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.
True
Hydrated synthetic seeds are produced by encapsulating the somatic embryos or somatic propagules in hydrogel capsules.
True
Dessicated synthetic seeds are formed by mixing equal volume of embryo suspension and 5% of polyethylene oxide, which subsequently dried to form poly-embryonic dessicated seeds.
True
One of the applications of synthetic seeds is the production of large number of identical embryos.
