Germination Information
Pre-treatment: Seeds require a 5-6 month outdoor cold, moist stratification. They are surface sown for light requirement. Germination occurs at 18 C (64.4 F). Germination was greater in light than in dark.
Establishment: Seeds are collected when achenes turn tan in mid to late August. Seed capsules are cut from plants using scissors and are collected in paper bags. Seeds are kept in a well ventilated drying shed prior to cleaning. Germination decreased with decreasing light intensities. High seedling mortality at full and partial irradiance levels was observed, but there was a measurable gain in germination of the zero irradiance treatments when exposed to a secondary full irradiance.
