-, Nurhalimah (2019) Ketahanan Tanaman Cabai Rawit (Capsicum frutescens L.) Terhadap Penyakit Layu Fusarium Yang Ditanam pada Media Pasir Kuarsa AMB-P0K Dengan Inokulasi Mikoriza. Sarjana thesis, Universitas Brawijaya.
Abstract
Penyakit merupakan salah satu hambatan utama pada budidaya tanaman cabai rawit. Penyakit yang sering terdapat pada tanaman cabai adalah penyakit layu fusarium yang disebabkan oleh Fusarium oxysporum f.sp. capsici yang dapat menimbulkan kerusakan hingga 50%. Tingkat ketahanan terhadap F. oxysporum dapat dikategorikam agak tahan sampai sangat tahan. Informasi yang tepat mengenai penggunaan media pasir serta pemberian mikoriza yang diperlukan terhadap pertumbuhan tanaman serta ketahanannya terhadap intensitas serangan penyakit khususnya jamur pada tanaman sangat diperlukan. Penelitian bertujuan untuk mengetahui ketahanan tanaman cabai rawit terhadap penyakit layu fusarium yang disebabkan patogen Fusarium oxysporum f.sp. capsici yang ditanam pada media pasir kuarsa AMB-POK melalui inokulasi mikoriza. Penelitian dilaksanakan di Rumah kaca (Greenhouse) Jurusan Biologi, Fakultas Saintek, Universitas Islam Maulana Malik Ibrahim Malang, Laboratorium Penyakit Tumbuhan Jurusan Hama dan Penyakit Tumbuhan, Fakultas Pertanian Universitas Brawijaya Malang dan Laboratorium Farmasi, Universitas Ma chung Malang selama 5 bulan dari bulan Januari – Mei 2019. Tahapan penelitian yaitu penanaman tanaman uji dan inokulasi mikoriza, inokulasi jamur patogen Fusarium oxysporum f.sp. capsici, dan pemeliharaan tanaman. Variabel yang diamati yaitu waktu muncul gejala penyakit, keparahan penyakit, tinggi tanaman, jumlah daun, jumlah buah, dan kadar saponin. Berdasarkan hasil penelitian pada tanaman cabai rawit terhadap ketahanan yang disebakan oleh penyakit layu fusarium dengan pemberian dosis masing-masing sebanyak 5, 10, dan 15 g. Hasil pengamatan menunjukan bahwa pemberian mikoriza sebesar 15 g pada media tanam AMB-P0K menunjukkan hasil yang baik dibandingkan dengan kontrol. Terlihat pada hasil tinggi tanaman, jumlah daun, dan jumlah buah tanaman cabai rawit serta waktu muncul gejala penyakit dan keparahan penyakit akibat serangan penyakit layu fusarium. Hal tersebut diketahui berdasarkan pada hasil menurunnya keparahan penyakit pada perlakuan pemberian mikoriza 15 g sebesar (4,56 %) yang menunjukkan bahwa tingkat ketahanan tanaman meningkat dan berdampak pada tinggi tanaman, jumlah daun, dan jumlah buah. Faktor lingkungan yaitu suhu, kelembaban tanah, pH, nutrisi N, P, dan K mempengaruhi perkembangan penyakit layu fusarium.
English Abstract
Disease is one of the main obstacles in the cultivation of cayenne. A common disease in chili plants is fusarium wilt caused by Fusarium oxysporum f.sp. capsici which can cause damage up to 50%. The level of resistance to F. oxysporum can be categorized rather resistant to very resistant. Appropriate information about the use of sand media and the administration of mycorrhizal which is needed for plant growth and its resistance to the intensity of disease attacks, especially fungi in plants is very necessary. The study aimed to determine the resistance of cayenne pepper to fusarium wilt caused by the pathogen Fusarium oxysporum f.sp. capsici which was planted on quartz sand media AMB-POK through mycorrhizal inoculation The research was conducted in the Greenhouse of the Biology Department, Faculty of Science and Technology, Maulana Malik Ibrahim Malang Islamic University, Laboratory of Plant Diseases Department of Plant Pests and Diseases, Faculty of Agriculture, Brawijaya University Malang and Pharmacy Laboratory, Ma Chung Malang University for 5 months from January - May 2019. The research stages were planting of test plants and mycorrhizal inoculation, inoculation of pathogenic fungi Fusarium oxysporum f.sp. capsici, and plant maintenance. The variables observed were the time of symptoms of illness, severity of disease, plant height, number of leaves, number of fruits, and saponin levels. Based on the results of research on cayenne pepper to the resistance caused by fusarium wilt by giving doses of 5, 10 and 15 g respectively. The results showed that administration of mycorrhizal at 15 g in AMB-P0K growing media showed good results compared to controls. It can be seen in the results of plant height, number of leaves, and the number of cayenne fruit and the time the symptoms appeared and the severity of the disease due to fusarium wilt. It is known based on the results of the decrease in severity of the disease in the treatment of administration of 15 g mycorrhizal as big as (4.56%) which indicates that the resistance level of the plant increases and impacts on plant height, number of leaves, and number of fruits. Environmental factors namely temperature, soil moisture, pH, nutrients N, P, and K affect the development of fusarium wilt.
