Notes: Response of an Eastern White Pine Provenance Test to Pruning
A 14-seed lot, rangewide provenance test of eastern white pine, established in southern Michigan in 1960, was pruned at intervals of 1-3 years from 1965 to 1975, 1-2 whorls being removed each time. Ten trees per seed lot were cut in January 1977 and the pruned nodes were sectioned and measured for amount or date of wound closure. With 6- to 10-mm diameter growth per year and the largest branches varying from 17 to 23 mm, 4-8 years were required for complete wound closure. Seed lots varied significantly in rate of closure, those with rapid growth and/or small branches healing most quickly. Genetically, rate of wound closure plays a less important role than growth rate in determining the amount of clear lumber produced during a rotation of reasonable length. Forest Sci. 26:606-608.
