Biomass Characteristics Of Sycamore Coppice Influenced By Parentage And Type Of Planting Stock
Three years after clearcutting a six-year-old sycamore progeny test in northeast Mississippi, stem dry weight of coppice averaged 2.27 Mg/ha and represented 63% of the above-stump dry biomass. Stumps of trees established from unrooted cuttings produced fewer coppice sprouts, smaller sprouts, and 40% less coppice stem dry weight than stumps of trees established from seedlings. There were no differences between stumps originating from top-pruned and unpruned seedlings. Progeny families differed in survival, dry weight yield of five-year-old trees before the clearcut, and number and maximum diameter of coppice sprouts per stump. Small, positive correlations between stump diameter before clearcutting and the resulting coppice characteristics were found, and these relationships may differ among families.
