Abstract

Oaks have a bad reputation as subjects for grafting due in part to reasons of immediate or delayed graft incompatibility. This paper describes grafting section Cyclobalanopsis oaks, which pose additional problems due to their lack of tyloses and the fact that they are evergreen. The author discusses the possibility of using a mutually compatible inter-stem for grafting oaks using a double-working technique, as has been done for decades with fruit trees.

Keywords

side veneer graft, mutually compatible inter-stem, double working, warm callusing, enclosed environment
