o:8836 Microclimatic characteristics and regeneration of sessile oak in the Fruška Gora National Park, Serbia en Abstract: The paper presents data on microclimatic conditions (air temperature, soil temperature, relative humidity, solar radiation, wind direction, and speed) in a pure stand of sessile oak within Fruška Gora National Park. The phytocoenological affiliation of the stand is a monodominant sessile oak forest (Quercetum montanum typicum Čer. et Jov. 1953). The stand is even-aged, of vegetative origin, and 101 years old. It is located on a northwestern exposure at an altitude of 470 m, with a 6° incline and a canopy cover of 0.6. The results of the microclimate research conducted in July 2008 showed that the average air temperature during this period ranged from 19.2°C to 28.9°C, peaking at 2 PM. The relative air humidity varied between 34.2% and 54.2%, while solar radiation levels ranged from 7.5 W/m² to 675.0 W/m². The average daily value of the soil temperature ranged from 18.8°C to 21.7°C, with a culmination two hours after the culmination of the air temperature. The data were compared with the reference climatological station Rimski Šančevi located near the object of the study. The most frequent wind during the research period was from the south to southeast direction with an average speed of 0.7 m/s. These microclimate data are crucial for the success of forest regeneration, as they allow three-year-old seedlings to survive and develop successfully. The number of individuals per hectare is 38 pcs/m2, i.e., 380,000 individuals per ha. Understanding these conditions is also crucial for establishing new forests through seed sowing. 1552100 978-99976-070-4-1 2025-12-24T12:30:32.430Z 44 yes 46 Violeta Babić 0000-0001-6848-8442 46 Zoran Govedar 0000-0001-9791-4113 46 Marina Vukin 0009-0007-4664-4089 46 Snežana Stajić 0000-0001-9023-3542 46 Branko Kanjevac 0000-0002-5940-3600 46 Branka Pavlović 0000-0002-7507-2231 46 Bojan Konatar 0009-0006-9023-4397 application/pdf 1699073 https://unilib.phaidrabg.rs/o:8836 no yes 1 70 92000004 71A07 "Book of Abtracts - XVI International Scientific Agriculture Symposium “AGROSYM 2025”" 635 635 Faculty of Agriculture, University of East Sarajevo, Republic of Srpska, Bosnia and Herzegovina 2025
