Bawana, Candra Tri (2018) Eksplorasi Jamur Endofit Akar Dan Uji Ketahanan Varietas Tanaman Jagung Hibrida (Zea Mays L.) Terhadap Penyakit Bulai (Peronosclerospora Maydis). Sarjana thesis, Universitas Brawijaya.
Abstract
Jagung (Zea mays L.) merupakan salah satu tanaman serealia yang strategis karena termasuk tanaman yang banyak dibudidayakan di Negara tropis di dunia. Dibidang ekspor dan impor tanaman jagung memiliki banyak permintaan dari konsumen karena mempunyai potensi yang baik sebagaimana dimanfaatkan dalam berbagai kebutuhan dalam masyarakat. Penurunan produksi pada jagung tidak hanya dipengaruhi oleh faktor lingkungan. Salah satu faktor penyebab menurunnya kualitas dan kuantitas tanaman jagung di Indonesia adalah penyakit bulai (downy mildew) yang disebabkan oleh patogen Peronosclerospora spp. Penelitian bertujuan untuk mengetahui jamur endofit yang terdapat pada bagianbagian tanaman dan hubungannya terhadap varietas tanaman uji, terutama pada bagian akar tanaman, sehingga dapat menekan perkembangan penyakit bulai pada tanaman jagung. Penelitian ini dilaksanakan di kebun percobaan milik PT BISI International, Tbk Desa Kambingan, Kecamatan Pagu, Kabupaten Kediri, Jawa Timur. Daerah tersebut memiliki suhu 28º - 33ºC dan kelembaban nisbi per tahun rata-rata 74-86%. Penelitian untuk mengamati jamur endofit akar di Laboratorium Penyakit II, Jurusan Hama penyakit Tumbuhan, Universitas Brawijaya. Waktu pelaksanaan dimulai bulan November 2016 sampai dengan bulan juli 2017. Percobaan di lapang dilakukan menggunakan Rancangan Acak Kelompok (RAK) dengan 10 varietas dan tiga kali ulangan. Dari hasil penelitian diketahui bahwa intensitas serangan bulai tertinggi terdapat pada varietas PERTIWI 2 yaitu sebesar 78,21% dan intensitas yang terendah terdapat pada varietas P35 sebesar 3,56%. Sedangkan varietas menengah ada pada varietas BMD57, BMD58, BMD60, dan DK95 dengan persentase intensitas penyakit sebesar 21,25%, 28,03%, 22,54% dan 39,75%. Berdasarkan data produksi jagung pada setiap varietas berbeda nyata. Varietas BMD53 menghasilkan berat panen total sebesar 10,79 ton/ha dan berbeda nyata dengan seluruh varietas tanaman jagung yang lainnya, apabila dibandingkan dengan varietas PERTIWI 2.
English Abstract
Corn (Zea mays L.) is one of the most strategic cereal crops because it includes many cultivated plants in tropical countries in the world. In the field of export and import of corn crops have a lot of demand from consumers because it has the potential as utilized in various needs in the community. The decline in production in corn is not only influenced by environmental factors. One of the contributing factors to the declining quality and quantity of corn crops in Indonesia is the downy mildew caused by Peronosclerospora spp. The aim of this research is to find out the endophytic fungi found in the plant parts and their relation to the varieties of the test plant, especially on the root part of the plant, so that it can suppress the development of muddy disease in corn plant. This research was conducted in experimental garden of PT BISI International, Tbk Kambingan Village, Pagu Sub-district, Kediri Regency, East Java. The area has a temperature of 28º - 33ºC and the relative humidity per year averages 74-86%. Research to observe root endophytic fungi at Disease Laboratory II, Department of Plant Disease Pest, University of Brawijaya. The implementation time starts from November 2016 until July 2017. Field experiment was conducted using Group Random Design (RAK) with 10 varieties and three replications. From the research results it is known that the highest intensity of bulai attack is found in varieties of PERTIWI 2 that is 78.21% and the lowest intensity is found in P35 varieties of 3.56%. Medium varieties exist in varieties of BMD57, BMD58, BMD60, and DK95 with percentage of disease intensity of 21.25%, 28.03%, 22.54% and 39.75%. Based on data of maize production on each different varieties significantly. The BMD53 variety yields a total harvest weight of 10.79 tons /ha and is significantly different from all other varieties of maize crops, when compared to the variety PERTIWI 2.
