| Family Scientific Name: | Polygonaceae | ||
|---|---|---|---|
| Family Common Name: | Buckwheat family | ||
| Scientific Name: | Eriogonum corymbosum | ||
| Common Name: | Lacy buckwheat | ||
| Species Code: | ERIALA | ||
| Ecotype: | Utah 880 to 1700 m | ||
| General Distribution: | E. alatum is found in the Colorado Plateau and Uinta Basin. | ||
| Propagation Goal: | plants | ||
| Propagation Method: | seed | ||
| Time To Grow: | |||
| Propagule Collection: | E. corymbosum flowers in late summer to fall and seeds ripen in late September to early November, depending on elevation. | ||
| Propagule Processing: |
Seeds are cleaned by hand rubbing material through a 2 mm round hole screen. Caff is removed from seed by using a tabletop model blower. Achenes are stored at 20 to 22C with 30 to 40% relative humidity in paper envelopes until mid October. Achene mass averages 1.0 to 1.2 mg per 100 achenes. |
||
| Pre-Planting Treatments: |
6 prechilling treatments were used: 0,2,4,8,12,16 and 24 weeks of moist chilling at 2C in the dark. |
||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Following chilling treatments, seeds were incubated 4 weeks under a daily temperature and photoperiod regime (12hr dark at 10C and 12hr light at 20C)with a cool flourescent light. Achenes were placed in disposable petri plates on 2 blue germination blotter papers moistened with tap water. Blotter papers were re-moistened as needed. |
||
| Establishment Phase: | Results and Discussion:E. corymbosum showed germination response patterns that were problably related to habitat temperature. Two collections from low elevation, warm sites near Moab and Saint George, Utah germinated completely after a 4 wk chill and were fast to germinate in the cold (5 to 8 weeks to 50%), while a collection from a higher elevation, more northerly site on the San Rafeal Swell required 8 weeks of chilling to break dormancy completely and was much slower to germinate in the cold (16 wks to 50%). | ||
