Kultur Embrio Jeruk Keprok (Citrus nobilis Lour) pada Media MS dengan Penambahan Kinetin

Abstract

Research on "Embryo Culture Keprok Orange (Citrus nobilis Lour.) on MS media with the addition of Kinetin" performed at the Laboratory of Plant Tissue Culture Department of Biology, Faculty of Mathematics and Natural Sciences University of Sumatra Utara. The research aims to identify the best concentration of kinetin to the growth of the embryo plantlets of keprok orange (Citrus nobilis Lour.) on MS medium. Research using Completely Randomized Design (CRD), non-factorial with kinetin treatment consists of 5 levels. In general, kinetin effect on all observed variables. Addition of kinetin significantly affect the number of shoots, weight of plantlets and root length. Concentration of 1 ppm (K1) produces the number of roots. The concentration of 2 ppm (K2) produces the number of shoots, weight of plantlet, shoot length and root length. Concentration of 3 ppm (K3) produces the number of leaves. At the root of microscopic observation showed that the first week of the root constituent tissue has been formed and there was no difference between all treatments kinetin.
