Abstract

This study aims to determine and study the effect of various Rootone F concentrations on the growth of the number and length of the roots of Stevia (Stevia rebaudiana) and to determine the most effective concentration of Rootone F to stimulate the growth of the roots of Stevia. The benefits of this research are as a way to multiply Stevia plants by utilizing synthetic growth regulators, namely Rootone F in the pressing process. This research was conducted on May 13th - July 10th, 2018 (60 days) and the method used was the experimental method using a Completely Randomized Design (CRD). The number of treatments is five kinds and five repetitions. The treatment of Rootone F concentration used was A = 0 ppm (control), B = 150 ppm, C = 300 ppm, D = 450 ppm and E = 600 ppm with a total sample of 25 polybag of Stevia plants. The results of observations on the growth of Stevia roots both in number and root length showed the highest value in treatment B, namely the concentration of 150 ppm. Although statistically it does not show significant differences for both the number and length of roots. From the observations of the data it can be concluded that the Rootone F hormone in a low concentration (150 ppm) stimulates root growth well compared to the greater concentration, it is caused because the hormone which is higher in concentration is an inhibitor of the growth of the roots of stevia plant cuttings
