[nafex] no new growth on young apple?

I was hoping to get some new growth on this apple tree this spring, so I could use it as grafting stock. But every twig ends in a rosette, like the ones shown below, with nothing sprouting. Is there anything I can do? Would it help to cut the rosette off? Would it have helped if I did it earlier in the season? Anything else I could do to promote new growth?

It's an Ashmeads Kernel on G205, I think. It's in a lousy spot, and won't ever get enough sun. (Thus my interest in grafting it to something else, somewhere else.)

Thanks for any advice,
