribe. Senecioneae and Astereae had the best representation across the vegetation zones on earth. In evergreen and semi-evergreen rainforests, more species have ND than PD, but in all other vegetation zones, except alpine/high-latitude tundra (where ND and PD are equal), more species have PD than ND. Tribes in the basal and central grades and those in the Heliantheae Alliance have both ND and PD. The high diversity and lability of non-deep PD may have enhanced the rate of species diversification by promoting the survival of new species and/or species in new habitats that became available following globally disruptive events since the origin of the Asteraceae in the Late Cretaceous.
