| Propagule Collection: | Seed was hand collected in mid-summer in 2009 by BLM botany technicians. Seed was placed directly into brown paper bags. A small piece of No-Pest Strip was placed in each bag for 2-3 days to reduce insect predation. Seed was air dried in paper bags at room temperature. | ||
| Propagule Processing: |
According to Nita Rauch, USFS Bend Seed Extractory, seed lots of this species have been cleaned as follows: 1.) F.S. Missoula Dewinger: Hopper Feed = 15, black liner, tilt = 3 & speed = 5 for about 1 hour. 2) OEM Continuous Seed Blower: Set on Low (= 300) for 40 minutes. Seed can be cleaned to a purity of 96%-98%, with seeds ranging from 168,000-187,400 per pound. Using x-ray equipment, 80% of the seeds in lot SOS-931-117-09 were filled. |
||
| Pre-Planting Treatments: | Seed was stored at room temperature in a dark location prior to sowing. | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Sowing Method: Each seed was scarified by swiping once across a fingernail file. Seed was then soaked in distilled water at room temperature for 20 hours. Of the 600 seeds, more than 50% germinated while soaking. Two to three seeds were sown ¬ inch deep in each container. Potting soil was a 2:1:5 mix of lava fines, perlite, and Sunshine Mix #4. Chicken grit was spread on the surface of each container. Containers were hand watered and placed outside on April 16th. No fertilizer was added to the soil mix. | ||
| Establishment Phase: | 40%-50% of the seed resulted in established seedlings. | ||
| Length of Establishment Phase: | About 2 months | ||
| Active Growth Phase: | Containers were allowed to dry slightly between hand watering. A weak fish emulsion fertilizer was applied twice a month from April through June. Plants were grown outside in full sun until outplanting in early October. Some seedlings were dormant by mid-September. | ||
| Length of Active Growth Phase: | 4 months | ||
| Other Comments: | Plants were not permitted to flower while in the nursery. Flower stalks were removed as soon as they were observed. We produced a total of 255 plants from the 600 seeds. Nine inch containers were used because of the long taproot. | ||
