ABSTRACT
This research aimed to determine the effect of NAA and Kinetin on the growth of explants dragon fruit (Hylocereus costaricensis). This research was conducted at the Laboratory of Biology Education University of Riau and Laboratory Biotechnology of Riau Islamic University from May to August 2012, using a completely randomized design of 3 x 3 factorial with four replications. The first factor (N) is the NAA consists of 3 level: 0 ppm, 0.2 ppm, 0.4 ppm. The second factor (K) is the Kinetin consist of 3 level: 0 ppm, 3 ppm, 4 ppm. Parameters measured were percentage grows, the amount of buds and amount of roots. The data were analyzed using ANAVA and tested further by DMRT at 5% level. The results of this research showed of NAA and Kinetin significantly affect the growth of explants Dragon Fruit. The percentage of explants grown 100% all treatments except treatment N0 K4, N0,2 K0 dan N0,2 K3. Highest amount of buds in treatment N0,4K3 is 2.25 buds and the amount of roots the best treatment of N0,4K4 is 5.25 roots. Based on the results of the research treatment N0, 4 K4 is the best treatment.
