I actually did my doctoral research investigating, among other
things, the effect of mycorrhizal inoculation on blueberries, then
went on to look at mycorrhiza on apples. Briefly, what I found is
that under field and nonsterile conditions, mycorrhizal infection is
ubiquitous and the effect of deliberate inoculation is
inconsequential. Sometimes it's even hard to prevent infection even
with sterile soil under greenhouse conditions. Other research,
however, has occasionally shown benefit of inoculations to young
plants before they are field-planted. (See, for example, work by Dr.
Doud, with the USDA). At any rate, I don't imagine that mycorrhiza
would have a specific effect on grafts beyond their effect on plant
