Effect of Initial Root Collar Diameter on Survival and Growth of Yellow-Poplar Seedlings Over 17 Years

A nursery study was installed to test the effects of seedbed density and top-pruning on field performance of bareroot yellow poplar (Liriodendron tulipifera L.) seedlings. Seedlings were grown at a density of either 9.5 or 16.3 seedlings/ft2 (102 or 175/m2 ) and half were top-pruned in August to a height of about 10 inches (25 em). Outplanted seedlings were measured for heights at ages 2, 9, and 17 years. Survival and growth were positively related to initial root collar diameter. Neither top-pruning nor seedbed density had a lasting effect on growth. Tree Planters' Notes 47(1):30-33; 1996.
