The above propagation data sourced from Claude AI
Pre-treatment: Shoot tips were defoliated and surface sterilized for 20 min in a 1% solution of NaClO, then rinsed 3 times in sterile distilled water. Rooted propagules were removed from sterile, glass tubes and the roots were gently washed under running water to remove any remaining agar.
Establishment: This species of Hackelia is only found in Chelan County in the Washington Cascade Mountain Range. The protocols do not provide information on germination rates or times, or specific temperature requirements.
