Characterization of Terrestrial Spores Fern Plants From Wildlife Highland “Yang” The Argopuro Mountain

Abstract

This study was conducted to determine the spore characteristics of terrestrial fern plants. It covered in highland “Yang" wildlife moss forest, Argopuro Mountains. The specimens of terrestrial fern collections were carried out by a structured random method along 2 km mossforest climbing route that was divided into 20 points. In each pointwas 100 meters away then made a rectangular plot with a length 15 meters and 6 meters wide. In each plot measurements of abiotic data such as temperature, humidity, light intensity, geospatial location and site altitude. The spores obtained were prepared by using acetolysis, then it observed under a microscope with magnification 400 times. Spore parameters were type, shape, size, and exinornamentation. Twelve kinds of terrestrial fern plants with 2 types of spores were trilete and monolete. The trilete spore was found in a single fern plant of Pteristripita. While monolete type were found in Aspleniums colopendrium, Asplenium excisum, Asplenium normale, Blechnum nudum, Lastreopsis rufescens, Lastreopsis munita, Lastreopsiss mithiana, Lastreop sisgrayi, Sticherus lobatus, Diplazium pallidum and Athyrium mearnsianum. The spores form observed were suboblasts (1 species), prolate (3 types), peroblics (2 types), oblate (1 type) and subspheroidal (5 types) with 5 exine ornamentation forms were psilate, verrucate, scabrate, echinate and regulate. This study that characteristics spore of fern plants in moss forest, Argopuro Mountains for better understanding the key characters from morphological features of spore fern plant.
