| Family Scientific Name: | Oleaceae | ||
|---|---|---|---|
| Family Common Name: | Olive | ||
| Scientific Name: | Chionanthus pygmaeus Small | ||
| Common Name: | Pygmy Fringe Tree | ||
| General Distribution: | Florida | ||
| Known Invasiveness: | non-invasive, endangered | ||
| Propagation Goal: | plants | ||
| Propagation Method: | seed | ||
| ProductType: | Container (plug) | ||
| Time To Grow: | Weeks | ||
| Propagule Collection: | 2012 - ripe seed collected - fruits at the raisin stage, dark brown/black and shriveled. | ||
| Propagule Processing: | remove flesh of fruit, carefully crack and remove endocarp | ||
| Pre-Planting Treatments: | immediately plant in damp well drained media in warm sunny location | ||
| Establishment Phase: | after 1 month when taproots have all formed, germinated seed is stratified in refrigerator for 90 days | ||
| Length of Establishment Phase: | 90 days | ||
| Active Growth Phase: | after stratification phase, plant seeds with taproots, 1 per plug, into plug trays filled with well drained media. Keep moist, not wet and in high light until shoots form (approximately 60 days) | ||
| Other Comments: |
This protocol gave almost 80 percent germination. Other protocols were attempted, hot water soaks, cold stratification immediately after removing endocarp, sowing whole seed. germination ranged from 0 percent (cold stratification and whole seed), to 50 percent (hot water soak) Asan addendum - in 2013 - a set of fruits picked while still in the firm "green olive" stage to just starting to turn brown was tested. The same protocol that gave the most successful results (listed below) was utilized. Germination and formation of primary taproot was reduced to only 8.5 percent. |
