| The structure of shoot apex in zygotic and somatic embryos of Daucus carota L. cv. Hongshim was observed by using SEM and longitudinal sections. Shoot apex of zygotic embryo was of an inverted boat shape, and these of two, three and four cotyledon somatic embryos were of an inverted boat shape, a pyramid shape and a convex diamond shape, respectively. In zygotic embryo shoot apex is consisted of small cells which are arranged in layers (tunica) and show corpus in central region. In somatic embryos shoot apices are consisted of somewhat large cells which are arranged in irregularly or slight regularly. |
