    Opis:
    The possibility of mistletoe growth on our native oaks is often questioned. There is a hypothesis that the reports of mistletoe on oak, existing both in scientific literature and in culture, are a mistake and concern another semi-parasite: European loranth, which is hosted by both our oaks: the common and the sessile oaks. The article briefly reviews the information on the occurrence of mistletoe on native oak species, as the phenomenon has been observed to a very limited extent in Great Britain and France. Moreover, attempts are being made to sow mistletoe on oak trees and cultivate it further.

    Opis:
    Mistletoe (Viscum album L.) is a semi−parasitic plant and, as long as it is not present in large quantities, it does not pose a lethal threat to trees. Due to its ability to carry out photosynthesis, its effect on the host is negligible. However, recent droughts have made heavy impact on forests and mistletoe in recent years began to appear on a larger scale in regions and in places where it has never been a threat before. For this reason, there is an urgent need to broaden our knowledge about this species. This work includes a review of the literature on the biology and ecology of mistletoe. The main purpose of this research is to analyze the methods for assessing the number of mistletoe on individual trees and in the stands as well as to prepare new method adapted to Polish conditions. New method that was proposed is based on random sample plots, each consisting of 15 trees on which impact of mistletoe is assessed. On every sample plot the mistletoe occurrence, location in the crown, estimate of the percentage within the crown and the number of mistletoe on a tree is assessed. In addition, for further analysis, information on stand (forest habitat type, site index) as well as measured trees (age, diameter, Kraft class, crown length, loss of assimilation apparatus, crown type) levels is recorded.

    Opis:
    The forest area infected by mistletoe (Viscum album L.) in Europe has been increasing in recent years. The highest potential threat is posed by Viscum album subsp. austriacum, a parasite of Pinus sylvestris, and V. album subsp. abietis, a parasite of Abies alba. The paper presents a literature review related to biology, ecology and possible methods of limiting the negative impact of mistletoe on forest management. The vast majority of studies indicate that the presence of mistletoe negatively affects the growth as well as defensive and reproductive capabilities of trees. Due to the wasteful water management of the parasite, infected trees are particularly vulnerable to weakening during periods of drought. Mistletoe is a heliophilous taxon and forest breeding treatments should reduce light intensity in the forest canopy. Foresters should resign from leaving individual and group seed trees in forest stands inhabited by mistletoe after the cuts, because they may be a source of seeds for the parasite invasion to the neighboring stands. The most effective method against mistletoe is cutting out the infected trees. However, removal of individual trees in forest stand may be difficult, because the most often they are the dominant and hence the most vulnerable trees in the forest management. Mistletoe is also noticeable when the number of infected trees is already very large and they cannot be removed without disturbing the stability of the forest stand. Therefore, there is an urgent need to develop methods for monitoring stands for early detection of threat. Remote sensing methods can be very useful. It is also necessary to develop management strategies with mistletoe infected stands.

    Opis:
    European mistletoe (Viscum album L.) is a semi−parasitic plant attacking selected tree species. It adversely affects the functioning of its hosts especially at water management level. Scots pine infestation by mistletoe subspecies Viscum album ssp. austriacum becomes more and more common. Mistletoe has been proven to have a negative impact on Scots pine cones, seedlings and seeds quality. Thus, we decided to analyze the influence of this parasite on the radial growth of the Scots pine. The following hypotheses were tested: 1) mistletoe has negative effects on the radial growth of trees, and 2) trees infested with mistletoe are more sensitive to climatic factors, especially to low precipitation. The study was performed in western Poland, in the Scots pine excluded seed stand in the Bolewice Forest District (52°23'54'N, 16°05'01'E). We determined the association between pine radial growth and climatic factors (precipitation and temperature). Wood samples(cores) were taken from 15 infested and 15 non−infested trees and subjected to the standard procedure of dendrochronological dating. The study showed that radial growth rate decreased more intensively in trees infested by mistletoes, but it did not show the different climatic response of trees infested and non−infested, probably due to a short time of infestation. Scots pine is the main economic forest species in Poland and mistletoe can significantly affect the growth and development of pines. It is necessary to investigate the impact of mistletoe on stands and ecosystems, as well as to determine the methods of prevention and management of mistletoe tree stands.

    Opis:
    Mistletoe is semiparasite adversely affecting the functioning of their hosts especially at water management level. So far, there have been no reports about the impact of mistletoe on seeds from any host. The aim of the work was to evaluate the effect of the presence of mistletoe on the quality of the seeds of Scots pine (Pinus sylvestris). Unopened cones from infected and uninfected trees were collected in April 2015 in the Excluded Seed Stand in Bolewice Forest District (52°2354.347N; 16°0501.978E). Measurements of cones and seeds were made. Some seeds were used for pot experiment, where the seedlings were planted from May to October 2015. On the second part of the seeds in the end of July and August germination tests were made. The size and mass of the cones, the number and weight of seeds, and the height and weight of the seedlings were lower for the material collected from the mistletoe trees. The differences were not large but statistically significant (tabs. 1 and 2). The results showed that mistletoe has a negative impact on the parameters of cones, seedlings and seeds quality.
