Pinetum pleuroziosum - Opis:
- Geobotanical studies of the resource lingonberry Vaccinium vitis-idaea L. of different-aged communities of the pine forest with mosses on the territory of the nature reserve “Grodnenskaya Pushcha” (Belarus) have been carried out. A linear relationship was found between the yield of V. vitis-idaea shoots (air-dry weight) and the projective cover r = 0,85; productivity (g/m 2) = –3,03253 + 1,79386* projective cover (%), (r 2 = 0,73)). The mode of illumination, moisture, and soil acidity affects the resource-cenotic parameters of V. vitis-idaea quite strongly (η 2 ± mn 2 = 51,3 ± 8,3 – 99,8 ± 0,1%). However, the linear dependence of the parameters on the factors was either not revealed or low (up to r = 0,38). This indicates a non-linear relationship (k > 4,0) of the studied parameters of V. vitis-idaea with abiotic environmental factors, which is formed under conditions of interspecific competition and ecological mosaicism of phytocoenoses. A positive relationship was recorded at low values of the projective cover between the blueberry V. myrtillus L. (up to 20%) and V. vitis-idaea (up to 5%), which indicates a positive relationship of these species in the phytocoenosis with their low abundance.
