Propagation Collection:
Cones are removed from trees and stored in bushel size burlap bags.

Propagation Processing/Propagule Characteristics:
METHOD OF PROCESSING: The bags of cones are pre-dried on racks in a well ventilated indoor storage area. Cones are then kiln dried, at 100 Degrees Fahrenheit for 15 hours, until flared. Conesare then tumbled to extract the seeds. Seeds are then de-winged using a Mortar/Mixer De-winger with approximately 1 quart of water. Seeds are then air-screened, using a Clipper Eclipse, Model 324, with a top screen, 15 to 18 round and a bottom screen, 6 round, medium to high air, (screen sizes and air varies by lot). Seeds are finished using a Gravity Separator, Oliver Model 30, (speed and air varies by lot), to remove remaining nonviable seed and inert material. Number of Seeds per Pound: 10,460, Purity: 99%, X-Ray 100 Seeds: 94% Filled, Moisture Content: 7.1%
