Carbohydrate dynamics in roots, stems, and branches after maintenance pruning in two common urban tree species of North America
The ability of plants to tolerate stress is determined in part by the carbon allocated to their reserves. We studied two common urban tree species in northeastern North America, Acer saccharinum (Silver maple, native) and Acer platanoides (Norway maple, exotic), to assess the dynamics of non-structu...
