Here in the U.S. we are mostly confused about the meaning of "frost" and "freeze". So "frost" is something that can appear on objects and plants around 4.5C (40F) or lower, and freezing is something that we all agree happens at 0C (32F).

So when you said "subjected to frost", you meant ... ? If it was freezing temperatures, then wow, the plants held up very well.

I know you've cut leaves etc. of banana plants before, so your aware of the "holding cells" of water in the plant, not to mention the overall high density of fluids throughout the plant structure. When that freezes all the way through for any significant time (1+ hour), the biology is in serious trouble.

So how much cold can a banana take? It's an experiment in cryogenics!
