Effects of Growth of Some Cyanoprokaryota and Diatom Species on the Growth of Two Mosses

Abstract

Cyanoprokaryotic taxa Nostoc paludosum Kützing ex Bornet & Flahault and Nostoc punctiforme (Kützing) Hariot may have allelopathic effects on two moss taxa, Bryum subapiculatum Hampe and Funaria hygrometrica Hedwig, grown in vitro under 66% and 99% percentages of soil water holding capacity. Nostoc filaments destroyed protonema of B. subapiculatum and arrested gametophores development of F. hygrometrica under these conditions. Colonies of the diatom Navicula cryptocephala var. veneta (Kützing) Grun. grew in a large amount and delayed the growth of B. subapiculatum.
