Degeneration and Regression Processes in Carpinus betulus Forests of Trentino (North Italy)

The study presents recent data on the distribution of Fellhanera gyrophorica (Pilocarpaceae, Ascomycota) in Poland, a rare lichen with a crustose, usually sterile thallus. Both previous and new localities of the species are presented with data on its ecology and general distribution. Furthermore, this paper provides detailed results on floristic investigations of the species in the forest areas of the Pojezierze Olsztyńskie Lakeland (Northern Poland). Fertile specimens of F. gyrophorica have been observed in Poland for the second time and in the world – for the third time. Also, a new substrate for this species has been found: Acer platanoides. In addition, Carpinus betulus and Populus tremula were also found to be the species' substrates in Poland. Based on this study and previous reports, F. gyrophorica seems to be a relatively common species in north-eastern Poland.

Uncertainty among Greek farmers who are in search of new and profitable crops has increased interest in truffle cultivation. Recent research has come up with 23 taxa of hypogeous fungi new for Greece including gastronomically valuable species. Natural ecosystems of Quercus pubescens, Q. frainetto, Q. ilex and Q. coccifera seem to be rich in hypogeous species. Ecosystems with Corylus avellana, Carpinus betulus, Mediterranean pines and even poplar plantations were found to also host hypogeous fungi. These records, supported by historical information about the existence of truffles in Greece, seem to be encouraging hints for systematic truffle cultivation.

Phytotoxic Activity

The results of the study of phytotoxic effects of water extracts from Pinus sylvestris L., Betula pendula Roth, Quercus robur L., Picea abies (L.) Karst. P. excelsa Link, Carpinus betulus L., Robinia pseudoacacia L., Populus tremula L., Crataegus submollis L. are presented. For а comparison of the phytotoxic activity of the investigated plants was used to measure the change in the intensity of the mitotic division, depending on the concentration of aqueous extraction of plant material (tangent trend curve of cytostatic activity). According to this parameter, the following row of phytotoxic activity of wood species can be ordered: Populus tremula, Betula pendula, Robinia pseudoacacia, Carpinus betulus, Acer platanoides, Tilia cordata, Pinus sylvestris. Water extract Quercus robur and Picea abies have discovered a phyto-stimulating effect. The results of the study allow us to discuss the possibility of introducing the parameter of the phytotoxicity coefficient to determine the allelopathic effect in the tree-tree system.
