摘要：The paper presents the results of a study on the regime of light and regeneration in a pure sessile oak stand in ' Fruşka Gora' National Park in Serbia. Pure sessile oak stands cover 3960.73 ha or 17.6% of the area. The study stand is ecologically classified as the forest of sessile oak with fescue (Festuco drymeiae - Quercetum petraeae Jank. 1974) on acid brown andillimerised soil over sandstone. The 96 year-old stand is even-aged and vegetative. It is located on east and west facing slopes at an altitude of 450 m, with the slope inclination of 320. The starting hy- pothesis of this paper was that light regime has sig-nificant effects on the success of sessile oak forest regeneration. Data collection was performed in earlyJuly 2008. The study of regeneration elements (seed- ling number, height and quality) was conducted at the end of the growing season at the seedling age of 3. Light conditions that are most favorable for regen- eration include the intensity of illuminance between 5000 Lx and 10000 Lx, i.e. 11.3% to 22.6% ofull daylight. The number of seedlings and their spatial distribution on the regeneration plot are in these spe- cific site and stand conditions affected by the light regime of the area, making light most decisive, but not the only factor affecting their spatial distribution.
