Abstract

Abstract. Sofiyanti N, Isda MN, Juliantari E, Pranata S, Suriatno R. 2019. The inventory and spore morphology of ferns from Bengkalis Island, Riau Province, Indonesia. Biodiversitas 20: 3223-3236. Bengkalis Island is one of main islands at coastal region of Riau Province, Indonesia. The first fern inventory had been conducted on this island, to identify the fern checklist as well as examined the morphology of their spores. Samples were collected from 2 subdistricts and 12 study sites, using exploration method. The spore specimens were coated using AU, before observation using Scanning Electron Microscopy (SEM). A total of 22 fern species are recorded from Bengkalis Islands. These species belong to 3 orders, i.e. Gleicheniales (1 species), Polypodiales (20 species) and Schizaeales (1 species). The spore characteristic indicated similar unity of spore, i.e. monad spore, with triangular, subtriangular, tetrahedral and reniform shape. Three basic types of spore have been observed, i.e. monolete, dilete, and trilete. The spore class observed in this study are small (22 ± 0.88 µm), medium (27.35 ± 1.45 to 47.85 ± 0.88 µm) and large (51.34 ± 1.83 to 53.8 ± 1.81 µm). The ornamentation of perisphore is the main character to distinguished species within one genus.

Kajian Fenetik Tumbuhan Paku (Pteridofita) di Kecamatan Benai Kabupaten Kuantan Singingi, Provinsi Riau

“…Tumbuhan paku merupakan golongan tumbuhan yang mempunyai keanekaragaman jenis yang tinggi. Golongan tumbuhan paku berkembang biak dengan spora namun telah memiliki berkas pengangkut (Sofiyanti, 2019), oleh karena itu tumbuhan paku digolongkan ke dalam tumbuhan vascular, sebagian besar jenis tumbuhan paku sudah mulai dapat dibedakan antara batang, daun dan akar (Sofiyanti et al, 2019). Menurut Astuti et al (2017), jumlah jenis tumbuhan paku yang ditemukan di dunia adalah sekitar ± 10.000 spesies, kurang lebih ± 1.300 di temukan di Indonesia (Imaniar et al, 2017).…”

Isolation and Analysis of Bioactive Compounds Endophytic Bacteria of Sea Fern (Acrtostichum aureum L.) from Bengkalis Island, Riau

“…Satu-satunya tumbuhan paku yang sering di kelompokkan ke mangrove adalah paku laut Acrostichum aureum L. dengan famili Pteridaceae karena habitat tumbuhnya sama. Hasil inventarisasi Sofiyanti et al, (2019) di Pulau Bengkalis ada 22 species paku salah satunya paku laut. Isolasi mikroba endofit dari paku-pakuan di Indonesia sebelumnya telah di laporkan diantaranya jamur endofit dari tumbuhan paku Asplenium nidus (Suhartina Kandou & Singkoh, 2018), endofit bakteri dari tumbuhan paku air (Salvinia molesta), paku terestrial (Pteris ensiformis) dan paku epifit (Drymoglossum pilosolloides) oleh Asmoro & Munif (2019).…”

Diversity, structure and composition of pteridophyte in varying habitats in Karimun Besar Island, Riau Islands Province, Indonesia

“…However, study on plant diversity, as well as pteridophyte, from Karimun Besar Island has never been recorded, nor from the other island at Riau Islands Province. Only limited studies on pteridophyte had been reported from coastal areas from nearby province (Riau Province) (Sofiyanti et al 2019a;2019b).…”

“…Pteridophyte is a plant group of seedless (Mir et al 2015) and spore producing plant (Lashin 2012;Barrington et al 2015;Gómez-Noguez et al 2016;Sofiyanti et al 2019b). According to Konrat et al (2011), pteridophytes refer to vascular cryptogamic plants due to the presence of vascular bundle and spore.…”
