No, I think what Poe meant to say was that the growth rate is ultimately
limited by the physiology of the plant which is determined by genetics. Also
don't forget about Crypts which could be likely to get more nutrients &
light than they can use. A simple doubling or tripling of chromosome pairs
can produce a much faster growing plant. Crypts are genetically programmed
to grow slowly! Do they do it using physiology or is there a trickier
chemical limit? They must be doing it to exploit an ecological niche; low
