Rozwój botaniki w Uniwersytecie Lwowskim (od końca XVIII w. do roku 1941) [Development of botany at the University of Lvov (since 18th century until 1941)]
Irena Sawczyn
In this article the outline of the history of botany in the University of Lvov is presented. The first lectures of botany were begun at the end of 18th century. In 1852 professor Łobarzewski founded the independent department of botany. Such famous botanists as B. Hacquet, S. Schivereck, M. Raciborski, S. Kulczyński and others taught there botany during the different historical periods of the University. These lectures had been lasted till the beginning of the Second World War.

Zmiany liczebności populacji roślin o różnych strategiach reprodukcyjnych w procesie sukcesji [Changes of population numbers of plants with different reproduction strategies in the process of succession]
Emilia Brzosko
Problems concerning population dynamics and ways of solving them have been discussed in a number of papers. It is known from many sources that population dynamics is the main cause of vegetation changes. Dynamics of plant populations and its role in vegetation processes depends on growth form of plants. Another factor determining population dynamics is a mode of reproduction. Clonal plants characterized by two types of reproduction play a main role in the process of succession.
Słowa kluczowe: growth form, type of reproduction, seeds, seedlings

Wawelia – historia i nowe odkrycia [Wawelia – the history and a current news]
Barbara Gumińska
The article presents a brief history of our knowledge of the fungus Wawelia. This genus is represented by 5 species: W. regia, W. octospora, W. effusa, W. argentea and W. microspora. All these fungi are hitherto known only from Europe: from Poland, England, Sweden and Hungary. All species are coprophilous and develop their fruit-bodies on rabbit, hare and deer dung. Significant is the fact that all these species have been described only from incubated dung samples.
Słowa kluczowe: Wawelia, coprophilous fungi, distribution, macroscopic and microscopic details

Flawonoidy roślinne jako związki biochemicznie czynne [Plant flavonoids as biochemical active compounds]
Urszula Małopepsza, Hentyk Urbanek
Flavonoids are a group of polyphenolic compounds, diverse in chemical structure and properties, commonly found in plants. The recent explosion of interest in the bioactivity of the flavonoids is due to the potential health benefits of these polyphenolic components of major dietary constituents. This article will attempt to summarize the published data concerning the biological properties of the flavonoids and their functions in plants. Special attention has been paid to flavonoids as UV light damage and antioxidant protectants. Their antioxidant activity and activity-structure relationships are discussed. The antioxidant activity of flavonoids is connected, at least in part, with their antiintlamatory, antimutagenic, anticarcinogenic, antiatherosclerotic actions and it explains tremendous interest in using them in medicine and disease control. The role of flavonoids as signal molecules for beneficial microorganisms in rhisosphere, attractants of animals involved in fertilization, allelopatic agents, pest and pathogen protectants are also regarded.
