Pengaruh Macam Komposisi Media Tanam Dan Konsentrasi Zat Pengatur Tumbuh Rootone-F Terhadap Pertumbuhan Stek Kembang Kertas (Bougainvillea glabra) Dan Hasil Panen

Abstract

This research aims to see whether there is an interaction between the composition of the planting media and the
concentration of ZPT Rootone-F on the growth of Bougainvillea glabra cuttings. The results of this research can
provide information regarding the composition of the planting media and the concentration of ZPT Rootone-F
which can increase the growth of Bougainvillea glabra cuttings.
This experiment used a two-factor randomized block design (RAK) and was repeated twice. Factor 1 or more
precisely the composition of the planting medium (m) includes 4 levels: m1 = soil + sand + organic fertilizer (1:
1: 1), m2 = soil + sand + compost (2: 1: 1), m3 = soil + sand + compost (1: 2: 1) and m4 = soil + sand + compost
(1: 1: 2). The second factor is the use of different concentrations of Rootone-F, including 5 levels: f0 (0 g L-1
Water “Control”), f1 (10 g L-1 Water), f2 ( 20 g L-1 Water), f3 ( 300 g L-1 Water) and f4 (40 g L-1 Water).
Differences in media components and Rootone-F concentrations in Bougainvillea glabra cuttings had no effect on
the growth of Bougainvillea glabra cuttings. However, they produced different growth independently based on
different treatments.
Key words: Substances, cuttings, Rootone-F auxin concentration
