Loblolly and slash pine rooted cutting research at N.C. State University

Through the efforts of several N.C. State University scientists and with support of nine forest product companies, a loblolly and slash pine rooted cutting research project was initiated in January of 1992. Focus of the research is on: (l) genetic selection (culling) for rooting ability, (2) physiological process research on the fundamental mechanisms for adventitious root initiation, (3) stock plant or hedge physiology and culture with emphasis on carbohydrate / nitrogen ratios in the stem cuttings produced, (4) rooting environment research, and (5) investigation of auxin treatments for stimulating rooting and their effect on root system quality.
