Somatic embryogenesis of two new Panax ginseng cultivars, Yun-Poong and Chun-Poong

Somatic embryogenesis of two new Panax ginseng cultivars, Yun-Poong and Chun-Poong Somatic embryogenesis from single cells is important for normal plant regeneration of ginseng. Cotyledon explants from zygotic embryos of two new ginseng cultivars, Chun-Poong and Yun-Poong, produced somatic embryos on Murashige and Skoog (MS) basal medium and MS medium containing growth regulators. The highest frequency of single somatic embryo formation was obtained when cotyledon explants were excised from premature (cultured for 1 day) zygotic embryos (about 6 mm in length) of both cvs. Chun-Poong and Yun-Poong and then cultured on MS medium supplemented with 7% sucrose. The frequency of single somatic embryo formation was strongly enhanced when Chun-Poong cotyledons were subjected to plasmolysis with 0.1–0.5 M sucrose for 24 h and Yun-Poong cotyledons to plasmolysis with 1.0 M sucrose for 24 h and then cultured on MS medium with 2,4-D. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Plant Physiology Springer Journals

Abstract

Somatic embryogenesis from single cells is important for normal plant regeneration of ginseng. Cotyledon explants from zygotic embryos of two new ginseng cultivars, Chun-Poong and Yun-Poong, produced somatic embryos on Murashige and Skoog (MS) basal medium and MS medium containing growth regulators. The highest frequency of single somatic embryo formation was obtained when cotyledon explants were excised from premature (cultured for 1 day) zygotic embryos (about 6 mm in length) of both cvs. Chun-Poong and Yun-Poong and then cultured on MS medium supplemented with 7% sucrose. The frequency of single somatic embryo formation was strongly enhanced when Chun-Poong cotyledons were subjected to plasmolysis with 0.1–0.5 M sucrose for 24 h and Yun-Poong cotyledons to plasmolysis with 1.0 M sucrose for 24 h and then cultured on MS medium with 2,4-D.
