No, Tobias did not germinate the seeds, but he knows this paper. You are right
, Markku Häkkinen is the best person to ask him how to break the dormancy of the seeds, he should answer here in this thread! I will request him by PN. We are interesting how to break the dormancy to get finally the seedlings and plants of these rare and very new banana species to self grow in our yards and greenhouses.
I also wrote him one email recently about this, some hours ago, but he should see this thread and post here for us all. I know that here are many members who already sown these species without success. He might help us.
Best wishes
Joachim
