Results of light regime research in pure sessile oak stands located in the area of National Park Fruška Gora, are shown in this paper. Pure sessile oak stands in this area cover 3960.73 ha, i.e. 17.6%. Researched stands belong to the most frequent sessile oak type (Quercetum montanum typicum Čer. et Jov. 1953) on acidic brown soils and limerised acidic brown soils. Stands are even aged, origin is vegetative, between 100 and 105 years of age. Data collecting was done in the summer of 2008, on two different aspects. The stand on southeastern aspect is located at 350 m a.s.l., inclination is 15 degrees, canopy is sparse (0.5 to 0.6). The Stationary isohel method is used for the ascertaining of stands light regime. Isohel maps were drawn the average light intensity and light permeability indices were calculated for the areas between isohels, based on average light intensity values on monitoring spots. Significant differences in light regime established in researched stands which have different canopy and aspects.
