Auxin Induced adventitious root formation

We have just completed an experiment in an intro biology class trying
to induce adventitious root formation in bean plants. The data seem to
show quite nicely that IAA inhibits adventitous rooting.  Going back
and rechecking my books I seems that this is not supposed to be so.

My guess is that we are seeing some sort of competative inhibition of
auxin function by breakdown products of the old IAA we are using. Does
that make sense? Are there any other  likey explainations? 
Thanks for your help,
Ethan Strauss?
