[NAFEX] Persimmon Seed Dormancy Anomaly

The only value I can see in such seedlings is that they *might* produce 
trees that need less chilling than normal.  Useful in the south, but 
not much value anywhere else.
	Otherwise, that premature sprouting shows up in other plants.  I've 
seen apple and grape seeds that did that, too.  Most seeds contain 
substances that inhibit dormancy until the substances are broken down 
by cold.  Such instant sprouting seeds probably either somehow didn't 
get the substance, or have embryos that are "resistant" to the 
substance.

I have noticed that about 1% of the fresh persimmon seeds I have are 
sprouting with no stratification. I thought they would need at least 90 
days worth.

Anyone know if this is normal?

Would there be any disadvantage or even advantage to isolating these 
individuals for any purpose?

Would these particular seedlings be good for grafting later on?

Perhaps if they were bred together a line of persimmons could be bred 
whose seeds would need no stratification at all?
