Study of Ms Media With Addition Of Auxins And Cytokinin on Growth and Development of Arr (Arenga Pinnata (Wurmb) Merr.) Culture.

Abstract

Aren has an important role as a biofuel producer, so research is needed for the development of this plant. This research has been carried out in the Tissue Culture Laboratory of the Department of Agrotechnology, Faculty of Agriculture, Muhammadiyah University, North Sumatra, from October 2017 to September 2018. This study aims to obtain a combination of concentrations of growth regulators of curcumin and cytokines which are best for increasing plant population in vitro culture. , as well as to produce large quantities of quality plantlets in a relatively short time. Experiments in the form of a Completely Randomized Design (CRD) were repeated 3 times with 5 samples of each treatment to obtain 105 units of experimentation. The first series experiment was the regeneration stage, shoot tip results were cultured on WPM media with a concentration of 0.25 ppm + 1.0 ppm Kinetin which was used as explants. Furthermore, the shoots were regenerated in the WPM medium with the treatment of concentration of growth regulators of auxin and cytokinin which consisted of 7 treatment levels, namely (E0) 0.00 ppm NAA + 0.00 ppm BAP, (El) 0.00 ppm NAA + 0.25 ppm BAP, (E2) 0.50 ppm NAA + 0.00 ppm BAP, (E3) 0.50 ppm NAA + 0.50 ppm BAP, (E4) 0.00 ppm NAA + 0.75 ppm BAP, (E5) 0.50 ppm NAA + 0.75 ppm BAP, (E6) 1.00 ppm NAA + 1.00 ppm BAP. From the observed variables, the percentage of live explants and percentage of explants forming callus the best results were found in a combination of 1.00 ppm NAA + 1.00 ppm BAP (E6) concentration.
