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. Cones are 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, (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: 4,620, Purity: 99%, X-Ray 100 Seeds: 96% Filled, Moisture Content: 7.2%
