Again, as I understand it, incompatibility "kicks in" only after the embryo germinates, when it tries to use the incompatible endosperm. Therefore, I would think the best time is when the embryo is mature as possible, but still able to be separated from the endosperm. I read somewhere how the embryo "pops" out when squeezed correctly. I guess I just assumed it was with nimble fingers, but..... So I would assume the seed must still be very turgid. I don't think anything would "pop" out in a half turgid seed. Sounds like it would require a lot of practice. And not only that, different types of lily seed can have different embryo placement within the seed, complicating things even more.
I hope I'm making sense here. I guess I'm behind the times (hardly ever watch TV), but I just "discovered" 2Cellos and am listening to them as I write. (I'm three-quarter Slovenian, and one of the guys was born in Slovenia.) So this music is new to my analytic mind, and I can kinda almost understand their Croatian, too.
