Vojtkó, András: Relationships between the morphology of the spores of Hungarian Hepaticae species and their strategy types

Studia bot. hung. 27-28, pp. 109-115, 1996-97(1998) RELATIONSHIPS BETWEEN THE MORPHOLOGY OF THE SPORES OF HUNGARIAN HEPATICAE SPECIES AND THEIR STRATEGY TYPES A. VOJTKÓ Dept. of Botany, Eszterházy Károly Teachers ' Training College H-3301 Eger, Pf. 43, Hungary The paper includes the strategy types of the Hungarian Hepaticae species from the point of view of spore morphology of the taxa. The comparison is based on the data of 46 species. The most important strategy types are: colonist, annuals, perennial shuttles, perennial stayers and short life shuttles. Key words: life strategy, Hepaticae, spore wall, spore morphology INTRODUCTION We can get closer to the answers for taxonomic and systematic questions with the morphological characterization of the spores of bryophytes (CLARKE 1979, SORSA and KOPONEN 1973, MOGENSEN 1981). In addition to it some species can be classified only on the basis of their spores. At the same time the spores of different sizes get their own species to different reproductive chances so the strategies of the species will be different (DURING 1979, RICHARDSON 1981). One of the most important elements of life strategy is the reproduction tactics and the most essential parts of it are the size and number of the spores. The small size of the spores is paired with the large number of them so it guarantees the quickest and the widest distribution. The disadvantage of the small size is that they are surrended to the air current (ZANTEN 1978, RICHARDSON 1981). The topic of the paper covers these themes and the author would like to serve data in order to know better the life strategy of Hepaticae. MATERIALS AND METHODS The examination is based on the morphological characterization of the spores of the Hungarian Hepaticae which could be found in the herbaria and on the results of the descriptions in the literature (JOVET-AST 1972, 1986, BOROS
