Abstract

The purpose of this study was to determine the effect of interaction and the main application of various types of PGR and concentrations on the growth of stum grafting rubber plants. This study used a 2 factorial Completely Randomized Design. The first factor is PGR, consisting of 3 levels, namely: Ghost, Atonic and Hormax. The second factor was the ZPT concentration consisting of 4 levels, namely 2, 4, 6 and 8 ml/l in order to obtain 12 treatment combinations. Each treatment combination consisted of 3 replications, so that 36 experimental units (plots) were obtained. Parameters observed were age of shoot emergence, growth percentage, shoot length, number of leaves and root volume. Observational data were statistically analyzed and continued with the BNJ test at the 5% level. The results showed that the interaction of various types and concentrations of PGR was significantly related to the age of shoot emergence, shoot length and root volume. The best treatment combination was ZPT Hormax with a concentration of 8 ml/l (P3K4). The main effect of various types of PGR was significant on all parameters. The best treatment was ZPT Hormax (P3) . The main effect of PGR concentration was significant on all parameters. The best treatment was a concentration of 8 ml/l (K4).
