Chemically induced poly/tetraploidy

[dr. dugmore]

Havent been on here in AGES!
I'll tell you what I've been up too in the general forum, but for now, I have a question on Tetraploidy.

My gran grows heaps of flowers, I'm looking for an experiment to conduct, before i finalise somthing, I have a few asks:

I just need to know if there are any chemicals that can induce the mutation, and the process on how to go about it? I really have a limited idea about it, but aparantly some flowering plants can be induced somehow by a substance called colchine?

Let me know if i'm making no sence whatsoever, I'm just getting some thoughts out, and its rather late.

Colchicine: http://en.wikipedia.org/wiki/Colchicine
I do not have a protocol to induce mutation, but maybe a search with the right name might prove helpful. The second problem is do you have access to a lab that is allowed to handle that? Usually poisons are not easily found in the supermarket.
