Seed dormancy and germination of an endangered coastal plant Eryngium maritimum (Apiaceae)
Eryngium maritimum is a coastal plant of the Apiaceae family. This species is threatened in several countries where it reaches the northern limits of its distribution area. Existing populations in the Baltic Region and Scandinavia are potentially affected by the low efficiency of its generative reproduction. We studied physiological aspects of its germination and dormancy breaking requirements ...

متن کاملIn Vitro Production of Bulblet in Galanthus transcaucasicus Fomin, an Endangered Medicinal Plant
To optimize conditions for micropropagating Galanthus transcaucasicus Fomin, the effect of explant type, different concentrations of sucrose, type and different concentrations of auxin were examined on bulblet production. For the induction of bulblets, three types of bulb scales were usesd as explants. A two-step sterilization procedure was applied. Assessments were made after incubation for 20...
