Abstrak (Berisi Bastraknya saja, Judul dan Nama Tidak Boleh di Masukan)
Abstrak Penggunaan ektomikoriza yang diaplikasikan pada beberapa komposisi media diharapkan dapat meningkatkan pertumbuhan semai meranti tembaga. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian fungi ektomikoriza Scleroderma columnare dan komposisi media, serta mengetahui interaksi antara pemberian Scleroderma columnare dan komposisi media terhadap pertumbuhan semai meranti tembaga. Penelitian dilaksanakan pada bulan Juni sampai November 2011 di Rumah Kaca Universitas Lampung selama 150 hari. Penelitian disusun secara Faktorial (3x4) dalam Rancangan Acak Lengkap (RAL) dengan 3 ulangan. Faktor I adalah volume spora terdiri atas 0ml; 5ml; dan 10ml, sedangkan faktor II adalah komposisi media terdiri atas tanah (100%); tanah : serbuk gergaji kayu cempaka (80%:20%); tanah : serbuk gergaji kayu cempaka (60%:40%); tanah : serbuk gergaji kayu cempaka (40%:60%). Variabel yang diamati adalah pertambahan tinggi, pertambahan diameter, jumlah daun, panjang akar, persentase akar bermikoriza, berat kering total, dan ratio tajuk dan akar. Hasil penelitian menunjukkan bahwa inokulasi ektomikoriza berpengaruh nyata terhadap pertambahan tinggi dan persentase akar bermikoriza. Komposisi media berpengaruh nyata terhadap pertambahan tinggi tanaman, jumlah daun, dan ratio tajuk dan akar, sedangkan interaksi antara inokulasi ektomikoriza pada beberapa komposisi media hanya memberikan pengaruh nyata pada ratio tajuk dan akar semai meranti tembaga. Perlakuan terbaik untuk pertumbuhan semai meranti tembaga adalah inokulasi 5 ml suspensi spora yang diaplikasikan pada media tanah 100%. Kata kunci : ektomikoriza, media semai, meranti tembaga, Scleroderma columnare Abstract Ectomycorrhiza application to some media compositions expected to increased seedling growth of Shorea leprosula. This research aims to detennine the effect of fungi ektomikoriza Scleroderma columnare and composition of the media, and to know the interaction between application ofScleroderma columnare and media composition on the growth of meranti tembaga seedlings. The research was conducted in June until November 2011 in Lampung University Greenhouse. The research used Factorial (3x4) in Completely Randomized Design (CRD) with three replications. .The first factor was composed of spora volume 0 ml; 5 ml, and 10 ml, while the second factor was the composition of media consisting of soil (100%); soil and cempaka wood sawdust (80%: 20%); soil and cempaka wood sawdust (60 %: 40%); soil and cempaka wood sawdust (40%: 60%). Observed variables were high accretion, diameter accretion, leaf number, root length, root percentage of mycorrhizal, total dry weight, and ratio of crown and root. The resulted of this research was that the inoculation ectomycorrhiza significantly affect plant height increment and the root percentage of mycorrhizal. Media composition significantly affect plant height increment, leaf number, and ratio of crown and root, while the interaction between inoculation ektomikoriza on the composition of the media only gave some real influence on the ratio of crown and root of Shorea leprosula seedlings. The best treatment to increased the growth of Shorea leprosula seedling was inoculated 5 ml of susupension spora combined with the soil media 100%. Key words : ectomycorrhiza, Shorea leprosula, Scleroderma columnare, seedling media.
