Re: HYB: growth problems- epigenetic inheritance

All the articles I've found online so far require subscriptions, darn it all. Some of the titles sound like the research deals specifically with multigenerational changes in seedlings.

I'm not sure if it works that way or not - all that's 'for sure' is that there <might> be a <different> effect on seeds set and matured in a wet spring vs a dry one, but maybe not.

It seems like it would depend on whether there were enzymes strongly affected by 'too much' wetness vs 'not enough'.

In other words, just because the parents are affected by the weather doesn't <necessarily> mean the babies would be. And it might depend on the parents' genetic makeup (some might be more likely to be able to make changes than others).

But if they <are> affected, then yes, from what I understand.

Have you seen anything to indicate it might be true?

It made me think of the IMM X CSONG cross - the first time I made the cross, there were around 50 surviving seedlings, some good ones, 2 rebloomers, several colors, mostly short. The second time I made the cross, there were fewer seeds to start with, about a dozen survivors, higher percentage of tall ones.

Makes me want to do more experiments - as if I weren't already over-run with seeds and seedlings.

So?? Seedlings set and matured during a wet spring should be more tolerant of wet conditions and vice versa? To produce irises that will live well under any given set of conditions, the parents should be growing in those conditions when the cross is made? Betty>
