Abstract:
The purpose of the experiment was to determine the role that naphthalene acetic acid (NAA) played in the effective root induction of dragon fruit explants. Six levels of naphthalene acetic acid (NAA) were applied for root multiplication of dragon fruit explants, which were 0, 0.1, 0.2, 0.3, 0.4, and 0.5 μM. The treatments were executed in the laboratory with four replications with ten samples each and laid out in completely randomized design (CRD). Results of the experiment showed that the earliest days to induce the first root (11.25 days) were observed in 0.3 μM NAA-containing medium. 100% root formation was recorded from 0.3 μM NAA containing medium from explants. The maximum root number per plantlet (4) was produced in the medium supplemented with 0.3 μM NAA. The explants grown in the medium containing 0.3 and 0.4 μM NAA produced the longest shoots at 9.35 cm and 8.25 cm, respectively. In 0.3 μM NAA-containing media, the maximum fresh weight of plantlets (0.60 g) was obtained.
