Grafting Slash Pine in the Field and in the Greenhouse
This experiment was designed to develop a suitable grafting technique for slash pine (Pinus elliottii Engelm.) as part of the forest genetics program. The techniques developed will be used in future breeding work to estimate the genotype of selected "plus" trees, to propagate selected trees and to establish seed orchards from superior parent stock. Various types and modifications of standard horticultural grafting methods have been tried with conifer forest species. It appears that special techniques have to be developed for the various species occurring in different climatic regions. A method which is successful in one climatic area may prove a complete failure in a region having different weather conditions. Such factors as time of grafting, age of stock, type of graft, and environment are extremely important if a large number of successful grafts are to be obtained. This study seeks to answer two questions. Is it physiologically feasible to graft slash pine scions? And which techniques are most efficient under north Florida conditions?
