The largest leaf area was found in a mixed stand of chestnut with sessile oak Quercus petraea (5.89 ha.ha-1), the lowest in a mixed stand of chestnut (2.09 ha.ha-1). Highest aboveground biomass was in the mixed chestnut stand with sessile oak (62.05 t.ha-1). In this type of stand the highest mean year dry matter production of the aboveground biomass per unit of stand area was 4.72 t.ha-1.yr-1. The highest mean year dry matter production of the aboveground biomass per leaf area unit was found in the chestnut mixed stand with lime Tilia (1.81 g.dm-2.yr-1).
