The various iris seed are well programmed for survival of the  species.  
Unfortunately, that programming works contrary to the needs of  the hybridizers.  
 
Breaking dormancy:  As seed germinate they release a chemical.  I  can't 
remember what it's called.  I thought it was the same compound as  released by an 
apple, but research shows that the apple releases ethylene, which  doesn't 
sound right.  I'm thinking anasomething or other?   I'm  going on a memory that 
is over 30 years old. 
 
Years ago I read that seed planted in a clump (not just iris seed) would  
germinate better.  The released chemical was thought to have a  ripening effect 
on the rest of the seed.   
 
Is this an Urban Legend?  At some point, I was told this is not  true.  
Anyone able to clarify this for me?
