[gdlr_heading tag=”h2″ font_weight=”bold” ]Our Purpose[/gdlr_heading]

The purpose of the AOSA/SCST Referee Committee is to provide a forum for the cooperative implementation of projects related to seed testing among a number of seed laboratories.  These projects are chosen and developed in order to fulfill one or more of the following purposes:
1) To promote standardization and improvement in seed testing;
2) To provide opportunities for feedback, training and continuing education to seed analysts;
3) To address issues of concern within a specific area of the Seed Industry and to identify areas where more research is needed; and
4) To test new methods and gather data in order to support a Rules change proposal.

Regional co-chair(s): Sue Alvarez and Bob Price

1. Project: Sandberg Bluegrass Germination
   Contact: Terry Freeman
   Purpose: To assess the methods for sandberg bluegrass and use of kno3 to break dormancy.
2. Project: Quinoa germination methods
   Contact: Sue Alvarez
   Purpose: To assess germination protocols for quinoa to add the crop to AOSA rules. ISTA has a proposal this year to add this species (tp, BP, 20C, 4 day first count, 7 day final count) and and 15C has been suggested as a variable temperature.
3. Project: Hemp Dormancy Study
   Contact: Randy Crowl
   Purpose: To assess the effectiveness of prechill in breaking dormancy in freshly harvested hemp seed.
