Glony aerofityczne w rezerwacie „Mokry Bór”

Abstract

The results of investigation on aerophytic algae grown on different tree species in the area of the „Mokry Bor” reserve carried in February 1995. Among the found green algae Apatococcus lobatus played important role. It occurred on the surface of nearly all examined trees creating dark green coatings on the tree barks (excluding Carpinus be lulus). On Abies and Picea apart from Apatococcus also other synantropic green alga occurred Gloeotila protogenita. They were accompanied by the following species: Chlorella vulgaris, Ch. ellipsoidea, Klebsormidium flaccidum, Stichococcus bacillaris, Pseudococcomyxa simplex and Heterothrix exilis, representing probably previous natural communities. Obtained ultrastructures of cells of Apatococcus showed inside some specimens presence of fungus haustorium, which however did not affect cellular structures of this algae. This form of symbiosis has not been observed so far in the case of this green alga. Characteristic ultrastructure observed in the green alga Gloeotila (in particular the thick layer of mucus surrounding the vegetative cells) proves presence on this area of a typical land form containing pyrenoid of a specific structure. Its land character is also proven by the reproduction ways.

W tej pracy przedstawione zostały wyniki badań dotyczące glonów aerofitycznych, występujących na różnych drzewach na terenie rezerwatu ścisłego „Mokry Bór” (Świętokrzyski Park Narodowy). Materiał został zebrany w lutym 1995 r. Stwierdzono na prawie wszystkich badanych drzewach (z wyjątkiem Carpinus betulus) obecność Apatococcus lobatus.
