| Family Scientific Name: | Apiaceae | ||
|---|---|---|---|
| Family Common Name: | Parsley family | ||
| Scientific Name: | Lomatium triternatum (Pursh.) Coult. & Rose. | ||
| Common Name: | Nine-leaf biscuitroot | ||
| Ecotype: | Malheur County, Oregon, 1399 m | ||
| General Distribution: | Open slopes and meadows, dry to fairly moist soils from the lowlands to mid montane; southern Alberta and British Columbia to Colorado, Utah and California. | ||
| Propagation Goal: | plants | ||
| Propagation Method: | seed | ||
| ProductType: | Container (plug) | ||
| Time To Grow: | 0 | ||
| Propagule Collection: | Yellow flowers occur as early as March or April and as late as May. Phenology varies based on elevation, aspect and seasonal weather patterns. The fruit (a schizocarp) is mature when it turns brown and dehisces readily. This typically occurs 5 to 8 weeks after flowering. Fruits are collected by hand stripping from the compound umbels into containers. | ||
| Propagule Processing: | After collection, the fruit was thoroughly dried and placed in a standard freezer for 48 hours to remove insect pests. It was then cleaned by passing it through a «" chicken wire screen mesh, hand picking larger stems and debris, and screening the remainder through a #8 STS (Standard Testing Sieve). After the seed was cleaned, it was spread over a light table and those with irregular uniformity or density were discarded. It was stored in a brown glass bottle at room temperature for 18 months prior to propagation trials. | ||
| Pre-Planting Treatments: | One hundred and fifty seeds were soaked in water for 24 hours, placed in clear plastic germination boxes on two layers of blotter paper, thoroughly moistened with distilled water, and placed in a germinator at 4§C in the dark for a 60-day prechill. Blotter paper was remoistened periodically as needed. 93% of the viable seed germinated. Tetrazolium (TZ) tests (Idaho State Seed Laboratory) determined that 92% of the seeds were live. | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Upon first signs of germination, seeds were sown 1 cm deep in styrofoam conetainers with a 50% peatand 50% vermiculite mixture. Containers were watered from an automatic overhead irrigation system which turns on when soil saturation levels fall below 80% and turns off when 100% field capacity is reached. Greenhouse temperature was a constant 27§C. Small amounts of fertilizer suitable for seedlings were added periodically. | ||
| Establishment Phase: | Germination began after 36 days of cold moist treatment. The majority germinated within the first 13 days, but continued sporadically for 67 days. True leaves appeared after 14 days. The seedlings were in the greenhouse for 77 days. Survival was about 53%. | ||
