I was really just thinking aloud, and grossly simplifying the situation in the process....there is not much agreement on what causes adventitious root growth even after all this time and a great many well funded research and PhD projects!!!

There is a reasonable amount of sound material out here on the net, that can provide you with a working understanding of the various factors that it is agreed can be (and in specific cases are) critical in the emergence and growth of adventitious roots.

Like almost all aspects of growth in plants, palms or trees, it is driven monitored and managed through hormonal (chemical) checks and balances. Loss of connecivity between the existing roots and the canopy directly impacts on the status of the chemical growth control in place within the plant..I quess thats what I was getting at.
