Then there are also climates that get a fair amount of rain year round, and those species may have more "grow now" instructions written into its DNA. Then there are the seriously cold environments in Asia like China where Mussellea lasiocarpa comes from, and that species has "need winter chill" written into it's DNA.
All of these environments are found in the areas that Musa is native to, so it would seem likely that they have developed/evolved to their specific environmental conditions.
Just some thoughts.
