Hi Brian,

Sounds like an interesting project.  We use colchicine all the time to
disrupt microtubules and look at their role in vesicular trafficking of ion
channels in my lab, but I never before looked into it in terms of plants.
After reading your post and then a few articles I guess I'd say what the
heck, it's so easy why not give it a whirl.  Obviously, all you'd need is
enough seed/plant material to try many concentrations and various time
points.  I would caution that if you don't know what your doing with toxins
like this it wouldn't be a wise choice.  Hopefully you have a good
analytical balance and a hood for working with these types of compounds.  If
you're planning on using DMSO as a carrier I'd hope you would double
glove....better safe than sorry.  Perhaps this would be a fun project for
next spring in the lab.  It will be interesting to see what others familiar
with plant cell biology have to say!
