Well, actually, it was kind of a goofy idea. Once again, I spoke before
thinking through something.
In tissue culture, one 'generation' is a 'cloned' plant that is
developed from a few (?)cells of the 'parent' plant. Big difference
from a 'cloned' plant from a 'parent' iris mother rhizome, which
hopefully 'knows' how to make these clonal offspring without making too
many mistakes in the 'programming'. As I recall (after I spoke meself
too quickly), the 'errors' in cloning new 'generations' were thought to
be at least partly, or mostly due to technique (growth media and
physical environment).
Sharon, Bill, I hope you are going to step in and help me get my big
foot out of my mouth.
