| Family Scientific Name: | Liliaceae | ||
|---|---|---|---|
| Scientific Name: | Allium cernuum | ||
| Common Name: | Nodding Onion | ||
| Species Code: | ALCE2 | ||
| Ecotype: | Colorado,Sprague Lake (98-004s), Long's Peak Parking Lot (98-092s), Twin Sisters (98-082s), Alluvial Fan (98-093s) | ||
| Propagation Goal: | seeds | ||
| Propagation Method: | seed | ||
| ProductType: | Propagules (seeds, cuttings, poles, etc.) | ||
| Time To Grow: | 0 | ||
| Propagule Collection: |
Collected at Sprague Lake on 09/16/98, Long's Peak Parking Lot on 10/07/98, Alluvial Fan on 09/21/98, Twin Sisters on 09/21/98. Seed cleaning technique: Small black seeds simply removed from papery covering. Many seeds are not filled and are easily crushed, these won't germinate. |
||
| Propagule Processing: | Germination: 50-75% at Sprague Lake. | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Propagation Environment: Greenhouse, 65-70§F day/55§F night. Propagated on the heating pad (set at 70§F) under tent with misters set 8 am-8 pm, with 10 sec/15 min watering intervals. One week after germination, seedlings were moved to mister area without tent. Germination media: Fafard Germinating Mix (superfine). Growing media:>/b> Fafard Growing Mix 2. |
||
| Establishment Phase: |
Sowing/planting technique: Manually sowed in seed pack flat, 2-3 seeds/slot, cover seed lightly with germination mix. Time to germination: 14 days. Establishment Phase: Germination uneven and occurs over many days. Sprague Lake sowed on 10/27/98 emerged on 11/10/98; Long's Peak Parking Lot sowed on 11/18/98, emerged on 11/30/98; Alluvial Fan sowed on 11/18/98; Twin Sisters sowed on 11/12/98, emerged on 11/30/98. |
||
| Harvesting, Storage and Shipping: | Seed storage condition: Seed stored in the greenhouse. | ||
