TLDR
Germination of the polymorphic seeds and seedling growth of Atriplex triangularis under various salinity, gibberellic acid and kinetin treatments were determined.
Abstract
Germination of the polymorphic seeds and seedling growth of Atriplex triangularis under various salinity, gibberellic acid and kinetin treatments were determined. Gibberellic acid (GA3; 2.9 mM) promoted germination and growth at high NaCl concentrations (345 mM). Kinetin (4.7 μM) stimulated germination at all salinities and seed sizes tested. GA3 and kinetin generally increased seedling growth at all concentrations of salinity studied. Higher concentrations of kinetin were found to be inhibitory.

Evaluating germinability of eight desert halophytes under long-term seed storage: Implications for conservation

TL;DR: Evaluated ex situ storage potential of eight halophytic species from deserts in the United Arab Emirates by studying seed germination, finding that fresh seeds of seven of the eight species tested had a higher germination rates under 12/12 h light/dark fluctuations than did those exposed to total darkness.

Overexpression of a RNA silencing suppressor, B2 protein encoded by Flock House virus, in tobacco plants results in tolerance to salt stress

TL;DR: Transient assays using point mutant and deletion constructs indicate that functional RSS activity is not required for salt tolerance, and demonstrates the importance of host RNA silencing activity in imparting stress tolerance.

Factors controlling germination and dormancy processes in dimorphic fruits of Atriplex inflata (Chenopodiaceae)

TL;DR: In some species belonging to the Asteraceae, Chenopodiaceae, Poaceae and Brassicaceae, a single individual produces different morphophysiological types of seeds that differ in colour, size, shape, germination and dormancy, known as seed dimorphism or seed polymorphism.

Comparative effect of NaCl and seawater on germination of quinoa seed (Chenopodium quinoa willd)

TL;DR: In this article, the effect of NaCl and seawater, compared to a control with distilled water, on the seed germination of Chenopodium quinoa were investigated, and the radicles were the most affected by salt stress compared to hypocotyls.

Palatability of salt marsh forbs and grasses to the purple marsh crab (Sesarma reticulatum) and the potential for re-vegetation of herbivory-induced salt marsh dieback areas in cape cod (Massachusetts, USA)

TL;DR: The results suggest that S. reticulatum prefers Spartina alterniflora over forbs and that one or all of these forb species are good candidates for vegetation restoration in dieback areas.

The effect of salinity and temperature on the germination of polymorphic seeds and growth of atriplex triangularis willd.

TL;DR: Polymorphic seeds of Atriplex triangularis were germinated at various temperatures and salinity regimes and the rate and percentage of germination decreased with increased salinity stress, and early seedling growth in larger seeds at lower salinity and at high-day and low-night temperatures.

Hormonal Control of Germination under Saline Conditions of Three Halophytic Taxa in the Genus Suaeda

TL;DR: The results indicate that gibberellic acid is capable of breaking dormancy in these species with dormant seeds, but kinetin proved to be ineffective.

Salinity, temperature, and growth regulator effects on seed germination of Salicornia europaea L.

TL;DR: Although S. europaea is the most salt tolerant of the species growing on the salt pan in which it occurs, an increase in salinity stress proved to be inhibitory to seed germination for all temperature regimes investigated.

Water potential, temperature, and kinetin effects on seed germination in soil and solute systems.

TL;DR: Germination in soil and solute systems was compared to determine the usefulness of solute germination data for predicting germination in dry soil and concluded conclusions about the effects of water stress at one temperature are not valid at other temperatures if a water stress-temperature interaction exists.
