Re: Genes


I agree.  Just because you can do something, does not mean that it is the
thing to do.  If someone puts daylily flowers on Hosta without defeating the
system that makes the flowers last only one day would, I think, be a fool.
Hmm..  Why has no one fixed this problem in daylily?

On the trigger temperature for Anthocyanin pigments.  I would suspect that
it would be different for different species.  The levels of the pigment are
usually tied to the balance of carbohydrates in the plant tissue.  Plants
are adapted to different temperature optimums, so the balance points would
vary between species.

Another point that might help the hybridizer.  The ability to control the
level of anthocyanins is also under genetic control.  Look at Japanese
maples where there is a tremendous difference between varieties in their
ability to stay red at warmer temperatures.  I would suspect that it would
be wise to select for both increased amounts of red color, and for heat
tolerance for pigment levels.
