Abstract

Kelapa sawit di Indonesia dewasa ini merupakan  komoditas primadona. Perkecambahan benih kelapa sawit memerlukan waktu yang lama untuk berkecambah  yaitu 3 - 4 bulan karena adanya mekanisme dormansi pada benih. Lamanya waktu perkecambahan merupakan suatu  kendala bagi konsumen dan produsen benih. Umumnya perlakuan pematahan dormansi diberikan secara fisik, seperti skarifikasi mekanik dan kimiawi. Giberelin merupakan salah satu  zat pengatur tumbuh yang sering digunakan dalam memnbantu pematahan biji. Giberelin mengaktifkan enzim hidrolitik yang berperan dalam pemecahan cadangan makanan di dalam benih. Adapun tujuan dari penelitian ini adalah untuk mengetahui proses pematahan dormansi benih kelapa sawit (Elaeis guineensis Jacq.) dengan metode skarifikasi dan  konsentrasi giberelin yang sesuai dan mengetahuai adanya interaksi nyata dalam penggunaan  metode skarifikasi dan giberelin dalam membantu  mematahkan dormansi benih kelapa sawit (Elaeis guineensis Jacq.). Penelitian ini dilaksanakan mulai bulan Juni hingga september 2020 di Laboratorium Fisiologi Tumbuhan Universitas Sumatera Utara, Bahan yang digunakan yaitu biji kelapa sawit varietas Tenera yang diambil dari perkebunan  rakyat daerah Deli Serdang, Sumatera Utara. Penelitian ini menggunakan RAL (Rancangan Acak Lengkap) dengan 2 faktor yaitu letak buah pada tandan yaitu Apikal (A), Median (M) dan Basal (B)  dan Konsentrasi Giberelin yaitu G0 (0 ppm), G1 (200 ppm), G2 (300 ppm) dan G3 (400 ppm). Berdasarkan hasil yang diperoleh menunjukan bahwa posisi benih pada tandan dan konsentrasi giberelin yang diberikan memberikan pengaruh yang nyata terhadap daya berkecambah (DB) dimana pada perlakuan G3 menunjukan persentase benih berkecambah 36,67%  dan kontrol 6,67%. Rata – rata persentase embrio normal yang masih belum berkecambah terdapat pada kontrol (G0) hal ini dikarenakan hormon giberelin berpengaruh terhadap proses perkecambahan benih. Hasil penelitian juga menunjukkan persentase terkecil pada intensitas dormansi terdapat pada G3 yaitu 81,11% dan pada bagian apikal 77,5%. Hasil ini menunjukkan bahwa perlakuan skarifikasi dan giberelin yang sebelumnya juga diberikan perendaman dalam air panas efektif untuk pematahan dormansi benih kelapa sawit. Rata – rata PTM terdapat pada konsentrasi giberelin 400 ppm sebesar 26,67% dan terdapat pada bagian apikal, namun konsentrasi giberelin tidak berpengaruh nyata terhadap potensi tumbuh maksimum. Metode pematahan dormansi benih dengan skrafiksai dan perendaman dalam giberelin memberikan pengaruh yang nyata terhadap daya berkecambah, embrio normal dan intensitas dormansi namun tidak berpengaruh nyata terhadap potensi tumbuh maksimum. Pertumbuhan terbaik benih berasal bagian apikal dari tandan kelapa sawit.Kata Kunci : Pematahan Dormansi, Skarifikasi, Giberelin, Kelapa Sawit
