Helmut Winterhager,Roland Kammel describing both embryogenesis pathways, comparing somatic and zygotic embryos and analyzing the role of the endosperm is presented. By taking zygotic embryos as the reference and learning from the situation in seeds, somatic embryogenesis can be improved and optimized in order to make use of the en

Helmut Winterhager,Roland Kammel. The induction of somatic embryogenesis in peach palm can be achieved by using different explant sources including zygotic embryos, immature inflorescences and thin cell layers from the young leaves and shoot meristems. The choice of a particular explant depends on whether clonal propagation is des

Helmut Winterhager,Roland Kammel, this volume). An advanced form of perennation is found in many apomictic species which produce embryos from unfertilized gametic or somatic cells. Like the zygotic embryos, the apomictic embryos develop within the seed and are protected and dispersed like natural seed. Apomictic embryos of all gen

r reports of haploid embryogenesis from cultured female gametophytic cells than from male gametophytic cells. This is related to the fact that microspores are more abundant, developmentally synchronized, uniform in size and easier to manipulate physically.
