The findings of the investigations concern Viscum album L., Viscaceae. The knowledge
status related to its taxonomic position, phylogenesis and origin on
the European continent, as well as its endophytic system have been
analysed. Physiological issues included the mechanism of uptake and
accumulation of chemical elements – both those necessary for living and
toxic ones. It has been found out that common mistletoe produces over
100 organic compounds. A wide range of Viscum album hosts in Poland (194
taxa) has been analysed. In Poland there are 3 Viscum album subspecies (subsp. abietis, subsp. album and subsp. austriacum). It has been found
that the number of sites of the mentioned subspecies amounts to 4784.
The most frequent in occurrence is V. a. subsp. album (78,41% of sites).
During the author's investigation conducted in Olsztyn Lake District
(Poland) in 1989, 900 specimens of V. album were collected,
their 6 traits and population structure were analysed. The intensity of
fructification and biomass production, depending on biotic and abiotic
factors, were studied. In addition, the age and sex structures were
investigated. Within the age structure, 6 age classes were
distinguished (I‑VI). The age class II specimens (10–14 years) and
class III specimens (15–19 years) constituted 87% of the whole
population (900 specimens). Within the sex structure, a dominations of
females specimens over male specimens (M:F = 1:7.55, sex ratio) was
found. Besides, the utilization, control and protection of Viscum album were analysed. Its
traits against other parasitic species were compared and its role in
biological sciences was analysed.
