The Effect of Giving PGRs Rootone F on Cacao Cuttings (Theobroma Cacao. L) Wrapped in Molding Soil



Author(s): Ida Nursanti, Yuza Defitri, Asmara

Abstract:

Propagation by cuttings often experiences obstacles in root and shoot growth, because endogenous auxin in stem cuttings is in a concentration that is unable to affect root formation. One way to increase the role of auxin and encourage root growth is by administering plant growth regulators (PGRs) Rootone-F with the ends of the cuttings wrapped in molded soil. The study aims to study the effect of various PGRs concentrations on the growth of cacao plant cuttings wrapped in molded soil. The study was conducted in an experimental garden located in Batang Hari Regency, Jambi. The design used in this study used a Completely Randomized Design with one factor, the administration of PGRs Rootone-F with the tip of the cutting wrapped in mold soil with treatment levels R0 = 1 g Rootone-F, R1 = 1 g Rootone-F + Water 1cc cuttings-1, R2 = 1 g Rootone-F + Water 2cc cuttings-1, R3 = 1 g Rootone-F + Water 3cc cuttings-1, R4 = 1 g Rootone-F + Water 4cc cuttings-1. Observations; percentage of living cuttings, shoot length, number of leaves, number of primary roots. Data were analyzed statistically using analysis of variance, if the analysis of variance showed a significant effect, continued with the DNMRT test at the α level of 5%. Results of the study: The treatment of Rootone-F dosage gave a very significant effect on the percentage of living cuttings, shoot length, number of roots, number of leaves and root dry weight. Dosage 1 g Rootone-F + Water 4cc cuttings-1 showed better results than others.
