Opis:
Grey alder (Alnus incana Moench.) in Poland is a recommended species for dry and oligotrophic habitat improvement and land reclamation. In Poland these issues have not been thoroughly investigated. The field experiment with Scots pine and grey alder in the mixed plantation was carried out on the fire−burnt area in the Potrzebowice Forest District. The proportion of grey alder in the species composition of plantations notably improved the growth of pine, but only with a 50−75% share of alder. This created some disturbances in the tending of plantations. The impact of pine on alder was negative.

Opis:
Scots pine (Pinus sylvestris L.) seedlings which were inoculated with ectomycorrhizal fungus – Thelephora terrestris and grown in different regimes of N fertilization [Hilszczanska, Sierota 2006], next year were planted out on post−agricultural land. The development of fine roots after 6 months of vegetation, number of mycorrhizas, identity of some mycorrhizas and growth parameters of Scots pine seedlings were studied. Mycorrhizal abundance was higher in the inoculated previously variants than in non−inoculated ones. PCR RFLP analysis confirmed share of two different isolates of Thelephora engaged in mycorrhizal symbiosis. Growth parameters was higher in non−inoculated seedlings. Vitality of seedlings was lower at lower level of N fertilization in non−inoculated treatment.

Opis:
The research was conducted on the external spoil heap of the 'Piaseczno' Sulphur Mine (southern Poland). This paper aimed to determine the quality of wood in 40−year−old Scots pine trees planted onto the external spoil heap of the mine, in the scope of forest reclamation, depending on the soil substrate and employed reclamation treatments. The investigations were carried out at one−are circular trial plots. A total number of 17 study plots was established, located on: Quaternary loose sands (PL), mixed Quaternary sands and Tertiary Krakowieckie clays (PI), and mixed Quaternary sands and Tertiary clays after an intense initial fertilisation (PIN). Measurements performed at the study plots included determination of diameter at breast height of every tree with a diameter ≥7 cm and height of every tree. We classified the wood of standing trees, including a specification of class or quality and dimension group of the butt−end part of the trunk, identifying types and variants of defects that determined the results of quality classification of raw wood. We found significant differences in trees dimensions between soil substrates. No significant difference was found for fertilised substrates, therefore it may be assumed that fertilising of more fertile soils was an unnecessary treatment. The quality of pine wood was mostly affected by knots and curvatures. An impact of knots on the results of wood classification increased with fertility of soil substrate. With regard to curvatures, the opposite trend was recorded. The frequency of occurrence of the above−mentioned defects was determined not only by the habitat type, but also by the manner of forest management. To reduce the frequency of occurrence of the defects in question in the reclaimed areas, an appropriate closure of stands should be maintained and adequate tending treatments should be performed competently and skilfully, as this is done in commercial stands.

Opis:
Tree−ring analysis of pine stands living under the influence of industry in south−eastern part of Silesia−Krakow Upland was performed for the last years. Now the new transect was added in the Olkusz region. Previous studies showed the distinct relationship between number of trees with observed reductions and distance from main source of pollution it this region. On the sites localised nearest to zinc−works "Bolesław" the value and the duration of reduction periods were the biggest. On the sites of new transect (OL VI) situated to the north from site OL 15, the influence of zinc−works is rather uncertain. Because of the time of occurrence and the distance form zinc−work, the reductions observed here seem to be the reaction to the other factor – perhaps the local source of pollution. To explain this matter further studies in this region should be done.
