Some aspects of site conditions of heathlands in the Torun Basin

The aim of the paper is to characterize some aspects of site conditions in selected places with the occurrence of heather (Calluna vulgaris) within the certain area of the Toruń Basin affected by military activities. Relations of heathlands to the soil cover appear to focus on the position of heather in the ecological succession on presently developing, young sandy soils and regularities of the heather distribution in a mosaic with grasslands in isolated dune fields. Studies were performed at two sites: Stawki and Chorągiewka.Heathlands of this area are connected with nutrient-poor and dry sandy habitats. In the ecological succession, which proceeds in places previously devoid of the vegetation cover and strongly deflated, they occur as a transitional type of vegetation, displacing plants of initial psammophilous community (Spergulo-Corynephoretum) and later giving place to pine forest. In the soil evolution, they are connected with the intermediate stage represented by arenosols (haplic arenosols) - weakly developed but sufficiently acid soils. On deforested, parallel dunes of the Toruń Valley, there are specific regular mosaics of vegetation and soil. Heather occurs on podzolized soils (albic arenosols, haplic podzols) on north-western slopes. Dry grasslands (Calamagrostis epigejos) cover slopes with south-eastern exposition, with soils eroded down to bed-rock and now regenerating to the stage of arenosols (haplic arenosols). Podzolized soils seem not to be developed under heather but rather under the relics of former pine forests preserved from erosion and deflation on less steep and more moist slopes.

This paper presents the results of comparative studies on seed morphology and anatomy of two species: Erica carnea and E. erigena. SEM and LM micrographs are presented. The seeds differ in size and shape of epidermal cells of the seed coat, but they represent the same structural type, which is clearly dissimilar from that of the other European species of this genus.

The aim of the study was to determine the fungi causing dying out of one-year- old heather seedlings. Observations were carried out on: 'Amethyst', 'Annemarie', Colette’, 'Perestroika' and 'Reini'. The shoots revealing necrotic symptoms were plated on PDA medium. 25 species of fungi were isolated. Among them Pestalotia sydowiana, Alternaria alternata, Cylindrocarpon destructans, Leptosphaeria coniothyrium and Epicoccum purpurascens were dominant, while Mammaria echinobotryoides, Phoma leveillei, Kaissleriella subalpina, Botrytis cinerea and Phytophthora cinnamomi occurred less frequently.

Thirty two samples of different types of Polish honeys were investigated in order to assess their total phenolic content by Folin-Ciocalteau method and their potential antioxidant activity by 1,1 diphenyl-2-picrylhydrazyl (DPPH) and ABTS methods. Results of the study showed that the total phenolic content and antioxidant activity differed widely among different honey types. The highest phenolic content and antioxidant activity had dark honeys, while the lowest antioxidant activity and phenolic content were found in pale honeys. Statistical analysis showed that the total phenolic content of honey was correlated with its antioxidant activity.
