Abstract

ABSTRAK
Budidaya tanaman buah naga di Indonesia sering mengalami kendala diantaranya
adalah tidak tersedianya bibit berkualitas saat tanam. Permasalahan tersebut dapat
diatasi dengan perbanyakan tanaman secara vegetatif dengan stek batang.
Keberhasilan stek dipengaruhi oleh berbagai faktor diantaranya zat pengatur
tumbuh. Penelitian ini bertujuan untuk mengetahui respon zat pengatur tumbuh
auksin dan menentukan konsentrasi zat pengatur tumbuh auksin yang paling baik
untuk meningkatkan pertumbuhan stek batang buah naga merah. Penelitian ini
dilaksanakan pada bulan Januari 2021 sampai dengan Maret 2021 di kebun Praktek
Wedomartani Fakultas Pertanian, Universitas Pembagunan Nasional “Veteran”
Yogyakarta. Penelitian ini menggunakan metode percobaan lingkungan di rumah
kaca dengan menggunakan Rancangan Acak Lengkap (RAL) satu faktor yaitu
pemberian konsentrasi zat pengatur tumbuh auksin yang terdiri dari 6 perlakuan,
yaitu Z1 (IBA 50 ppm), Z2 (IBA 100 ppm), Z3 (IBA 150 ppm), Z4 (NAA 50 ppm),
Z5 (NAA 100 ppm) dan Z6 (NAA 150 ppm). Data dianalisis keragamannya
menggunakan Uji Analisis of Varians (ANOVA) pada taraf 5% dan diuji lanjut
dengan menggunakan uji Duncan’s Multiple Range Test (DMRT) pada taraf 5%.
Hasil penelitian menunjukkan bahwa pemberian zat pengatur tumbuh auksin
terdapat pengaruh nyata pada panjang cabang umur 4 MST, panjang akar dan bobot
kering akar.

REGULATOR

ABSTRACT
Dragon fruit cultivation in Indonesia often experiences obstacles, including the
unavailability of quality seeds at planting. This problem can be overcome by
vegetative propagation of plants by stem cuttings. The success of cuttings is
influenced by various factors including growth regulators. This study aims to
determine the response of auxin growth regulators and determine the best
concentration of auxin growth regulators to increase the growth of red dragon fruit
stem cuttings. This research was conducted from January 2021 to March 2021 at
the Wedomartani Practical Garden, Faculty of Agriculture, National Development
University "Veteran" Yogyakarta. This study used an environmental experiment
method in a greenhouse using a completely randomized design (CRD) with one
factor, namely the administration of a concentration of auxin growth regulator
which consisted of 6 treatments, namely Z1 (IBA 50 ppm), Z2 (IBA 100 ppm), Z3
(IBA 150 ppm), Z4 (NAA 50 ppm), Z5 (NAA 100 ppm) and Z6 (NAA 150 ppm).
The data was analyzed for diversity using the Analysis of Variance Test (ANOVA)
at the 5% level and further tested using Duncan's Multiple Range Test (DMRT) at
the 5% level. The results showed that the administration of the growth regulator
auxin had a significant effect on branch length at 4 WAP, root length and root dry
weight.
