If OS is polyembryonic, does that mean that ALL of your seedlings will be true OS? I'm not sure how that works. (Five minutes later)...OK, I found this:
"A polyembryonic seed contains multiple embryos, so produces more than one shoot, actually several shoots depending on the number of embryos. Only one of the shoots originates from fertilization which is not a true clone of the parent seed. All the other seedlings are clones of the mother tree. The fertilized seedling is weak and should be discarded.
The fertilized seedling is often weak and stunted and should be discarded. The other seedlings are clones of the mother tree."
Has the mother tree produced well? Any chance you could post some pics--mother and especially babies? Thanks.
