Studi Sumber Stek Daun dengan Pemberian Rootone - F dan Benzil Amino Purin (BAP) Terhadap Pertumbuhan Tunas Stek Daun Kakao (Theobroma cacao)

Abstract

The low productivity of cocoa in Indonesia caused by the cocoa crop cultivation technologies that are still modest, and the use of cocoa planting material quality is not good. So we need to study the use of seeds that are relatively easy and practical is by way of leaf cuttings. Research on "Study Source Cuttings Leaves With Giving Rooton-F and Benzyl Amino Purine (BAP) on growth Tunas Leaf Cuttings Cocoa (Theobroma Cacao)" have conducted experiments in the garden of the Faculty of Agriculture, University Medan Area, Jalan Kolam No. 1 Medan Estate, from May to July 2014. The purpose of this study are: 1. Increase the percentage growth of the cocoa leaf cuttings. 2. Determine the influence of PGR results Rotoone-F and Benzyl Amino Purine (BAP) on the success of the cocoa leaf cuttings. This study uses a completely randomized design (CRD) factorial, 3 x 3 with three replications to obtain nine treatment combinations. The results showed that the growth of the cocoa leaf cuttings with the use of PGR at various concentrations no significant effect on the growth of leaf cuttings. Based on the results of this study concluded that: 1. Cocoa leaf cuttings has the potential to be developed as an alternative way of plant propagation. PGR granting Rootone-F on R1B3 treatment can give the highest percentage of survival reached 56.67%. 2. Granting of PGR Rootone-F and Benzyl Amino Purine (BAP) showed no real influence on the growth of callus on all treatments cocoa leaf cuttings.
