Abstract


Penyakit mosaik tercatat sebagai salah satu faktor pembatas dalam produksi tanaman nilam (Pogostemon cablin). Penelitian ini dilakukan untuk mengukur pengaruh infeksi virus penyebab penyakit mosaik terhadap produksi dan kadar minyak tanaman nilam. Bahan yang digunakan dalam penelitian ini adalah tiga varietas unggul tanaman nilam yaitu Sidikalang, Lhokseumawe dan Tapak Tuan. Infeksi Potyvirus berhasil dideteksi pada varietas Tapak Tuan dan Lhok-seumawe berdasarkan hasil metode ELISA. Pengukuran berat terna basah, terna kering, kadar minyak dan kadar patchouli alcohol (PA) yang dilakukan pada tanaman berumur enam bulan menunjukkan terjadinya penurunan produksi dan kadar minyak. Penurunan tertinggi berat terna basah, terna kering, kadar minyak dan kadar PA berturut-turut dapat mencapai 34,65, 40,42, 9,09 dan 5,06%.
