Family Scientific Name: Poaceae
Family Common Name: Grass family
Scientific Name: Koeleria macrantha (Ledeb.) Schult.
Common Name: Prairie Junegrass
Species Code: KOMA
Ecotype: BLM, Seeds of Success: USFS land, Site 1, Betensen Flat, Piute County, Utah: 9640 ft. elevation
Propagation Goal: seeds
Propagation Method: seed
ProductType: Propagules (seeds, cuttings, poles, etc.)
Time To Grow: 0
Propagule Collection: Very small lot, 0.23 pounds, hand collected into cloth bag.
Propagule Processing: METHOD OF CLEANING: Seed lot is first processed using a Westrup Model LA-H laboratory brush machine, with a solid mantel, at a speed of 3, to remove seed from stems and de-awn. Seeds are then air-screening, to remove chaff and inert material, using an office Clipper, with a top screen: 14 round and a bottom screen: 50x50 wire mesh,low speed, and low air. Lot was finished by hand under a microscope. Number of Seeds per Pound: 1,890,000 Purity: 89%, X-Ray 100 Seeds: 80% Filled
Harvesting, Storage and Shipping: Storage: Cold Storage, 33-38 Degrees Fahrenheit
Other Comments: With Prairie Junegrass not all native ecotypes produce viable seed. Many ecotypes generally go through anthesis, but not all will produce viable seed at an economically acceptable level. This equates to low yield.
