Title Seed dormancy and germinability in the halophyte Halosarcia pergranulata subsp pergranulata
Source Seed Science and Technology
Author Keywords salt tolerance; germination; polymorphism
Abstract The effect of scarification on seed germination in the succulent halophyte, Halosarcia pergranulata subsp. pergranulata, was studied. H. pergranulata subsp. pergranulata was found to have a partial physical dormancy attributable to the testa, a phenomenon rare among halophytes. Dormancy was alleviated by scarification of the testa. This was most effective where it occurred near the radicle. Incidental coverage of the micropyle by the hilum in some seeds did not affect germinability.
