Germination Information
Pre-treatment: Seeds require cold, moist stratification. Preliminary trials indicate that seeds are dormant and this dormancy is not broken with dry storage. Ethylene treatment can improve germination rates. Seeds can also be chilled and frozen before ethylene and stratification treatment.
Establishment: Seeds are collected when the inflorescence is dry and the achenes are dark brown to black. Shattering is usually not a problem but the seeds are subject to bird and animal predation. Insect damage can also be extensive. Seed is stored in paper bags at room temperature until cleaned. A strict seed collection mandate of removing less than 5% of a population in each collection area was followed. Seed was hand harvested in five separate locations. Because of possible variation in seed due to elevation and geographical differences, harvesting was very site specific: geographical locations similar to each other and to the field-transplanting site were selected.
