      Abstract
      Nematoda parasit tumbuhan merupakan salah satu faktor kendala dalam budi daya seledri (Apium graveolens L.). Penelitian ini bertujuan mengidentifikasi dan menentukan dominansi genus fitonematoda melalui analisis kuantitatif terhadap nilai populasi absolut dan frekuensi absolut. Sampel diambil secara purposif dari lahan polikultur seledri di Kecamatan Pacet. Ekstraksi nematoda dilakukan menggunakan metode sentrifugasi-flotasi dan pengabutan untuk sampel tanah dan akar. Identifikasi morfologi didasarkan pada karakteristik nematoda juvenil dan dewasa, dengan pola perineal pada nematoda betina dewasa untuk genus Meloidogyne. Empat genus fitonematoda berhasil diidentifikasi, yaitu Meloidogyne, Rotylenchulus, Tylenchus, dan Criconemoides. Genus Meloidogyne merupakan takson dominan dengan nilai prominensi (NP) tertinggi pada jaringan akar (1784,44) dan tanah (478,33) tanaman yang menunjukkan gejala penyakit. Dominansi ini diduga disebabkan oleh koeksistensi dua spesies polifagus, yaitu M. incognita dan M. arenaria. Sementara itu, integrasi polikultur dengan famili Alliaceae (bawang daun) mampu menekan populasi nematoda. Plant-parasitic nematodes are one of the limiting factors in celery (Apium graveolens L.) cultivation. This study was aimed to identify and determine the dominance of phytonematode genera through quantitative analysis of population counts and absolute frequencies. Samples were taken purposively from celery polyculture fields in Pacet District. Nematode extraction was performed using the mist chamber and centrifugation-flotation methods for root and soil samples. Morphological identification was based on juvenile and adult characteristics, with the perineal patterns of adult females for Meloidogyne. Four phytonematode genera were successfully identified, namely Meloidogyne, Rotylenchulus, Tylenchus, and Criconemoides. The genus Meloidogyne was the dominant taxon with the highest prominence value (PV) in root tissue (1784,44) and soil (478,33) of symptomatic plants. This dominance is believed to be caused by the coexistence of two polyphagous species, M. incognita and M. arenaria. Meanwhile, the integration of polyculture with the Alliaceae family (scallions) was able to suppress the nematode population.
