Isolasi dan Identifikasi Fungi Mikoriza Arbuskula (FMA) pada Berbagai Varietas dan Umur Kopi Arabika (Coffea Arabica L.) di Kecamatan Timang Gajah Kabupaten Bener Meriah

Abstrak: Fungi mikoriza arbuskula (FMA) merupakan tipe asosiasi yang tersebar sangat luas, fungi ini memiliki peran dan manfaat penting dalam dunia pertanian. Penelitian bertujuan mengetahui keanekaragaman FMA, jumlah spesies spora kolonisasi FMA pada rizosfer berbagai varietas umur tanaman kopi arabika di Kecamatan Timang Gajah, Kabupaten Bener Meriah. Penilitian dilaksanakan perkebunan rakyat Desa Lampahan Barat Mude Benara, Masing-masing diambil sebanyak 3 titik, sehingga didapatkan 24 sampel. Sampel tanah tersebut digunakan untuk mengisolasi jenis terdapat lahan tersebut. Analisis beberapa sifat kimia fisika juga dilakukan mendapatkan data pendukung seperti, pH H2O, C-Organik, N-Total, P-Tersedia, KTK, Tekstur. terhadap sampel komposit dari setiap titik sampel, arabika. Parameter pengamatan meliputi: Kepadatan identifikasi FMA. Hasil menunjukkan tiga genus didapat Gajah yaitu Glomus, Acaulospora dan, Gigaspora.Terdapat Genus Glomus dua spesies, sedangkan Gigaspora empat spesies. terbanyak ditemukan Tim-Tim berumur lima tahun. Kolonisasi akar tergolong kriteria rendah hingga rendah. Isolation and Identification of Arbuscular Mycorrhizal (AMF) in Various Varieties Ages Arabica Coffee (Coffea arabica L.) District, Meriah RegencyAbstract. mycorrhizal are a very widespread type association, these which have important roles benefits agriculture. The research aimed to determine the diversity AMF, number AMF spore species, colonization rhizosphere various varieties ages coffee plants Regency. was carried out plantations West Benara Village, points were taken for each variety age, so that samples obtained. isolated by using soil found land. chemical physical analysis properties also obtain supporting such as pH, C-Organic, P-Available, CEC, Texture. Analysis several on composite from sample point, age coffee. Observation parameters included: density, identification types, colonization. results showed there three genera obtained District namely Acaulospora, and, Gigaspora. There two species while four highest density spores five-year-old plant. roots classified low criteria.
