Family Scientific Name: Polygonaceae
Family Common Name: Buckwheat family
Scientific Name: Eriogonum racemosum
Common Name: Pink Smoke
Species Code: ERIRAC
Ecotype: Utah 1610 to 2580m
General Distribution: E. racemosum is found in the Southern Rocky Mountain states.
Propagation Goal: plants
Propagation Method: seed
Time To Grow:
Propagule Collection: E. racemosum flowers in mid to late summer and seeds ripen in late August to late September, 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 5.5 to 6.1 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. racemosum showed high doramncy without prechilling but only required an 8 week prechill to become completely non dormant. Its germination rate in the cold was intermediate(10 to 14 wks to 50%).
