The above propagation data sourced from Claude AI
Pre-treatment: Divisions: placed into Vitamin B-1 solution for 15 minutes. Seed: sown into cone-tainers filled with Sunshine # 1, amended with micro-nutrients and a slow-release fertilizer. Flats covered with polyethylene bags and placed in a walk-in cooler for 5 weeks.
Establishment: No significant differences in emergence or seedling vigor were noted between 5, 10 or 16 week stratified seeds. 0 germinants were observed in control flats.
