Abstract

Aphelenchoides besseyi merupakan salah satu nematoda parasit penting pada tanaman padi. Penelitian ini bertujuan mengetahui keberadaan A. besseyi pada benih padi varietas lokal dari tiga kecamatan di Kabupaten Samosir, yaitu Pangururan, Sianjur Mula-Mula, dan Palipi. Nematoda diekstrak dari 400 benih padi pada setiap varietas menggunakan metode modifikasi corong Baermann. Benih padi dipotong pada bagian hilum, direndam dalam air, dan diinkubasi dalam ruangan gelap selama 24 jam pada suhu 20 °C. Nematoda diidentifikasi berdasarkan ciri morfologi dan morfometri. Pengukuran morfometri A. besseyi dilakukan terhadap 70 nematoda betina dan 10 nematoda jantan. Nematoda A. besseyi ditemukan pada varietas ‘Si Serang’, ‘Saratus Ari’, ‘Si Pining’, dan ‘Si Bandung’ dengan populasi 5 sampai 13 individu per 10 g atau 400 butir benih padi. Nematoda A. besseyi berhasil diidentifikasi berdasarkan ciri-ciri morfologi, yaitu tubuh ramping, bibir set off, stilet tipis, median bulbus berukuran besar, dan terdapat mucro berbentuk bintang pada ujung ekor. Nematoda jantan memiliki ujung ekor melengkung dengan spikula berbentuk seperti duri mawar. Ukuran tubuh nematoda pucuk putih asal varietas padi lokal Samosir lebih kecil dibandingkan ukuran A. besseyi yang telah dilaporkan sebelumnya.

Abstract

Rice (Oryza sativa L.) is the main staple crop in Indonesia. This study aims to analyze the nematode communities found in irrigated and rainfed lowland rice cultivation areas and to identify nematodes associated with rice plants in Sukabumi Regency, West Java. Nematodes were extracted from soil using the centrifugal flotation method, root samples using a mist chamber, and leaf and seed samples using a modified Baermann funnel method. Nematodes were identified based on morphological characteristics. Nematode community analysis was conducted by calculating absolute population, diversity index, evenness, and dominance. Nematodes found in both irrigated and rainfed fields exhibited low diversity, low evenness, and high dominance. The nematodes in irrigated rice fields included genus Helicotylenchus, Rhabditis, Meloidogyne, Hirschmanniella, Tylenchorhynchus, Pratylenchus, and Aphelenchoides. Nematodes found in rainfed rice fields included Meloidogyne, Hirschmanniella, and Criconemella. Meloidogyne spp. was among the dominant nematodes in root and soil samples across various rice cultivation types and locations.
