All of the above! I've certainly gotten to a point where I recognize seed that I work with a lot and also keep records on longevity when it comes to germination as well as the taxonomy such structure pertaining to seed coat thickness, breaking dormancy etc. The main problem with longevity is how they are stored.
I have never come across a single place or found a single book that addresses everything .. it's always piecemeal. If you are planning to write one, please sign me up (and I'll be hoping for an autographed copy).
