Abstract

Understanding the composition and diversity of arbuscular mycorrhizal fungi (AMF) is imperative for potentially enhancing their ecological role in different terrestrial ecosystems. Land use can have substantial effects on AMF species composition and diversity, but such effects have been explored less in tropical landscapes. In this study, we assessed the effects of disturbances on AMF species richness, observed the potential development of AMF types to produce mycorrhizal biofertilizer bioinoculants.  This study was conducted identifying and selecting AMFs was for the purpose of managing post-mining land in Bombana District, Southeast Sulawesi, Indonesia.  AMF spores collected from the field and trap culture were directly isolated and morphologically identified. A total of 15 AMF species were identified, including 11 species from field samples and 9 species from trap cultures. We noted that five AMF species were unique to field conditions and 5 AMF species were uniquely isolated from trap culture.  It appears that Glomeraceae family contributed the highest number of species in all land-use types.  Glomus sp. 1 was the most frequent species found in all land-use types. The Simpson’s index, Shannon index and evenness ranged from 1.60 ± 0.51 to 2.40 ± 0.40; 0.41 ± 0.17 to 0.62 ± 0.17; 0.25 ± 0.10 to 0.39 ± 0.11, respectively. In this study, we found three new records of AMF species including Entrophospora colombiana, Sclerocystis microcarpa and Glomus coronatum for Indonesia, i.e. from this study, it is clear that different land-use types affected AMF spore composition and species diversity.  All AMF species found in this study were then applied to the land to improve land quality.

Abstract

Jenis talas Colocasia esculenta (L.) Schott di Jawa mempunyai dua varietas botani yaitu C.esculenta var. esculenta yang umumnya tumbuh di dataian rendah dan C. esculenta var. antiquorum (Schott) Hubbard & Rehdei yang tumbuh liar di tepi-tepi sungai lereng pegunungan. Jenis lainnya yaitu C. gigantea (Bl.) Hook. f. (talas padang, sontrang) biasa tumbuh liar di hutan jati dan tawa. Perbungaan talas-talas budidaya jarang dihasilkan sehingga penanaman daii biji tidak lazim dilakukan dan perbanyakan tanaman lebih dikenal dengan anakan. Kaiena itu penelitian yang menyangkut biologi pembungaan dan penyerbukan kedua jenis Colocasia tersebut sampai saat ini sedikit sekali yang telah dilapoikan.

Abstract

The research was conducted with the aim to identify species of arbuscular mycorrhizal fungi (AMF) associated with nedum [Pericopsismooniana (Thw.) Thw.]. Soil sampling was conducted in 6 locations of nedum habitat in South-east Sulawesi. The results showed that nedum associated with 15 species of AMF that belonging to 5 families and 9 genera, Acaulosporaceae (Acaulospora scrobiculata and A. delicata), Claroideoglomeraceae (Claroideoglomus etunicatum), Glomeraceae (Glomus aggregatum, G. boreale, G. canadense, G. halonatum,G. versiforme, Rhizophagus diaphanus, R. fasciculatus, Sclerocystis clavispora and Septoglomus constrictum), Gigasporaceae (Racocetragregaria and Scutellospora auriglobosa), Ambisporaceae (Ambispora appendicula). The four species of AMF were found on nedum, i.e Glomus boreale, G. canadense, G. halonatum and Racocetra gregaria which were a new record for mycological collection of Indonesia.
