Activity Report
1. ISTA Tetrazolium Testing Working Sheets
The major achievement of the Tetrazolium Committee over the last triennium has been the publication of the New ISTA Tetrazolium Handbook. The Handbook takes the form of Working Sheets and is in two Volumes. Volume I deals with Agricultural, Vegetable and Horticultural Species and Volume II covers Tree and Shrub Species. The Working Sheets are in loose-leaf format and additional sheets can be added as methods for new species are developed and validated. The working sheets will prove an essential tool to any worker or laboratory engaged in Tetrazolium testing and thanks are due to the authors/editors Norbert Leist, Stefanie Krāmer and Andrea Jonitz. A special word of mention goes to Jochen Pfāfflin for his exceptional illustrations.
2. Organisation of International Workshops
In addition to their superb work on the Working Sheets the LUFA Augustemberg laboratory of Norbert Leist have also been engaged in organising International Tetrazolium Workshops. In July and August 2002 they organised a workshop at their laboratory in Karlsruhe (Germany). There were almost 30 participants from Argentina, Brazil, Belgium, Denmark, France, Germany, Greece, Italy, Ireland, Latvia, Slovenia, Switzerland, The Netherlands, United Kingdom, USA, and Yugoslavia. Practical work focused on Lotus corniculatus, Glycine max, Helianthus annuus, Hordeum vulgare, Lolium sp., Oryza sativa, Tagetes sp and Zea mays.
Norbert Leist and Stefanie Krämer in conjunction with Prof. Dr. Warren H. J. Kou from the Seed Laboratory of the National Taiwan University have organised a Tetrazolium workshop that will take place in March 2004 in Taipei. Also scheduled for June 2004 is a workshop in the United States of America that is being organised by William Johnston.
3. Method development
In 2001 a questionnaire was sent to all the ISTA Accredited Seed Laboratories and the same questionnaire appeared on the ISTA Web-site. Response was tremendous and suggestions for method development and comparative testing of more than 100 species were received. Working Group Leaders were appointed and every TZ Committee member was tasked with developing a TZ method for at least one species. Despite this progress has been disappointing with no working group or committee member providing information of any progress.
4. Proficiency Testing
The first ISTA TEZ Proficiency test in the new scheme will take place in February 2004. Wheat seed samples are being prepared by the Ronald Don and in conjunction with the Moisture Committee who will be using the same samples for their second proficiency test. |
