This work reviews mass production of the aboveground biomass and energy content of 39-yr stands of Quercus rubra L. and Juglans nigra L. on a PRA at Ivanka near Nitra. The maximum stock of the aboveground dendromass of the saids stands of 233.76 t per ha with an energy value of 4556.83 GJ per ha was determined on PRA VI (Juglans nigra L. 20%, Quercus rubra L. 80%) and the minimum stock of 180.91 t per ha with an energy value of 3497.87 GJ per ha on PRA V (Juglans nigra L. 20%, Tilia cordata Mill. 80%). The observation of energy value in individual parts and components of the above dendromass of the stands of Quercus rubra L. and Juglans nigra L. showed that the greatest energy content of 21 352 J per g is cumulated in leaves of Quercus rubra L. and the smallest of 18 583 J per g in bark of 1-yr twigs of Juglans nigra L.
