Abstract
In Lithuania Hypericum maculatum Crantz. is the second widely spread species of Hypericum L. genera. This species has a tendency to produce big amounts of essential oils and flavonoids which might be of wide application in pharmacology. There is a relationship between some environmental conditions and the essential oil composition due to both biotic and abiotic stresses which have the impact for the formation of secondary metabolites. Present study is aimed at evaluation of environment of H. maculatum according to associated plant species. In Lithuania, eight different sites with H. maculatum were selected and neighbouring herbaceous plants were recorded and the abundance of each species was evaluated. Abiotic environment characteristics were obtained using Ellenberg’s indicator values (EIV) of the neighbouring species. According to Ellenberg’s indicator values of plants in Central Europe environmental indexes for H.maculatum were: 8 for light, 3 for continentality, 6 for soil moisture, 3 for soil reaction and 2 for soil nitrogen, the species were indifferent for the temperature. For populations growing in Lithuania climate is colder and more humid compared to Germany. For eight selected sites 133 plant species as 28 family representatives were registered. In most cases species coverage data allowed to group sites according to their habitats. Abiotic environment EIV of H. maculatum sites characterized by the Ellenberg’s indicator values of associated plant species ranged rather wide: 6.21–7.14 EIV for the light light, 5.36–5.80 EIV for the temperature, 4.93–6.13 EIV for the soil moisture, 5.54–6.86 EIV for the soil reaction and 2.71–5.21 EIV for the soil nitrogen. The biggest differences in the EIV between populations were for soil properties like soil nitrogen (1.92 times), soil moisture (1.24 times) and soil reaction (1.24 times) and the minimum difference between population were for climate properties.
