Rootstock mass of coppiced Platanus occidentalis as affected by spacing and rotation length
The root mass per unit land area for Platanus occidentalis was determined 9 years after planting 1-0 seedlings. Trees had been planted at 0.3 X 1.2, 0.6 X 1.2 and 1.2 X 1.2 m spacings and coppiced after two growing seasons in the field. Rotations of 1, 2, and 7 years were then imposed. Rootstocks coppiced annually had significantly less rootstock mass (16.0 tons/ha) than those harvested on longer cycles. No significant difference was found between the 2- and 7-year rotations, which averaged 22.8 and 25.2 tons of dry rootstock mass per hectare, respectively. Spacing did not affect rootstock mass per unit land area. Rotations of 2 years or longer and relatively wide spacings are recommended for short rotation forestry.
