Eksplorasi Mikoriza Vesikular Arbuskular (MVA) Indigenous pada Tanah Aluvial di Kabupaten Pamekasan Madura

Abstract

Mikoriza merupakan simbion mutualistik antara jamur dengan akar tanaman. Kondisi lingkungan yang bervariasi di Indonesia dapat memungkinkan beranekaragamnya komposisi genus mikoriza pada suatu lahan. Penelitian ini bertujuan untuk mengetahui komposisi genus mikoriza vesikular arbuskular indigenous apa sajakah yang diperoleh dari jenis tanah aluvial di Pamekasan Madura.Tanah aluvial diisolasi menggunakan metode tuang saring basah dilanjutkan dengan teknik sentrifugasi sukrosa. Identifikasi dilakukan dengan menggunakan buku panduan Working with Mycorrhizas in Forestry and Agriculture.Hasil penelitian menunjukkan genus mikoriza vesikular arbuskular yang ditemukan tergolong ke dalam tiga genus yaitu Glomus, Gigaspora, dan Acaulospora. Jumlah spora mikoriza tertinggi diperoleh di Pademawu sebesar 11 spora/100 gr dengan 5 tipe genus Glomus, 3 tipe genus Acaulospora dan 3 tipe genus Gigaspora. Sedangkan di Pamekasan sebesar 7 spora/100 gr dengan 6 tipe genus Glomus dan 1 tipe genus Gigaspora. Dan di Tlanakan 9 spora/100 gr dengan 5 tipe genus Glomus dan 4 tipe genus Acaulospora
