Abstract
This study aimed to analyze the effect of regeneration on the growth of dragon fruit (Hilocereus undatus) explants at different planting positions and media composition in vitro. The data collection method used in this research is observing the research object. The design used was RAL (Completely Randomized Design). With different planting position treatments, namely the laying position and the upright planting position, then the composition of the media consisted of 9 treatments, namely: N0 (MS), N1 (BAP 2 ml/L), N2 (BAP 3 ml/L), N3 (NAA 2 ml/L), N4 (NAA 3 ml/L), N5 (BAP 2 ml/L+NAA 2 ml/L), N6 (BAP 2 ml/L+NAA 3 ml/L), N7 (BAP 3 ml /L, NAA 2 ml/L), N8 (BAP 3 ml/L, and NAA 3 ml/L). The results showed that the composition of the media made a difference to the growth of dragon fruit explants at each trying position. The media added with BAP 2 ml/L+NAA 3 ml/L in an upright position gave better results with an average shoot formation of 12.13 shoots per explant.
