I have not had any experience yet on this but I have a batch of
colchicine standing by for when I want to experiment. The stuff is
highly toxic so I am wary of experimenting.
Colchicine works by inhibiting cell division after chromosomes have
duplicated. However, the resulting tetraploid cell may not be stable.
Seed treated with colchicine has less than 10% survival rate.
Currier McEwen who pioneered tetraploid Siberians now has Parkinson's
disease from his extensive use of colchicine. I want to emphasize that
this is a high risk procedure and that anyone who is considering this
should take all safety precautions.

Hi.
I read the article in the bulletin about the conversion
of diploid
irises into tetraploids for hybridizing purposes. I was
wondering if
anyone on the list had any experience with this?
Also, does anyone know a good source for Raspberry
Ribbon and Sindjka
(?) If YOU have some, I would be willing to trade
Pinnacle (a historic
for a historic...there's an idea!)
Rusty...whose ears will once again be "tubular" on
Friday.
