Seed dormancy and germination of Taraxacum mongolicum
Taraxacum mongolicum is a famous Chinese herbal medicinal plant and a popular ecological species. Experiments were conducted in the laboratory and greenhouse to study the seed germination and seedling emergence characteristics of this species. Results suggested that seeds of T. mongolicum were not dormant. Greatest germination occurred at 20°C and germination was inhibited at temperatures below 5°C or higher than 35°C. Temperature fluctuation caused an increase in seed germination percentage and rate. Germination of T. mongolicum seeds was insensitive to light. Seeds of T. mongolicum are fairly tolerant to water stress and dry soils during germination. High osmotic potential (< -0.4 MPa) and low soil water content (< 20%) inhibited seed germination. Results can provide guidance for nursery propagation and direct seeding strategies of T. mongolicum.
