Found the paper. No mention of height of measurement whatsoever.
I did assume that it was taken at the base because, it looks to me, this is the only "point of interest" where datas can be confronted no matter what, but i can see your reasons.
Actually, in forestry, measurements are taken, as standard, at 130 cm from the ground. In this case that height has been chosen for easiness and to take measurements quicker. In bananas this doesn't seems so necessary (as far as i know) because i assumed that, outside from scientific studies, banana measurements are pretty uncommon?
