Questions and Answers
Synthetic seeds are defined as artificially encapsulated somatic embryos, shoot buds, cell aggregates or any other tissue that can be used for sowing a seed and that possess the ability to convert into a plant under in vitro or ex vitro conditions and that retain this potential also after storage.
