Alleviation of Salt-induced Seed Dormancy in the Perennial Halophyte Crithmum Maritimum L. (apiaceae)
Crithmum maritimum L. (Apiaceae) is a perennial local oilseed halophyte. For a better understanding of the eco-physiology of salt tolerance at the germinative stage of this species, we investigate here the effects of nitrate, thiourea, and priming on its seed germination under saline conditions. Germination was strongly inhibited by increasing salinity. While nitrate supply was effective in all...
متن کاملSeed Heteromorphism and Effects of Light and Abiotic Stress on Germination of a Typical Annual Halophyte Salsola ferganica in Cold Desert
Seed heteromorphism is a common characteristic of halophyte and an adaptation to the spatial and temporal variations of natural habitats. Differences in dormancy and germination requirements have been documented in heteromorphic seeds of many species, but the mechanisms for maintenance between different status in various populations have not been well-understood. Salsola ferganica is a typical ...
متن کاملComparison of germination and seed bank dynamics of dimorphic seeds of the cold desert halophyte Suaeda corniculata subsp. mongolica.
BACKGROUND AND AIMS Differences in dormancy and germination requirements have been documented in heteromorphic seeds of many species, but it is unknown how this difference contributes to maintenance and regeneration of populations. The primary aim of this study was to compare the seed bank dynamics, including dormancy cycling, of the two seed morphs (black and brown) of the cold desert halophyt...
متن کاملPollen Germinability and Cross-Pollination Success in Persian Cyclamen (Cyclamen persicum Mill.)
Low seed yield is a limiting factor for cross breeding and hybrid seed production in cyclamen. This study was performed to investigate pollen germination and its relation to cross-pollination success and fruit set in this plant. In order to achieve a high level of pollen germination, the effect of different concentrations of chemical compounds were examined on in vitro pollen germination of cyc...
متن کاملNutrients, arbuscular mycorrhizas and competition interact to influence seed production and germination success in Achillea millefolium
1. Environmental variables that positively affect one aspect of plant fitness, may have no effect, or even negatively affect some other component of fitness. 2. Using individuals of Achillea millefolium grown under field conditions in Michigan, USA, the hypothesis was tested that seed number was determined largely by plant biomass, while seed germination success depends on tissue nutrient conce...
