Family Scientific Name: Poaceae
Family Common Name: Grass
Scientific Name: Elymus glaucus
Common Name: Blue Wildrye
General Distribution: Open areas, chaparral, woodland, forest; greater than 7,500 feet.
Propagation Goal: seeds
Propagation Method: seed
ProductType: Propagules (seeds, cuttings, poles, etc.)
Time To Grow: 0
Propagule Collection: Collected in the Yosemite National Park.
Propagule Processing: EASE OF COLLECTION: Data unavailable at date of publication.
METHOD OF CLEANING: Seed cleaned using Model 47-B clipper using topscreen, 1/14 X 1/4; middle screen 1/16 X 1/4; bottom screen 1/14; at 100% air full open. Hammered with 1/4" screen at 700 revolutions per minute.
TYPE OF MATERIAL COLLECTED FOR PROPAGATION: Seed.
PROPAGATION METHOD: Was planted at the the Lockeford Plant Materials Center as field seed increase.
NUMBEROF SEEDS PER POUND: Data unavailable at date of publication.
PERCENT GERMINATION: 91%.
Pre-Planting Treatments: PRETREATMENT USED: None required.
Growing Area Preparation/
Annual Practices for Perennial Crops:		 METHOD OF GROWING: Planted at a seeding rate of 10.5 pounds per acre, 30" rows (the two-acre stand seeded on February 15, 1989 was rated as excellent). This species was established using standard methods, i.e., disking, land leveling, furrows, planting with drill, fertilizing, cultivating, and spraying for weed control, and irrigation. This stand demonstrated that high elevation blue wildrye grass seed can be produced in large quantities at 100' elevation in the Mediterranean climate.
Harvesting, Storage and Shipping: SEED MATURITY DATE: Late June.

UNUSUAL OR UNIQUE HARVESTING OR DIGGING REQUIREMENTS: (In both 1990 and 1991) Harvested with three passes with a flail-vac harvester at 300 revolutions per minute (RPMs); in 1990, 120 pounds were bulk-harvested, which yielded 43 pure live seed pounds (21 .5 PLS pounds/acre), 91 % germination, 99.89 purity. In 1991, 558 pounds were harvested, which yielded 250 pounds of clean seed; the seed test results are not in at this time. The pesticides used on this stand are MCPP with Buctril and Redeem.

STORAGE REQUIREMENTS: Longevity of seed unknown. No known special storage requirements.

ESTIMATED PROPAGULE STORAGE POTENTIAL: Data unavailable at date of publication.
