Abstract

ABSTRAK Patogen tular benih didefinisikan sebagai setiap agen yang tertular oleh benih secara internal maupun eksternal yang berpotensi menyebabkan penyakit, Benih yang telah terinfeksi patogen tidak hanya menghambat pertumbuhan tanaman namun dapat pula menyebabkan keracunan, karena patogen mampu bertahan hidup pada habitatnya di tanah, gulma, dan sisa tanaman. Salah satu masyarakat Desa Lawang Agung pernah mengalami gagal panen, salah satu faktornya yaitu struktur benih padi terdapat bubuk berwarna putih dengan kondisi di dalam benih berwarna kuning, dan terdapat struktur bercak merah pada benih padi tersebut. Penelitian ini bertujuan untuk mengetahui jenis - jenis jamur patogen tular benih pada tiga varietas padi, dan untuk mengetahui persentase daya kecambah benih pada tiga varietas padi. Metode yang digunakan dalam pengambilan sampel yaitu teknik Random Sampling, satu varietas padi di ambil di tiga petani yang berbeda, Media yang digunakan dalam penelitian ini yaitu PDA, penelitian telah dilakukan pada bulan maret - mei 2023 di laboratorium tanaman satu Politeknik Negeri Lampung. Hasil penelitian pada jamur patogen tular benih pada tiga varieas padi di Desa Lawang Agung Kabupaten Oku Selatan ditemukan 7 genus jamur yaitu, Aspergillus, Rhizopus, Mucor, Alternaria, Fusarium, Rhizoctonia,dan Curvularia. Sedangkan hasil persentase daya kecambah pada tiga varietas yaitu : pada ketan hitam sampel satu 41%, sampel dua 81%,dan sampel tiga 84%, untuk ketan putih pada sampel satu 82%, sampel dua 79%, dan sampel tiga 86%. Dan pada ciherang sampel satu 96%, sampel dua 84%, dan sampel tiga 89%.

Seeds that have been infected with pathogens not only inhibit plant growth but can also cause poisoning, because pathogens are able to survive in their habitat in soil, weeds, and waste. plant. One of the people of Lawang Agung Village has experienced crop failure, one of the factors is that the structure of the rice seeds contains white powder with conditions inside the seeds which are yellow, and there is a structure of red spots on the rice seeds. This study aims to determine the types of seed-borne pathogenic fungi in three rice varieties, and to determine the percentage of seed germination in three rice varieties. The method used in sampling was the Random Sampling technique, one rice variety was taken from three different farmers. The media used in this study was PDA. The research was conducted in March - May 2023 in the Plant Laboratory of the Lampung State Polytechnic. The results of research on seed-borne pathogenic fungi on three varieties of rice in Lawang Agung Village, South Oku Regency found 7 genera of fungi namely, Aspergillus, Rhizopus, Mucor, Alternaria, Fusarium, Rhizoctonia, and Curvularia. While the percentage of germination power on three varieties, namely: on black sticky rice sample one 41%, sample two 81%, and sample three 84%, for white sticky rice on sample one 82%, sample two 79%, and sample three 86%. And in Ciherang sample one 96%, sample two 84%, and sample three 89%. Keywords: Inventory, Fungi, paddy, pathogen , Seed Borne
