Re: HYB: seed germination?

 Griff Crump  --  along the tidal Potomac in Virginia-- said:
< I got two pods on it [Brazilian Holiday] in 2000; one gave 55 seeds,
of which none  germinated; the other gave two seeds, of which one
germinated.  Both  were crosses with seedlings.  To be fair, I must say
that I had  generally lousy germination in 2000.  I'm looking to see
what the  sole survivor turns out to be this spring.>

Wonderful to hear, Griff (misery loves company).  Do you have theories
about why you had such poor germination (about the same miserable
success I've had the last two years)?

Weather, nutrients, other environmental factors during seed development?

Ditto during seed germination?

Genetics of the mixture of parents?

All of the above?

Strange things I haven't thought of that happen on the west coast that
we don't have?  Mycorhizal interactions within the womb? [don't panic,
BS, I'm being silly, but you never know....]

Did your seeds look 'normal'?  All of mine did, and like your BH pod,
some of my pods had a lot of seeds.

I wonder if average number of seeds set per pod combined with number of
successful pods per cross under presumably good conditions to make
crosses (right age of bloom, humidity, temperature, nutrition etc) might
give some indication of viability of seeds?  In other words, the last
three years, I had a poor success rate in setting pods and a poor
germination rate the last two springs, plus it is looking like another
dismal germination rate this year.  At least this year, I will be pretty
certain it isn't due to conditions during germination, since I've gone
pretty much with as much control as I can muster..

I'd appreciate any thoughts from hybridizers who sometimes have poor
germination and sometimes good.
