TOW seed dormancy - Alstroemeria

Diane: Are the days to germination (emergence) that you posted, the
number elapsed from the beginning of the outdoor (5 to 10 C)
period? excluding of course the 4 weeks of 18 C. Roy
No. I counted the days to emergence from the time I sowed the
seeds. So, for example, A. philippiana germinated 10 days from the
time sown. Any of my seeds that germinated in 30 days or less
germinated in the warmth of my kitchen or living room and never had
a cool period except for the slight drop each night when I turned
the heat down.
That beats anything I saw 4 years ago when I tried germinating
without chilling, on a mist bench at high temps (20 to 23 C). Got to
do that again. I don't have many seed of species (just a few of
aurea and ligtu that I collect annually) but I have oodles of hybrids
sitting around.
