First, Colchicine is a very toxic substance -- be extremely careful 
using it.

You need to treat the seeds, not the plant. Make a weak (1%) solution. 
treat LOTS of seeds. Soak and let dry two or three times then plant.

If you get good germination, the treatment did not take. It should kill 
about 95% of the treated seeds. 1% of the 5% left MAY mutate.

Colchicine is used in orchid propagation, seeking tetraploid plants with 
large flowers and heavy substance. A VERY SMALL AMOUNT WILL KILL AN 
ADULT. REPEAT: A SMALL GRAIN of this stuff will kill you. If it gets in 
your food, on your fingernail, anywhere - in your eye, if you breath the 
dust, etc. It will kill you. Be careful. It is also a very powerful 
carcinogin.
