| Summary: | Pinguicula vulgaris L., Primula farinosa L., Saxifraga hirculus L. and Swertia perenms L. are rare extinct species, protected byjntema- tioiial and national legal acts m numerous European states. Seeds of this plant species were collected in the natural habitats of Lithuania and germination of these seeds was checked in laboratory Dunng experiments significance of seed stratification, substrate and light for seedlings was studied. The least seed germination is characteristic of Pinguicula vulgaris: approximately 3-4 of seeds havegermmated during studies. Seeds of Saxifraga hircuhis germinated best (50 ). The first seedlings appeared after 10 days on average. Germination of stratified seeds was faster, but stratification had no influence on the number of germinated seeds. Seed germination depended especially on hydrological regime and type of substrate. Seeds of Pinguicula vulgaris germinated better on sand. Peaty substrate and mineral soil were the most suitable for seed gemunation o Saxifraga hircuhis and Primula farinosa. On filter paper seeds of all species germinated worst. Influence of the light on seedling is diffe- rent as well. |
