摘要：

In this paper comparative histological studies of embryo-like structures originating from callus cultures, and zygotic embryos originating from sexual seeds of Cuscuta trifolii are reported. The embryos of somatic cell and zygote origin showed similar morphological and anatomical features, such as a complete lack of cotyledon development and the differentiation of a developmentally unique root primordium specialised for water storage. Based on these findings, the regeneration of C. trifolii from callus cultures is shown to proceed along the pathway of somatic embryogenesis.
