Abstract

    Researchers sought to determine the impact of commercial thinning practices on defoliation recovery by examining the ability of red spruce and balsam fir to recover from defoliation by storing non-structural carbohydrates (NSC's) used for foliar growth and secondary defensive compounds such as lignins and tannins.
