Let me add to Fred's statement. Nikita's Gift (Nikitskaya Bordovaya) is 
Rosseyanka (Rossey) back crossed to kaki. As far as I know Rosseyanka was the 
first world's hybrid and maybe still the only 50/50 V x K. I have seen no 
claims of more original hybrids although the Japanese have been trying and 
may 
have succeeded by now. Rossey was one of about a dozen seeds that embryo 
rescue was used on and Rosseyanka the only one that survived. Dr. Pasenkov 
who 
is the originator wrote he used many years Double Mentoring. That is, each 
was grafted onto the other species, the virginiana seed parent onto kaki and 
the kaki pollinator onto virginiana. Then embryo rescue was used. All my 
attempts without mentoring failed.

Hi All,
I am germinating persimmon seeds but their seed coats just don't want to sp=
lit and release the cotyledons. In previous years I've tried to cut them bu=
t it results in too much damage to the little plants.
Any suggestions on how I encourage them or should I stop worrying?

Karl
