One is the use of grafting seedlings. Effort to get success grafting eye stum high bed that is seeking a suitable environment so that it can support the growth of the rubber grafting. Growth grafting eye stum good sleep obtained when the medium used has good quality in terms of physical, chemical and biological. To accelerate the growth of seedlings can be grafted plant growth regulators. Research conducted experiments consisting of 4 treatments arranged in completely randomized design (CRD) consisting of 4 treatments, namely: R0 (without giving PGR), R1 (giving coconut water), R2 (granting IBA), R3 (giving gibberellins). Each treatment was repeated 4 times, with each unit consisting of 3 seeds experiment, so the total number of seeds was prepared as many as 48 seeds. The data were analyzed by Analysis of Variance (ANOVA) and further tested by the Least Significant Difference (LSD) at the 5% level. The meter is observed when the buds appear, shoot length, shoot diameter, number of leaves (strands), root length. Provision of plant growth regulators significant effect on the growth of the eye stum sleep. Provision of plant growth regulators IBA with the recommended dose (1,500 ppm) gave the best growth of the eye stum rubber bed.
