“…Temperature regimes over 25°C tended to induce seed dormancy, with delay in both germination time and final germination percentage (94% at 25°C, 50% at 30°C); a 50% germination is also reported at 25°C and 12/12 h photoperiod by Royal Botanic Gardens Kew (2019). These results are in accordance with those given by Luciani & al. (2001), who studied germina-tion behaviour of this species related to temperature, salinity and after-ripening time, assessing an optimal germinability (98%) at 15°C (full darkness and distilled water), and a seed dormancy induction with both rising temperature (> 20°C) and salinity (> 0.1 M NaCl), but basically overcome by longer after-ripening time.…”

Medit. 29: 277-287. 2019. https://doi.org/10.7320/FlMedit29.277This study investigated seed germination in nine psammophilous species occurring in Sicilian sand dunes, some of which, such as Muscari gussonei, Launaea resedifolia and Pancratium maritimum, are endemic and/or rare and very scattered in the area. Different germination protocols were tested for one or more populations and the best germination results per species are provided, reporting experimental conditions and specific comments on the germination behaviour.

“…The effect of the relationship between salinity and increasing temperatures on germination behavior of halophilic species has been highlighted in other typically Mediterranean halophytes. These include Briza maxima (Lombardi et al 1998) from wild populations in a brackish lagoon in Tuscany; Plantago coronopus living behind the dunes in southeastern Sicily (Luciani et al 2001); Crucianella maritima (Del Vecchio et al 2012); Limonium insigne growing in southeastern Iberian Peninsula (Fernández et al 2015); Cakile maritima from central Italy, Sardinia, and Mallorca (Del Vecchio et al 2018); Limonium supinum an endemic halophyte from Iberian Peninsula (Melendo and Giménez 2019), but also in other non-Mediterranean climates such as Salsola vermiculata from the Canary Islands (Guma et al 2010), Urochondra setulosa (Gulzar et al 2001), Phragmites karka (Zehra and Khan 2007), and Zygophyllum propinquum (Manzoor et al 2017) from Pakistan or Suaeda maritima from British salt marshes (Seal et al 2018).…”

The study of the ecological strategies adopted by seed plants to ensure their success in different environments is closely related to germination ecology. This implies a careful knowledge of ecophysiology of seeds and, therefore, also of interaction between plants and the complexity of external factors. In particular, the environmental conditions of the area where a plant grows and produces seeds represent the main factors that influence successful seedling establishment. The physical-chemical features of habitats, and therefore their heterogeneity, affect the behavior of seeds in different ways. In addition to the timing of seed production, they can induce or terminate dormancy and/or germination and influence the germination pattern of different seeds in the same plant and so the composition and dispersal of soil seed banks. Salinity is a major abiotic stress affecting growth and plant productivity worldwide, constituting one of the main topics of study in the field of plant physiology. Halophytes are the plants that have the availability to survive and develop in different types of saline habitats. In this chapter, we consider some examples to illustrate the main adaptive strategies used by the seeds of halophytes on ecophysiological perspectives to survive in habitats affected by high levels of salinity. The focus is on the species that live in the

“…the initial germination process is delayed under salt stress (Keiffer & Ungar 1997;Almansouri et al 2001;Gorai & Neffati 2007). A high salt concentration in the soil can prevent germination, and seeds may germinate when temperature and edaphic conditions become favourable (Vleeshouwers et al 1995;Khan & Ungar 1997;Luciani et al 2001). Morphological features of seeds usually show ecological adaptation to environments where their mother plants naturally occur (Song et al 2005;Zhang et al 2010;Minuto et al 2011).…”

Relationships between ion and chlorophyll accumulation in seeds and adaptation to saline environments in Suaeda salsa populations

The importance of ion and chlorophyll accumulation was evaluated in brown seeds of a Suaeda salsa population from an intertidal zone and one from a saline inland zone during seed development. The results showed that more NO 3 7 and K þ , but less Cl 7 and Na þ in leaves and stems were translocated to the embryos in the intertidal population than the inland population; more Cl 7 and Na þ were compartmentalized in the pericarps of the intertidal population compared to the inland population, which indicates that the two populations have different ability to accumulate ions in different plant parts. The embryos of fresh premature seeds contained chlorophyll and the embryos could release oxygen. The content of chlorophyll markedly decreased, and there was no oxygen production in the embryos of dry mature seeds in both populations. These characteristics may affect the distributions of the two S. salsa populations in their natural saline environments.
