Propagation Collection:
Very small lot, 0.11 pounds, hand collected into cloth bag.

Propagation Processing/Propagule Characteristics:
METHOD OF CLEANING: Seed lot is first processed using a Westrup Model LA-H laboratory brush machine, with a #40 mantel, at medium speed, to remove seed from capsule, and to remove the silky hairs from the tiny seed. Laboratory Test Sieves, mesh size 50, 40, & 20 were used next to remove non seed material. Seeds are then air-screened, to remove remaining chaff and inert material, using an office Clipper, with a top screen: 40 x 40 wire, and a bottom screen: 50 x 50 wire, (2nd run, blank), low speed, and low air. Number of Seeds per Pound: 11,340,000, Purity: 80%, X-Ray 100 Seeds: 80% Filled

Other Comments:
Fireweed is a challenge to clean due to the tiny seed and the silky hairs, (that aid in wind dispersal), which makes this seed "flighty" and difficult to feed into the brush machine. Very small seed lots present a cleaning and testing challenge. Different types of equipment, designed for smaller lots, are used.
