inducing tetraploidy

 

This topic has been discussed over the years, but I never paid much attention because I knew I was never going to mess with chemicals like colchicine at home.  Lately I keep hearing of less dangerous methods, and I'm planting seeds now, so I thought I'd bring up the issue again.

How can I convert my iris seedlings to tetraploid?  I dream of crossing things like tetraploid Iris tridentata with tetraploid Iris fulva.  I played the waiting game and nobody created tetraploids for me :-) so I guess I better do it myself.  Or find a lab that can do it for me?  Or maybe SIGNA could sponsor some research students to do it in a proper lab?  I dunno....

Google searching is a bit overwhelming.  But there seems to be a buzz about less harmful chemicals such as Oryzalin.  But I still get the heebie jeebies about using mutagenic chemicals in my home.  :-/

I know a daylily breeder nearby... maybe I could hire him to convert some of my seeds.  I also know a grad student at OSU... I'll bug him too.
