(I dont know what Viacao Aerea Riograndense means?)

Anyway, The only sex cells or gametes will be in the ovaries, which become the banana fruit after the pollen from the stamens in the flowers is transferred to the pistils and fertilization occurs. It has nothing to do with grafting and grafting will never produce any type of mutation or hybrid mix between 2 plants. It just doesnt work that way. If you will do some simple research into this you will see that it just cant happen. "I expect them to in some way exchange gametes, that is, complete sexual cells and change their characteristics." How would this happen? Thats a pretty big leap of thought there. These sexual cells or gametes arent just floating all around inside the banana plant magically mixing themselves up to produce a different plant. Thats like saying if you take a piece of a person and mix it up with a piece of another person, that you should expect that it should somehow produce a hybrid or a mutation. Im sorry, but this will never occur through grafting. The photos of the flowers above just look like older ones in the first photo and new ones in the second, or perhaps Raja Puri flowers in the first photo and Basjoo flowers in the second.
