Jurnal Agroekoteknologi Vol 4, No 1 (2016)
Publisher : Universitas Sumatera Utara

The aim of the research was to know effect of GA3 to rubber plant in micro shoot formation. The research was conducted at the rubber plant microcutting labortory PT Perkebunan Nusantara III Kebun Gunung Pamela, Tebing Tinggi, North Sumatera, Indonesia from April 2015 to Juli 2015. The Completely randomize design was used with two factors,i.e.:the addition of GA3 (GA3 0 mg/l; GA3 0.5 mg/l; GA3 1 mg/l; GA3 1.5 mg/l) and the immersion of nodes (GA3 0 mg/l; GA3 5 mg/l; GA3 10 mg/l; GA3 15 mg/l) with seven replications. The result showed that addition of 0.5 mg/l GA3 of significantly affected the percent of shoot emergence but no significantly different age of shoot emergence and immersion of nodes of 0 mg/l significantly affected the percent of shoot emergence but no significantly different age of shoot emergence and the interraction that addition of 0.5 mg/l GA3 and immersion of nodes significant affected the percent of shoot emergence on age of shoot emergence but no significantly different.Keywords : rubber, micro shoot, addition of GA3, immersion of nodesThe aim of the research was to know effect of GA3 to rubber plant in micro shoot formation.

Penelitian ini bertujuan untuk mengetahui respons pertumbuhan beberapa varietas sorgum pada tanah salin dengan pemberian giberelin. Penelitian ini dilaksanakan di Lahan Percobaan Fakultas Pertanian Universitas Sumatera Utara, Medan pada bulan Juli sampai Oktober 2015, menggunakan rancangan acak kelompok dengan dua faktor perlakuan yaitu varietas (Kawali, Numbu, Super 2) dan konsentrasi giberelin (0, 100 dan 200 ppm). Parameter yang diamati adalah tinggi tanaman, diameter batang, jumlah daun, umur berbunga, kehijauan daun dan berat malai per sampel. Hasil penelitian ini menunjukan bahwa perlakuan varietas berbeda nyata terhadap tinggi tanaman, jumlah daun, umur berbunga, bobot malai per sampel. Perlakuan pemberian giberelin dan interaksinya tidak berbeda nyata.
