  9. 9. Priming Protocols <ul><li>Grass seed </li></ul>
  10. 10. Sanitation Technologies <ul><li>Our aim is to sanitize the seed while at the same time to improve the germination of the seedlot : </li></ul><ul><ul><li>Wet Sanitation (wet film, vapor) </li></ul></ul><ul><ul><li>Priming Sanitation (in priming type processes) </li></ul></ul><ul><ul><ul><li>Short duration </li></ul></ul></ul><ul><ul><ul><li>Longer duration </li></ul></ul></ul><ul><ul><li>Large scale sanitation (for larger volumes – new project) </li></ul></ul><ul><ul><ul><li>Min. capacity of large scale sanitation is 500 kg/1000 lbs per hour. </li></ul></ul></ul><ul><ul><li>Electron beam seems too expensive </li></ul></ul><ul><li>Level of sanitation (depending on the problem): </li></ul><ul><ul><li>Surface sanitation </li></ul></ul><ul><ul><li>Deep sanitation (incl. embryo) </li></ul></ul>
  11. 11. Sanitation Technologies <ul><li>Canola Sanitation for Xanthomas c.c. and other pathogens (in general a better germination possible) </li></ul>
  12. 12. Sanitation Technologies <ul><li>Fusarium infected tomato related species: </li></ul><ul><li>PR = control (primed) </li></ul><ul><li>S1 – S4 are 4 different sanitation treatments </li></ul><ul><li>Later additional treatments were applied. </li></ul><ul><li>Further potential candidates available. </li></ul>
  13. 13. Sanitation Technologies <ul><li>Fusarium infected tomato related species: </li></ul><ul><li>PR = control (primed); Left </li></ul><ul><li>S5 is new sanitation treatment </li></ul><ul><li>Germination speed and Good Plants: </li></ul>Object   1 d 2 d 3 d 4 d 5 d 6 d primed   20 48 70 72 78 80 primed + San5  15 50 90 98 100 100 Object   Usable Pl. 1st Qlt 2nd Qlt Abn No Germ primed   80 60 20 0 20 primed + San5 98 80 18 2 0

  18. 18. Sanitation Technologies <ul><li>Corn Sanitation for Fusarium and other pathogens </li></ul>
  19. 19. Biological Technologies <ul><li>Aim to control some pathogens and saphrophytes during the treatment, possibly reducing mycotoxins at harvest. </li></ul><ul><li>And especially to reduce the chance for re-infection after germination </li></ul><ul><li>Endophytes to fill intracellular spaces (e.g. Bacilllus spp to control re-infection with Fusarium spp) </li></ul><ul><li>Trichoderma spp to cover the root system externally. </li></ul><ul><li>Mycorrhizeae </li></ul><ul><li>By: </li></ul><ul><li>Priming-based inoculation </li></ul><ul><li>Coating based inoculation </li></ul><ul><li>Additives </li></ul><ul><li>Controlled drying processes </li></ul>
  20. 20. Technologies for Parentlines (Seed Production) <ul><li>Aim is to clean the seed as much as possible, even if the result is some drop in germination. </li></ul><ul><li>Vernalization of parentline seed in cold dependent species for improvement and synchronization of flowering </li></ul><ul><li>Sanitation of parentline seed for clean start of seed production </li></ul><ul><li>By: </li></ul><ul><li>Priming type processes </li></ul>
