Interesting, Jonathan. I've found that tomatoes retain pretty good germination abilities for up to 10-11 years, even if stored with no special temp or moisture considerations. I keep my saved seed in snap top plastic or screw cap glass vials in my office - this year I had 60-90% germination on seed saved from 2006. Next year I am going to do a sizeable planting of seed I saved in 1989-91 just to see what I can get to germinate.
