Comparison of somatic embryogenesis efficiency from in vitro explant sources of Ngoc Linh ginseng (Panax vietnamensis Ha et Grushv.)

Abstract

This study on the efficiency of embryogenesis from various explant sources of Ngoc Linh ginseng (Panax vietnamensis Ha et Grushv.) was conducted to select the appropriate materials and optimise embryogenesis in vitro. In this study, in vitro explants from leaf fragments, petioles, roots, and embryos (globular, heart-shaped, and cotyledon) were cultured on MS medium supplemented individually or in combination with 2,4-D (2,4-dichlorophenoxyacetic acid: 0.2, 0.5, and 0.7 mg/l) and TDZ (Thidiazuron: 0.1, 0.3, and 0.5 mg/l)...
