Spore Cleaning:All chaff must be carefully cleaned from the spores. Storage Conditions: Spores are kept dry and stored in a refrigerator. |
||
| Pre-Planting Treatments: | Carefully sterilize growing media, flats and flat coverings before sowing spores. | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Greenhouse. Spores are sown on petri plates with ditilled water and sealed in a sterile ziplock bag. |
||
| Establishment Phase: |
After spores germinate, the prothalli are placed on sterile 3:1 Peat/Perlite mix in rectangular flats. Flats are covered with glass to seal in moisture. Water only with distilled water. |
||
| Active Growth Phase: |
Once fertilization occurs and the developing sporophytes at least 1 true leaf, they are potted into individual containers (2 or 4 inch) containing standard potting mix of peat moss, fir bark, perlite, and sand. Plants should be grown in shade. |
