Abstract
Cleft grafting ponderosa pine proved best of five methods of vegetative propagation tested for field use in the dry hot climate of eastern Oregon. Ponderosa pine has been successfully grafted under many conditions elsewhere, but first trials in this area during 1955 were a failure. This study was made in 1956 at the U.S. Forest Service nursery at Bend, Oreg., to find a field method suitable for propagation of plus-tree stock.
