Rooting hormone to improve grafts?

This study indicating that rooting hormone may improve grafting success intrigued me. Has anyone here experimented with it? It might help me with my difficult-to-graft nut trees, and improve the vigor of any grafts.

marc,
It was discussed on some of the nutgrowers lists a number of years ago. I never got around to trying it, but might give it a shot this year - though my successes with pecan/hickory/walnut have regularly been so hit or miss, I can never really figure out why one graft took and another didn't.

I always dip my tree cuttings in rooting hormone. I don't know if it actually helps, but I figure it can't hurt.

I do not think at all that I am beyond 'first grade level' in my grafting progress, with only a few hundred grafts. I frequently will let prepared scions stand in a cup with a couple inches of water enhanced with a few drops of Super Thrive for a few hours or even a full day prior to grafting. I want the sticks to be hydrated and nourished additionally before being abandoned on top of a branch that will not nourish it for a while. I let the waterlogged lower area air dry to a 'normal' amount of moisture before actually doing the graft......When the word Super Thrive is typed, I know...,the hair on back of some necks begins to rise....As in Dr. Ignaz Gemmelweis.
