Just to be clear, my seedling is Hippeastrum X Nerine. And until it
blooms, I can only hope it is indeed the targeted cross and not some freak
parthenogenesis....
I think embryo rescue makes a lot of plants more orchid-like in their
intercompatibility because so many intergenerics yield viable embryos but
the mother plant doesn't recognize them and make some endosperm. Orchid
seed culture was devised to get around the fact that orchid seeds never
have any real endosperm. So doing the same treatment on
endosperm-defective seeds of other kinds of plants was a natural thing to
try and it has been demonstrated many times. Tubes of sterile medium are
about $3 a pop in quantity, and a small sterile workstation can be had for
around $250. So for the price of a few decent bottles of scotch anyone can
get in the game!
