| Family Scientific Name: | Apiaceae | ||
|---|---|---|---|
| Family Common Name: | Carrot Family | ||
| Scientific Name: | Perideridia bolanderi (A. Gray) A. Nelson & J. F. Macbr. | ||
| Common Name: | Olasi, Yampah | ||
| Ecotype: | Sage, perennial grass; Elko Co., NV | ||
| General Distribution: | Dry to moderately moist, sometimes gravely, open hillsides and dry washes, from California and southern and eastern Oregon to western and northcentral and extreme southern Idaho (Oneida and Bonneville counties). Across central and northern Nevada to Utah (Box Elder and Juab counties), and western Wyoming (Lincoln and Teton counties). | ||
| Known Invasiveness: | Not invasive. | ||
| Propagation Goal: | plants | ||
| Propagation Method: | seed | ||
| ProductType: | Container (plug) | ||
| Time To Grow: | 0 | ||
| Propagule Collection: | The white flowers in compound umbels bloom in late May to mid-June. The fruit (a schizocarp) is mature when it turns brown and dehisces readily. We collected seed in late June to mid-July, approximately four to six weeks after flowering. Fruits were collected by hand stripping. Seed was placed in various porous storage containers (paper bags, woven polypropylene bags) and stored with a small (1" by 2") piece of Hot Shotr "No-Pest Strip" containing Dichlorvos (2,2-dichlorovinyl dimethyl phosphate) 18.6% to kill insect pests, then spread out in a warehouse until dried. | ||
| Propagule Processing: | Fruits were delicate, so were not put through a de-bearder. The mericarps usually separate during drying, and simple passage through a blower removed extraneous material. Clean seed was transferred to paper envelopes or woven polypropylene bags. Seed stored up to three years was still viable. | ||
| Pre-Planting Treatments: | We tested germination by placing 25 apparently whole, filled seeds on moist blotter paper in petri dishes (4 repetitions). Dishes were sealed inside closeable plastic bags to reduce desiccation, placed in a -2øC germinator for two weeks, and then held at +2øC. Germination commenced in 10 weeks, but most seeds germinated by 16 weeks. Germination rates ranged from 16 to 46%. For a larger plug production, approximately 500 seeds of each accession were dusted with Captanr fungicide powder and stirred into moist peat moss in closeable plastic bags, and placed in a +2øC germinator. Bags were checked weekly or daily until germinants were observed over a 12 week period, at which time seedlings were planted in the greenhouse. | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Seedlings were carefully pricked into soil mix (2 parts sieved peat: 2 parts Vermiculite: 1 part Agsorbr or Turfacer (montmorillonite clay): 1 part #20 quartz silica sand, plus fertilizer and micronutrients) in 1«" x 1«" x 5«" deep seedling tubes. Greenhouse temperatures ranged from 15-22øC. Flats were irrigated as needed to keep roots moist. Seedlings had an 80% survival rate. | ||
| Establishment Phase: |
All accessions of this species failed to develop true leaves for the first growth phase. The cotyledons thickened and remained photosynthetic, and after two months, senesced. At that stage, we found each plant had developed a small (1/4") round root storage section (tuber or "biscuit") 1" beneath the soil surface. The roots also appeared to have senesced. The "biscuits" remained intact and healthy yet dormant for 28 weeks in flats in the greenhouse, where they received occasional irrigation. They were field planted as tubers in early spring. Some tubers had begun to sprout both new stems and roots. Most individuals in most accessions developed a single true leaf about one month after field planting. The true leaves senesced after two-three months. In 2006, the second field year, we will observe whether the individuals that developed true leaves will put out a greater number of leaves. |

| Length of Establishment Phase: | Unknown; possibly longer than one year. | ||
