Pertubuhan Eksplan Kotileon Jeruk Keprok ( Citrus Nobilis Lour.) dengan Kultur in Vitro pada Media MS (Murahige & Skoog) dengan BAP (Benzyl Amino Purin)

Abstract

Cotyledon culturing has been done in the Tissue Culture Laboratory, Department of Biology, Faculty of Mathematics and Science, University of North Sumatera. The tissue culturing was done using non-factorial Complete Random Design with the treatment using Benzylaminopurin (BAP) in 5 different concentrations, which were 0, 1, 2, 3, and 4 ppm respectively. Every treatment was repeated for six times and observed for four weeks. The result of the research showed that the success percentage of the cotyledon culturing were 75%. The BAP concentration of 4 ppm was the best concentration for the root length and bud length growth, 2 ppm was the best concentration for the bud quantity growth, 0 ppm (control) was the best for the root quantity growth and 1 ppm was the best for the planlet growth.
