Abstract

This research aimed to study the effect of retardants concentration on the inhibition of apical shoots of rubber rootstock and analyze the relationship between the apical bud dormancy and grafting success relating to the influence of retardants. The study was conducted in the Teaching and Research Farm land, Faculty of Agriculture, Jambi University, Mendalo Darat Campus, Jambi Luar Kota District, Muaro Jambi Regency, on 35 m above sea level. Carbohydrate content analysis was carried out in the Basic and Integrated Laboratory of Jambi University. The research method used is Randomized Block Design with one factor this is retardan and three replications. The applied treatments are: ro = no treatment; r1 = paclobutrazol 500 ppm; r2 = paclobutrazol 750 ppm; r3 = paclobutrazol 1.000 ppm; r4 = paclobutrazol 1.250 ppm; r5 = paclobutrazol 1.500 ppm; r6 = cycocel 1.000 ppm; c7 = cycocel 2.000 ppm; c8 = cycocel 3.000 ppm. Overall, there are 9 treatments and 27 research unit. There are 12 plants on each research. The results showed that the application of paclobutrazol at concentrations of 1.500 ppm inhibits apical bud emergence on rubber seeds for 9 days and cycocel at a concentration of 3.000 ppm for 10 days. Inhibition of apical buds with paclobutrazol application to a concentration of 1,000 ppm can maintain the appearance of apical buds without inhibiting the growth and success of the grafting. Cycocel can slow the buds appear, without affecting the success of grafting.
