dc.description.abstractResearch about the effect of addition coconut water and 2,4-d on the growth of young leaf arabica coffee (coffea arabica) plants through plant tissue culture techniques has been done at Plant Tissue Culture Laboratory of Faculty Mathematics and Science, University of Sumatera Utara. The research aimed to obtain medium with the suitable concentration of coconut water and 2,4-D for micro propagation of the coffee . The experiment was carried out using a completely randomized design with two factors and four replications. 15% coconut water treatment with a combination of 2,4-D 1 ppm provided most excellent influence on callus induction, fresh weight and dry weight callus. The combination of coconut water and 2,4-D with a concentration of 5% and 3 ppm and 15% and 3 ppm produced brown callus. While 14 other treatments produced white callus. All of the treatments produced friable callus.en_US
dc.description.abstractPenelitian tentang pengaruh penambahan air kelapa dan 2,4-D terhadap pertumbuhan daun muda tanaman kopi arabika (coffea arabica) melalui teknik kultur jaringan tanaman telah dilakukan di Laboratorium Kultur Jaringan Tumbuhan Departemen Biologi Fakultas Matematika dan Ilmu Pengetahuan Alam, Universitas Sumatera Utara. Tujuan penelitian ini untuk mendapatkan konsentrasi air kelapa dan 2,4-D yang tepat untuk perbanyakan mikro tanaman kopi arabika. Rancangan yang digunakan adalah rancangan acak lengkap (RAL) faktorial dua faktor dengan empat taraf air kelapa yaitu air kelapa 0; 5%; 10%; 15% dan empat taraf 2,4-D yaitu 0; 1 ppm; 2 ppm dan 3 ppm. Kombinasi air kelapa 15% dan 2,4-D 1 ppm memberikan pengaruh paling baik terhadap induksi kalus, berat basah dan berat kering kalus. Kombinasi air kelapa 5% dan 2,4-D 3 ppm menghasilkan kalus coklat, 14 perlakuan lainnya menghasilkan kalus putih. Seluruh perlakuan mengasilkan kalus remah.en_US
