Abstract

Sari. Paclobutrazol merupakan salah satu zat pengatur tumbuh yang dapat digunakan untuk memodifikasi pertumbuhan tanaman dengan cara mempertahankan keseimbangan pertumbuhan vegetatif dan generatif. Setiap genotipe tanaman akan menghasilkan respons yang berbeda terhadap pemberian paclobutrazol. Penelitian ini bertujuan untuk mengetahui interaksi antara konsentrasi paclobutrazol dengan dua klon ubi jalar serta mengetahui konsentrasi paclobutrazol yang terbaik untuk pertumbuhan dan hasil dua klon ubi jalar. Percobaan dilakukan pada bulan Februari sampai Juni 2017 di kebun Percobaan Ciparanje, Fakultas Pertanian Universitas Padjadjaran, Jatinangor, Kabupaten Sumedang, Jawa Barat pada ketinggian 750 m dpl. Jenis tanah tempat percobaan adalah Inceptisol, tipe curah hujan C menurut menurut klasifikasi Schmidt dan Ferguson bertipe C (agak basah). Percobaan menggunakan Rancangan Acak Kelompok (RAK) pola faktorial yang terdiri dari dua faktor dan diulang sebanyak empat kali. Faktor pertama yaitu klon ubi jalar (Awachy 1 dan Biang) dan faktor kedua yaitu konsentrasi paclobutrazol (0, 50, 100, 150 ppm). Hasil penelitian menunjukkan klon Biang menghasilkan jumlah ubi per tanaman yang lebih tinggi daripada klon Awachy 1. Konsentrasi paclobutrazol 50 ppm menghasilkan bobot ubi per tanaman yang lebih tinggi.

Kata Kunci: paclobutrazol, klon, ubi jalar.

Abstract. Paclobutrazol is one type of plant growth regulators that can be used to regulate plant growth with the aim of maintaining the balance of vegetative and generative growth. Each plant genotype would produce a different responses to paclobutrazol. The aimed of this study was to determine the interaction between the concentration of paclobutrazol and two sweet potato clones and to determined the best concentration of paclobutrazol for yield of two sweet potato clones. The experiment was conducted from February to June 2017 at Ciparanje Experimental Station, Faculty of Agriculture, Padjadjaran University, Jatinangor, Sumedang Regency, West Java on 750 m above sea level. Type of rainfall of the experimental area was classified as C type according to Schmidt and Ferguson. The experiment design used Factorial Randomized Block Design that consisted of two factors and repeated four times. The first factor was sweet potato clone (Biang and Awachy 1) and second factor was the concentration of paclobutrazol (0, 50, 100, 150 ppm). The results showed that the number of tubers in Biang produced higher than Awachy 1, and the treatment of paclobutrazol with concentration of 50 ppm had the best yield (weigth of tubers per plant).
