Jim,
There is a molecular test recently developed by a
Japanese group that allows pollen-constant, non-astringent asian persimmons to
be identified at the seedling stage (http://www.actahort.org/books/622/622_16.htm).
Not sure if it would work with American persimmons. There also is a similar
marker found in kiwifruit that can sometimes identify male seedlings. These
tests are based on DNA sequences that are closely linked to the determining
genes. Unfortunately, this test requires using PCR (polymerase chain reaction)
to amplify the target DNA sequences using a rather expensive thermal cycler.
This would be rather routine for a university research lab, but certainly not
the simple test that a backyard grower or nurseryman could use. I am not aware
of any morphological or cellular features that could be observed to determine
sex, other than the actual flowers.
