HYB: daylength vs temperature & bloom initiation


From: Linda Mann <lmann@icx.net>

I guess this is mostly a question for Dave Holm -
What's the interaction between daylength and temperature & effects on
bloom initiation?
I'd love to hear more about this - you mentioned initiator hormones as
well as inhibitors - could there be a daylength 'motivator' in addition
to the dormancy period or is it more likely to be varying dormancy
(inhibitor?) requirements?  What's going on with these hormones while
the plant is dormant?   What's it up to?  What does it have to finish
with before it can start growing again?  Are there cultural things I can
do to "trick" it into taking longer?  Are there temperature thresholds
or is it a cumulative amount of warmth?

I guess that's maybe enough questions for one day...
