SPORE MORPHOLOGY OF SOME BARTRAMIACEAE SPECIES (BRYOPHYTA) IN TURKEY

Abstract

In this study, spore morphology of Bartramia pomiformis Hedw., B. halleriana Hedw., Philonotis calcarea (Bruch & Schimp.) Schimp. and Plagiopus oederianus (Sw.) H.A.Crum & L.E.Anderson were examined by light microscopy (LM) and scanning electron microscopy (SEM). All spores are small, the length of the polar axis (P) is between 12.36 µm and 19.14 µm, equatorial diameter (E) is between 19.59 µm and 26.23 µm. The smallest spores of them are Philonotis calcarea and the biggest spores of them are Plagiopus oederianus. The shapes of the spores are determined as suboblate for Bartramia pomiformis, B. halleriana, and oblate for Philonotis calcarea, Plagiopus oederianus. Verrucategranulate, gemmate-microecinate, perforate, gemmate-pilate and verrucate ornamentation types were observed on the distal pole. In addition to spore morphology, capsule structures were also examined and were photographed with SEM. As a result, the spore size, shapes, ornamentation types and the capsule structures show some differences among these species and these differences can be used as distinctive characters in the identifications of them
