cutting onco seeds - forced germination
penstemon (Sat, 15 Nov 2014 15:59:12 PST)

rotten seeds. I have cut hundreds of seeds, and as pictured in my pictures
on the thread on the Scottish Rock, the hillum end of the seed needs to be
cut for forced germination, as I was taught it, to work.

Oh great. So I did this backwards. It wouldn’t be the first time. The seeds
still do germinate, though.
But, yes, if the aril is removed, the embryo is quite visible. I did find
some rotten seeds in the bunch; brown, obviously-dead embryos.
