Physiological effects of chilling Tulip bulbs

Here is an article on the effects of pre-chilling tulip bulbs http://wwwlib.com/

Note that it is *not* the initiation of the flower bud which is effected,
it is the shoot growth, it's rate of growth to flowering, and the
production of offsets. Perhaps, in warmer climates, the increased speed of
growth may be critical to get the Tulips to flowering before summer aborts
the buds with premature dormancy?
I failed to get Tulipa sprengeri to flower from seeds several times. It
dives very deep in the pots and the bulbs would not get bigger. pPanting
pots of two year old seedlings in the ground was much more successful.

Since I prechill the tulips
I grow every year since it doesn't get very cold here and otherwise
they don't bloom, I've never been sure what to do with seedlings and
have just left them in the pots in the shade until they were bigger
so perhaps that too could be a problem. This year the sprengeri bulbs
I still have left (the survival rate has not been good) are in the
refrigerator with the rest of my tulips, but they are very small.

Mary Sue,
I also live in Southern California, Orange County. I used to keep tulipbulbs in floral refrigerator
in fall before planing them in December. It is too warm to set flowers
here.
