Tracing the research with plants seems to bring me back to Les Brown in Canada during the 1970's - I am yet to find someone earlier who documented this work to such an extent. It comes up briefly in the work of Patrick Flannagan but that came out in the 80's I believe.
The other question to explore, who showed or explained to these people about all of this.
Thank you for this. Very interesting indeed.
