I think where the bubbles comes from might have something to do with the leaf thickness. But as far as i know the photosynthesis rate of the plant is what controls bubbling ability.
my wendtii has traditionally been one of my heaviest pearlers in tanks with Hygro difformis Hemianthus umbrosum Limnophila Aromatica Rotala green etc... Wendtii has had a tendency when in full light to pearl as much if not more then these.
