Re: Iris seeds germinating

 

I'm not speaking from experience, but, yes, that's one of the reasons to do embryo culture. It seems that malformation of the endosperm is one of things that reduces viability of wide crosses.

I produced almost no seed this year due to the crazy spring weather that destroyed most of the state's orchard crop. However, I did get three undersized seeds on a wide tectorum cross. Opening one up, it seemed to have a normal embryo but no endosperm. This is exactly the sort of thing tissue culture is good for, right?

Hi Walter,

Thanks for the pointer to the "home tissue culture group"! I've done some embryo culture with Aril species and Arilbreds with pointers from Jim & Barbara Whitely and hope to do some more experimentation. I reduced contamination problems, in part, by mopping the kitchen (laboratory) floor with a weak bleach solution and running a hepa air filter. I'm looking forward to learning more from the group.
