Abstract

ABSTRACT Indonesia is the world's second largest producer of natural rubber. However, low quality of seedlings became the main problem of Indonesian smallholder rubber plantations. So the main improvement that can be done is to use budded stump derived from superior clones. One of the superior clones recommended namely IRR 112 that was cloned from hybrid offspring of IAN 873 and RRIC 110 latex rubber plant and wood producers. The budded stump is lightweight and so easy to transport but its percentage of deaths of seedlings are considered high. To reduce the percentage of death of budded stump, researcher used polybags to plant it and also provided it with growth regulators (ZPT) to improve the growth of grafting. This research was conducted in Kenali Asam Bawah, Kotabaru, Jambi City for three months from November 2016 to January 2017. This research used one-factor randomized block design consisting of 6 treatments i.e. without Rootone-F (p0), adding 500 ppm of Rootone- F (p1), adding 1000 ppm of Rootone-F (p2), adding 1500 ppm of Rootone-F (p3), adding 2000 ppm Rootone-F (p4) and adding 2500 ppm Rootone-F (p5) rearing 4 replicates consisting of 10 plants to see the effect of each treatments. Data were analyzed with Duncan Multiple Range Test (DMRT) Test at 5% level. As the result, Rootone-F 2,500 ppm was the best concentration indicated by the highest number on each parameters, 25.63 cm bud length, 6.67 mm bud diameter, lateral root quantity 7, dried-canopy weight of 51.87 g, dried-root weight 41.53 g and time of formation of leaves umbrella showed 26 days. Keywords: Budded stump, IRR 112 clone, Rootone-F
