Well...nobody really knows for sure. Some Musa seeds actually germinate at a higher percentage when stored for a few months, while others do much better when "fresh." The problem there is that the seeds from that study were of an unknown species, and no such data exists for specific species. I have read articles where seeds that were taken out of fresh fruit, cleaned and sown, germinated at a much higher percentage as seeds from the same species that came from a rotten or dried fruit. So, I imagine that if you were to harvest seeds from a fresh fruit, they would be considered fresh until they dried out. When they are allowed to dry out is when they go somewhat dormant (some go very dormant!). If you are planning on trying to germinate them right away, then they should be sown immediately after cleaning them of the fruit. In order to store them properly, they need to be dried out to 10% seed content moisture. This pretty much just involves letting them set out for about 2 days to dry. If they are stored before they dry out sufficiently, the length of time of their viability is reduced drastically (only a few weeks)! I think ideally, the seed dealers would ship them moist, having never let them dry out. When a few weeks have passed, or some start germinating, then they should let them dry out properly to store them and keep them viable.

That all being said...I don't know! LOL! Hope that answers your question.?!
Really, it all depends on the conditions of the seeds from the time that they are harvested. If harvested from fresh fruit, dried and stored properly, they should stay "fresh" for many months. If not, who knows?
