Application of Arbuscular Mycorrhiza from Senaru Forest Rhizosphere for Gyrinops versteegii Germination and Growth

Abstract

The aims of this research are to apply Senaru forest rhizosphere on Kabupaten Lombok Barat West Nusa Tenggara as Mycorrhiza inoculants for Gyrinops versteegii germination and growth. Rhizosphere sample was taken from ten sampling spot on Senaru forest between Latitude: 08o18.808’ S – 08o19.174’ S and Longitude: 116o24.138’ E – 116o24.181’E. This study employed Factorial Experiment Design with 2 Factor including: Medium Composition (M) and Mychorizza Inoculant (I). There were 5 media composition: M1 (sand), M2 (soil:sand = 1:2), M3 (soil:sand = 1:1), M4 (soil:sand = 2:1), M5 (soil). There were 2 types of Inoculation: I1 (without inoculant) and I2 (innoculant from senaru Rhizosphere). Growth parameters observed in this study were: germination percentage, stem length, stem diameter and root colonization. Germination percentage of G. versteegii seeds in all growth media are below 60 % which could be classified as low germination rate. Also germination from media without rhizosphere is higher than germination from media with rhizosphere. On the other hand, G. versteegii growth on rhizosphere media is slightly higher than growth of G. versteegii on media without rhizosphere based on stem diameter and length measurement. It tends that medium composition with higher sand proportion tended to gives better germination and growth rate of G. verteegii. Myorrhiza colonization on G. versteegii root was higher in media with rhizosphere addition. It could be concluded that Application of Senaru rhizosphere containing Mycorrhiza increases G. versteegii growth but not its germination percentage. This research enrich knowledge in biological science about asociation of mycorrhiza with G. versteegii especially on its growth and germination

Bio-Induksi Ranting Cabang Gaharu (Gyrinops Versteegii) Di Perkebunan Gaharu Desa Pejaring Lombok Timur

“…Untuk wilayah pulau Lombok, spesies ini tersebar di wilayah Lombok bagian barat (Iswantari dkk. 2017), Lombok bagian utara terutama hutan Senaru (Wangiyana & Malik, 2018) serta Lombok bagian timur (Wangiyana dkk. 2018).…”

PENGARUH KOMPOSISI MEDIA TUMBUH DAN BIOFERTILIZER TERHADAP PERTUMBUHAN BIBIT GAHARU (Gyrinops versteegii) ASAL KEKAIT PUNCANG

“…Namun, untuk selisih pengukuran kurang dari 2 bulan, variasi tinggi batangnya tidak berbeda signifikan. (Wangiyana and Malik, 2018) Karena belum ada standard baku terkait tinggi batang bibit gaharu, maka untuk menganlisis efektivitas perlakuan terhadap pertumbuhan bibit gaharu dilakukan dengan ANOVA. Berdasarkan uji ANOVA (Tabel 3), hanya faktor utama yang berpengaruh signifikan terhadap tinggi batang bibit gaharu.…”

“…Penelitian (Aji, Irwan Mahakam Lesmono;Sutriono, 2015) mengaplikasikan intensitas cahaya dalam mengoptimalkan pertumbuhan bibit gaharu. Penellitian (Wangiyana and Malik, 2018) mengaplikasikan formulasi media tumbuh dalam pertumbuhan bibit gaharu.…”

PEGARUH MEDIA TERHADAP PERTUMBUHAN BIBIT JAMBU METE (Anacardium occidental. L)

“…Secara umum, dapat dikatakan bahwa laju pertambahan tinggi bibit pada minggu ke -0 sampai minggu ke 8 tidak menunjukkan perbedaan yang signifikan antar media pertumbuhan yang berbeda. Dalam hal ini, waktu pengamatan 8 minggu masih relatif singkat untuk melakukan pengamatan terhadap pertumbuhan bibit tanaman hutan (Wangiyana dan Malik, 2018). Gambar 1.…”
