Radyatama, Cahya Ingtyas (2018) Ketahanan Enam Varietas Kacang Panjang (Vigna Sinensis L.) Terhadap Infeksi Virus Bcmv (Bean Common Mosaic Virus). Sarjana thesis, Universitas Brawijaya.
Abstract
Penelitian ini dilakukan untuk mengetahui ketahanan enam varietas kacang panjang terhadap infeksi virus BCMV dan mengetahui pengaruh infksi virus BCMV terhadap pertumbuhan dan produksi tanaman kacang panjang. Varietas yang digunakan adalah varietas Maraton, varietas Kanton, varietas Prima, varietas Persada, varietas Parade, dan varietas Katrina. Penelitian dilakukan pada bulan Mei hingga Juli 2018 di laboratorium penyakit tumbuhan jurusan HPT dan rumah kawat Fakultas Pertanian Universitas Brawijaya Penelitian diawali dengan melakukan persiapan penelitian yang meliputi penyediaan inokulum, identifikasi virus menggunakan tanaman indikator, dan persiapan media tanam. Pelaksanaan penelitian terdiri dari persiapan benih dan penanaman tanaman uji, pembuatan sap BCMV, inokulasi BCMV pada tanaman kacang panjang, pemeliharaan tanaman, dan panen. Variabel pengamatan terdiri dari masa inkubasi dan gejala penyakit, intensitas serangan penyakit, pertumbuhan tanaman yang meliputi tinggi tanaman dan jumlah daun, serta produksi tanaman yang meliputi jumlah polong, bobot basah polong, bobot kering polong, panjang polong, dan bobot 25 biji per tanaman. Data hasil pengamatan dianalisis menggunakan uji F pada taraf kesalahan 5% dan uji DMRT (Duncan’s Multiple Range Test) pada taraf 5%. Setelah itu, dihitung tingkat ketahanan dari masing-masing varietas tanaman kacang panjang. Hasil dari penelitian menunjukkan bahwa keenam varietas tanaman kacang panjang memiliki tingkat ketahanan yang berbeda-beda. Masa inkubasi serangan BCMV tercepat adalah pada tanaman kacang panjang varietas Parade, yaitu 6,6 hari. Gejala yang terjadi pada setiap varietas kacang panjang juga menunjukkan perbedaan. Gejala yang muncul pada tanaman kacang panjang berupa mosaik hijau kekuningan lalu gejala lanjut yang dapat dilihat secara fisik adalah penebalan tulang daun yang menyebabkan permukaan daun tampak tidak rata. Intensitas serangan tertinggi adalah varietas Parade dengan persentase sebesar 55,62%. Dari rerata variabel pengamatan dan perhitungan ketahanan tanaman, didapatkan tingkat ketahanan yang berbeda-beda dari keenam varitas kacang panjang. Terdapat empat kategori ketahanan, yaitu tahan, sedang, rentan, dan sangat rentan. Varietas Parade dan varietas Katrina masuk kedalam kategori tahan, varietas Prima masuk kedalam kategori rentan, sedangkan varietas Maraton, varietas Kanton, dan varietas Parade masuk kedalam kategori sangat rentan. Kesimpulan yang didapatkan dari penelitian ini adalah keenam varietas yang diuji ketahanannya memiliki kategori tanaman yang berbeda-beda. Varietas Persada dan varietas Katrina masuk kedalam kategori tahan, varietas Prima masuk kedalam kategori rentan, varietas maraton, varietas Primas, dan varietas Parade masuk kedalam kategori sangat rentan. Selain itu, pertumbuhan dan produksi tanaman paling baik adalah varietas Persada.
English Abstract
This study was conducted to determine the resistance of six long bean varieties to BCMV virus infection and determine the effect of BCMV virus infection on the growth and production of long bean plants. Varieties used are varieties of Marathon, Kanton varieties, Prima varieties, Persada varieties, Parade varieties, and Katrina varieties. The study was conducted from May to July 2018 at the plant disease laboratory majoring in HPT and wire house of the Faculty of Agriculture, University of Brawijaya The study began with the preparation of research which included the provision of inoculums, identification of viruses using indicator plants, and preparation of planting media. The research consisted of seed preparation and planting of test plants, making BCMV sap, BCMV inoculation on long bean plants, crop maintenance, and harvesting. Observation variables consist of incubation period and disease symptoms, disease attack intensity, plant growth including plant height and number of leaves, as well as crop production which includes number of pods, weight of wet pods, dry weight of pods, length of pods, and weight of 25 seeds per plant. Observation data were analyzed using F test at 5% error level and DMRT (Duncan Multiple Multiple Range Test) at 5% level. After that, the level of resistance of each long bean crop variety was calculated. The results of the study show that the six varieties of long bean plants have different levels of resistance. The fastest BCMV attack incubation period was in the long bean variety Parade, which was 6.6 days. Symptoms that occur in each long bean variety also show differences. Symptoms that appear on the long bean plant in the form of yellowish green mosaic then further symptoms that can be seen physically are thickening of the leaf bone which causes the leaf surface to appear uneven. The highest attack intensity is the Parade variety with a percentage of 55.62%. From the mean of observation variables and the calculation of plant resistance, obtained different levels of resistance from the six long bean varieties. There are four categories of resilience, which are resistant, medium, vulnerable, and very vulnerable. Parade varieties and Katrina varieties were categorized as resistant, Prima varieties were included in the vulnerable category, while the Marathon, Kanton varieties, and Parade varieties were categorized as very vulnerable. The conclusion obtained from this study is that the six varieties that have been tested for resistance have different categories of plants. Persada varieties and Katrina varieties are categorized as resistant, Prima varieties are included in the vulnerable category, marathon varieties, Primas varieties, and Parade varieties are categorized as very vulnerable. In addition, the best plant growth and production is Persada variety
