Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh jenis media tumbuh aklimatisasi dan jenis pupuk daun terhadap pertumbuhan pada proses aklimitasiasi anggrek Dendrobium sp. Penelitian ini dilaksanakan di Laboratorium Pemuliaan Tanaman, Fakultas Pertanian, Universitas Sumatera Utara, Medan yang dimulai dari bulan Januari sampai dengan Maret 2009. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan dua faktor. Faktor pertama adalah jenis media tumbuh aklimatisasi (arang sekam, cocopeat, dan campuran antara arang sekam dan cocopeat). Faktor yang kedua adalah jenis pupuk daun (pupuk majemuk foliar I dan pupuk majemuk foliar II). Parameter yang diamati adalah persentase hidup, pertambahan tinggi planlet, pertambahan diameter batang, pertambahan jumlah daun, pertambahan berat total, saat muncul tunas, jumlah tunas, berat akar, volume akar dan jumlah klorofil daun. Hasil penelitian menunjukkan bahwa interaksi jenis media tumbuh aklimatisasi dengan jenis pupuk daun berpengaruh nyata terhadap parameter saat muncul tunas dan jumlah tunas. Kata kunci: acclimitazation, orchid, Dendrobium sp

Abstract

The research was carried out at public land Desa Namo Gajah, Kecamatan Medan Tuntungan(±25 m dpl) on April to November 2015. The research used factorial Randomized Block Design (RBD) with two factors and three replications.The first factor was sweet potato varietieswith 3 kinds (Antin-1; Beta-1; and Sari)and the second factorwas rice straw compost with 4 levels(0; 5; 10; and 15 ton/ha). Data were analized with Analysis of Variance and continued with Duncan’s Multiple Range Test (DMRT). The variables observed weight biomass of plant, tuber weight per plot, and harvest index. The result of research showed that the best interaction of sweet potato varieties and rice straw compost was combination of Sari and rice straw compost 2 kg on weight biomass, tuber weight per plot, and harvest index.

Abstract

The aim of the research was to determine the best paclobutrazol treatment to obtain superior quality seed potato cultivars. The research was conducted at the Tissue Culture Laboratory of Horticulture Technical Centre Service Unit, Gedung Johor, Medan, North Sumatra, Indonesia from January 2020 to March 2020. The complete randomized design with a single factor, 4 treatments, and 6 replications was used in this research. The results showed that the concentration of paclobutrazol affected the number of leaves, the shoots length, the number of shots, the number of nodes, the number of internodes, the stem diameter, and the percentage of roots formed but not significantly affected the number of roots. The M2 treatment, MS + 9 ppm paclobutrazol, showed the best treatment with an average plantlet performance value of 7.33 and the plantlets showed the compact morphology with larger stem diameter and smaller thick dark green leaves.
