Aprillia, Erna (2018) Pengaruh Infeksi Cmv (Cucumber Mosaic Virus) Terhadap Morfologi Dan Pertumbuhan Tanaman Cabai Merah (Capsicum Annum L.). Sarjana thesis, Universitas Brawijaya.
Abstract
Cabai merupakan salah satu komoditas hortikultura yang banyak dibudidayakan oleh petani di Indonesia, karena memiliki harga jual yang tinggi. Kebutuhan cabai terus meningkat setiap tahun sejalan dengan meningkatnya jumlah penduduk dan berkembangnya industri yang membutuhkan bahan baku cabai. Budidaya tanaman cabai tidak lepas dari masalah menurunnya produksi cabai yang disebabkan oleh gangguan penyakit. Salah satu penyakit yang meneyerang cabai adalah Cucumber Mosaic Virus (CMV). Pengendalian penyakit yang disebabkan oleh virus sampai saat ini masih sangat sulit, hal ini disebabkan karena beberapa faktor salah satunya yaitu keragaman genetik CMV yang tinggi. Penelitian ini bertujuan untuk mengetahui pengaruh infeksi CMV terhadap morfologi dan pertumbuhan tanaman cabai merah yang dengan perbandingan perlakuan umur inokulasi yang berbeda.Penelitian ini dilaksanakan di Rumah Kawat dan Laboratorium Penyakit Tumbuhan milik Jurusan HPT, Fakultas Pertanian, Universitas Brawijaya, Malang. Percobaan dilakukan menggunakan metode Rancangan Acak Lengkap (RAL) berupa perlakuan terdiri atas inokulasi CMV 14 HST, 21 HST, 28 HST, dan kontrol negatif. Variabel pengamatan berupa masa inkubasi, intensitas serangan penyakit, tinggi tanaman, jumlah daun, dan total kadar klorofil. Infeksi CMV mempengaruhi perubahan morfologi dari tanaman yang menimbulkan gejala berupa mosaik, klorosis, kerdil, dan malformasi. Pada masa inkubasi tanaman diperoleh perlakuan inokulasi 14 HST paling cepat dan inokulasi 21 HST paling lambat. Intensitas penyakit tertinggi pada inokulasi 14 HST dan terendah pada inokulasi 21 HST. Total klorofil inokulasi 14 HST lebih rendah dan paling tinggi pada inokulasi 21 HST. Pada pertumbuhan tanaman diperoleh hasil yang tidak berbeda secara nyata pada variabel tinggi tanaman dan jumlah daun. Dari penelitian yang dilaksanakan dapat disimpulkan bahwa infeksi virus CMV berpengaruh terhadap perubahan tanaman cabai merah dan perlakuan beda waktu inokulasi tidak berpengaruh terhadap pertumbuhan tanaman.
English Abstract
Chili is one of the horticultural commodities that are cultivated by many farmers in Indonesia, because it has a high selling price. Chili needs continue to increase each year in line with the increasing number of population and the development of industries that require raw materials of chili. The cultivation of pepper plants can not be separated from the problem of decreasing the production of chillies caused by disease disorders. One of the diseases that attack chili is Cucumber Mosaic Virus (CMV). Virus-induced disease control is still very difficult, due to several factors, one of which is the high genetic diversity of CMV. The aim of this study was to determine the effect of CMV infection on the morphology and growth of red chili plants with a different treatment ratio of inoculation age.The research was conducted in green house and Plant Disease Laboratory belonging to Department of Hama and plant diseases, Faculty of Agriculture, University of Brawijaya, Malang. The experiment was conducted using Complete Randoised Design (CRD) method of treatment consisting of CMV 14 DAP, 21 DAP, 28 DAP, and negative control. Observation variables were incubation period, disease intensity, plant height, number of leaves, and total chlorophyll content. CMV infection affects morphological changes of plants that cause symptoms of mosaics, chlorosis, dwarfs, and malformations. During plant incubation period, 14 DAP inestablished treatment was the fastest and 21 DAP inoculation was no later. The highest disease intensity was 14 DAP inoculation and the lowest was inoculation of 21 DAP. The total chlorophyll inoculation of 14 DAP was lower and the highest was in the inoculation of 21 DAP. In the growth of plants obtained results that were not significantly different in the variable plant height and number of leaves. From the research carried out it can be concluded that CMV virus infection affects the red pepper plant. Treatment of different times of inoculation does not affect plant growth.
