What promotes blooming?

Hi all,

Well, we have accumulated quite a list of factors that may influence 
blooming in various species.  What I've gleaned from the discussion so far:

1.  Maturity

2.  Photoperiod

3.  Moisture

4.  Temperature

5.  Fire/smoke

6.  Changes in weather (i.e., barometric pressure changes, ionization of 
the air, presence of nitrogen oxides from lightning, rain itself)

Did I overlook or forget anything?  The same factors that influence 
flowering can also influence seed germination as well.  We should probably 
keep in mind that any plants that have been grown in cultivation for many 
generations are likely to lose their dependances upon some of the natural 
factors, depending on how they have been selected down through the 
years.  Dutch hybrid amaryllis bulbs do not behave quite the same way that 
wild Hippeastrum species bulbs behave, for instance.   For one thing, they 
are vastly easier to grow and to get to flower!
