Two-year-old, bareroot, Corylus colurna seedlings were grown in 7.5-L containers from 15 Mar. to 23 June 1995. Plants were grown in a glasshouse using pine bark media. Temperatures were maintained at 30/20°C. Plants received no fertilization or Osmocote 18–6–12 top-dressed at 14 or 28 g/container. Additionally, plants were pruned to remove 0%, 25%, or 50% of the root system based on root length. Height, diameter, branch number, leaf area, and root and shoot dry weight increased linearly as rate of fertilization increased. Percent embolism was not influenced by rate of fertilization. Plant height, branch number, leaf area, and root and shoot dry weight were not influenced by rate of root pruning. Plant diameter increased linearly as rate of root pruning decreased. Percent embolism increased linearly as rate of root pruning increased.
