Description
Agenda
This half-day workshop aims to provide analysts with training on:
- Principles of conducting referee and research studies.
- Applications of tolerances and interpretations.
- How to use the Excel calculator to determine purity/noxious weed weight and seed count for new species.
Participants will be guided in developing methods and procedures for addressing objectives and protocols of referee and research studies, as well as proper applications of tolerances and their interpretation.
Participants are encouraged to propose specific topics for discussion before or during the workshop.
Referee/research studies (R. Baalbaki; 1:00-2:15pm)
- Principles of referee testing: objectives, hypothesis, and types of tests.
- Referee testing for proposing new rules or revisions to existing rules.
- Referee test applications: purity, germination, and other tests.
- Excel calculation of purity weight & seed count for new species (2:15-2:45pm).
Break: 2:45-3:00pm
Tolerances application and interpretation (S. Elias; 3:00-5:00pm)
- Principles and applications, non-chaffy, chaffy, super chuffy, and native tolerances.
- Effects of sample size and seed quality on tolerances – probability of errors – one sided and two-sided tolerances. Comparing label with a second test.
- Tolerances for purity and germination components (pure, other crop seed, weed seed, inert, normal, abnormal seedlings, and dead seeds).
- Tolerances of mixture of seeds of different sizes.
- Tolerances for fluorescence test and other tests using morphological traits.
- Tolerances for vigor tests such as AAT and EC.
- Open discussion and conclusion of the workshop.
