In Proceedings of the 25th Biennial Southern Forest Tree Improvement Conference: 1999 July 11–14; New Orleans, LA. New Orleans, LA: Southern Forest Tree Improvement Committee; 2000: in press. This study is the first report of induction of somatic embryogenesis from tissues (apical meristems) of mature pine trees, and provides an excellent example of the economics of applying such an approach for selectively propagating mature trees based on their individual fiber properties.
