Grafted maples?

[IowaTap]

I've got ~20 taps in my backyard and am planning for the next generation of trees (should be ready to tap by the time I retire!). I saw potted sugar maples (~1-1.5") on clearance at Lowes so I bought a few. But when I got them home and took the wrap off the trunk, it looks like they've been grafted. Anyone know why they'd do that or have any experience with grafted maples? My plan is to rig a mini-tap next season to see what % they produce and go from there.

I bought 40 at Walmart this spring and they were all grafted. Makes me wonder if I can graft rock maple onto something with an established root base and kick start a acer sacrum into growing faster

The University of Vermont did a study with grafting sugar maples onto Sycamore maple rootstock (they can survive in higher salt environments than sugar maples) to determine if a sugar maple could be grown that is salt tolerant. The experiment was successful.
I wonder if the root stock on the grafted sugar maples was sycamore maple, a maple that does well in areas where road salts and sidewalk salts would kill a sugarmaple on it's natural roots.

Interesting if a sugar maple was grafted onto a popular root stock would it still be a sugar maple

Maplemaniac, it is my understanding that to graft the trees have to be a similar type of tree, so whatever you grafted would have to be a maple variety also.

I have never grafted before

I've grafted but only on fruit trees.

I do a lot of fruit grafts never maple. If you use maple root stock, red, silver, norway etc, I think it would take well. Never tried as we have plenty of all ages in my bush. I might try some for kicks next spring.
