Can Lagerstroemia indica be grafted with Rhododendron?

The key to the survival of different kinds of plants is the affinity between rootstocks and scions. The order of grafting affinity of plants from strong to weak is the same genus > different genera > different genera in the same family, but if the same family is different from each other, the affinity is zero and the grafting cannot survive.

In botanical classification, Lagerstroemia belongs to dicotyledonous plants, Ulmaceae, Myrtaceae, Lagerstroemia, Rhododendron belongs to dicotyledonous plants, Ulmaceae, Ericaceae and Ericaceae. It can be seen that the two are not only different families, but even begin to "go their separate ways" at the level of subclasses, and it is impossible to survive by grafting.
