And which plant species are these?

BTW, the idea is not a new one.

Have you heard something about electrotropism in plant? Recently I have
met
a profesor who proved (he said that) that in some plant species, influence
of atmospheric electrical field is stronger than gravity field. Is that
effect known? I'd like to make sure that he was really first (or not).
