  • RESISTENSI GENOTIP ANGGREK PHALAENOPSIS TERHADAP PENYAKIT BUSUK LUNAK
  • No. Deskripsi Tahun Penulis Download
    1 Penyakit busuk lunak yang disebabkan oleh bakteri Erwinia carotovora merupakan salah satu penyakit penting pada tanaman phalaenopsis.Untuk mengevaluasi genotip-genotip yang resisten terhadap penyakit busuk lunak, suatu percobaan telah dilaksanakan di Balai Penelitian Tanaman Hias sejak bulan April sampai Desember 2002. Pada percobaan telah diuji sebanyak delapan genotif hibrida dan satu genotip pembanding. Hasil percobaan menunjukan bahwa genotip P.6505 dan P.503 merupakan genotip yang paling resisten terhadap penyakit busuk lunak. Teknik inokulasi dengan cara suntik dapat mempercepat proses skrining resistensi pada tanaman phalaenopsis. Penggunaan kultivar yang resisten akan dapat menekan penggunaan bakterisida. Kultivar yang resisten juga dapat dimanfaatkan sebagai sumber gen dalam rangka merakit baru tanaman phalaenopsis yang memiliki resistensi terhadap penyakit busuk lunak. Kata kunci; Phalaenopsis; Erwinia caroptovora ssp.carotovora; Resistensi. 2004 Handayati,W., Hanudin, dan S.Soejono
