Effects of Eight Nursery Treatments on Yellow-Poplar Seedling Characteristics and Field Performance

Because yellow-poplar (Liriodendron tulipifera L.) is the hardwood species most commonly planted in the Southeast, it is important to know which seedling characteristics are desirable for success in planting. Yellow-poplar seedlings have been graded by root-collar diameter (2). Root length, seedling height, shoot-root ratios, and other characteristics have had less effect on survival (1). Seedling quality varies by mother tree and seedbed density (3). Although root-pruned seedlings usually have more fibrous root systems than unpruned seedlings (3), little is known how root-pruning, top-pruning, and fertilization of seedlings affects survival and growth in plantations.
