Dormancy-breaking and germination requirements of seeds of four Lonicera species (Caprifoliaceae) with underdeveloped spatulate embryos / Siti Nur Hidayati (2000)

Public Citation est un tiré à part de 10 - 2000 (Seed Science and Technology) Titre : Dormancy-breaking and germination requirements of seeds of four Lonicera species (Caprifoliaceae) with underdeveloped spatulate embryos Type de document : Tiré à part de revue Auteurs : Siti Nur Hidayati ; Jerry Mack Baskin ; Carol C. Baskin Année de publication : 2000 Importance : 459-469 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Dormance [CBNPMP-Thématique] Maturation des semences [CBNPMP-Thématique] Techniques de germination Mots-clés : Lonicera Résumé : Dormancy-breaking requirements and types of dormancy were determined for seeds of Lonicera fragrantissima Lindl. & Paxt., L. japonica Thunb., L. maackii (Rupr.) Maxim. and L. morrowii A. Gray. Seeds of all four species have underdeveloped spatulate embryos that are about 20–40%fully developed (elongated) when dispersed. Embryos in freshly matured, intact seeds grew better at 25/15°C than at 5°C. Gibberellic acid (GA3) (tested only in the light) was more effective in breaking dormancy in L. maackii and L. morrowii than in L. fragrantissima and L. japonica. Warm- followed by cold stratification was required to break dormancy in seeds of L. fragrantissima, whereas seeds of L. japonica required cold stratification only. Thus, seeds of L. fragrantissima have deep simple morphophysiological dormancy (MPD) and those of L. japonica nondeep simple MPD. About 50%of the seeds of L. maackii required warm- or cold stratification only to come out of dormancy and 50% of those of L. morrowii required warm stratification only, whereas the other 50% did not require stratification to germinate. Thus, about half of the seeds of the two species has nondeep simple MPD, and the other half has morphological dormancy (MD). In these laboratory tests, seeds of L. japonica, L. maackii, and L. morrowii generally germinated to significantly higher percentages in light than in darkness; seeds of L. fragrantissima were not tested in darkness. Peaks of germination for seeds of L. fragrantissima, L. japonica, L. maackii and L. morrowii sown on a soil surface and covered with Quercus leaves under near-natural temperature conditions shortly after seed maturity and dispersal in late June 1997, late November 1997, early November 1996 and late June 1998, respectively, occurred in early March 1998, late February 1998, late March 1997 and early October 1998, respectively. The germination phenologies of seeds of the same species and seed lots buried in soil were similar to those of seeds under leaf litter. High percentages of seeds of all four species germinated both under litter (78–96%) and beneath the soil surface (78–97%). These germination patterns correspond closely with the requirements for embryo growth and dormancy break in the four Lonicera species.

Effects of dry storage on germination and survivorship of seeds of four Lonicera species (Caprifoliaceae) / Siti Nur Hidayati (2002)

Public Citation est un tiré à part de 30 - 2002 (Seed Science and Technology) Titre : Effects of dry storage on germination and survivorship of seeds of four Lonicera species (Caprifoliaceae) Type de document : Tiré à part de revue Auteurs : Siti Nur Hidayati ; Jerry Mack Baskin ; Carol C. Baskin Année de publication : 2002 Importance : 137-148 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Conservation des semences [CBNPMP-Thématique] Germination : généralités Mots-clés : Lonicera Résumé : Effects of dry storage under ambient laboratory conditions on germination and survivorship was tested for seeds of four Lonicera species. Fresh seeds of L. fragrantissima and L. japonica were dormant, whereas those of L. maackii and L. morrowii germinated to about 30% at 25/15°C in light. Seeds of L. fragrantissima remained dormant during the entire 24 months of storage. Highest germination for seeds of L. japonica, L. maackii, and L. morrowii were 47, 68, and 50%, respectively, in light after 6 months storage. Decrease in germinability between 6 and 12 months storage for L. japonica and L. maackii, and between 6 and 15 months for L. morrowii was greater than decrease in viability; thus, some seeds re-entered dormancy. However, for seeds of L. japonica and L. maackii stored longer than 12 months, decrease in viability was greater than decrease in germinability, indicating that more seeds after-ripened than lost viability. Survivorship curves for seeds of all four species were approximately Deevey Type II. A graphical model is presented for the roles of re-entrance into dormancy, loss of viability, and after-ripening in determining germinability of seeds.

Seed dormancy in Asteraceae: a global vegetation zone and taxonomic/phylogenetic assessment / Carol C. Baskin in Seed science research, 33 (2) (2023) 

Public Citation [article]  inSeed science research > 33 (2) (2023) . - 135-169 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-Thématique] 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.
