Somebody knows a seller who can tell precision ? or maybe I m wrong and we dont have to worry about it ?


Special thanks to Lorax for the seeds picture that can help well.

And Birdie youre right for the deadseeds have been sold too much time, but I ve no choice Ive to go on (I dont know why, dont ask).

Other question but facultive one or bonus ; does somebody know if cultivated seeds from a specie growing in a cooler place than his birthsplace can arise the coldtolerance ? fast (1 or 2 generations) or does it takes about 1000 years to expect some changes.
Well, I would like to answer your question with the mail I sent you today. Read on.

Yes, even one generation can bring results. But only if the plant is almost unprotected and its natural abilities are stimulated. Let me demostrate by another curiosity in my area. Palms that were grown from seedlings are way better, than those brought to our country from outside (mostly Trachycarpuses, but I'm trying also others, from seeds of course). They adapted to our winds, lots of water in winter (freeze, melt, freeze, melt...) and they do not rot, break, their leaves freeze at lower temps than usually and can withstand our eniroment. Their terminal temperatures moved only about by a 1°C, but it certainly did... I don't see why this would work different with bananas. It is however carefully planned culture and the plants must be trained in generations, not suddenly.
Also please note, that bananas include lots of water and grow incredibly fast. This plays against them. Lots of water means, that its limits will be low, no matter the time (water in air and plants starts freezing at 2°C - snow), or they will learn how to "get dry and dormant for freezing temps on their own". Also the fast growth is against them. Palms and other plants, that grow slowly, but surely, make lots of mutations in their life and pass them ALL on their next generation (and naturally only the best and most dominant characteristics are transferred during pollination). However bananas will grow significantly faster and thus mutate less in one genaration. In time you may find out, that most of /if not all your hardier bananas die in your experiments over time...

In conclusion: Yes, it is possible, but very long long long process. For palms it is about half the human life, for naners I don't dare to say.
And that's why I like doing it.
