Germination Information
Pre-treatment: 6-month cold moist chilling in a refrigerator maintained at 34 to 37°F
Establishment: Germination does not decrease with decreasing light intensity from full to partial, but declines substantially from full and partial irradiance to zero. Seedling mortality is high in the partial and zero irradiance treatments.
