The present invention relates to a method for inducing somatic embryos of Zinaria chinensis. The inflorescences of spaghetti algae are used as explants, and the surface-sterilized inflorescences are cut into 3-5mm long fragments and inoculated into somatic cells. On the embryo induction medium, conduct induction culture at 15-25°C, dark or weak light conditions, and transfer once every half month. After 15-25 days of culture, the tissue on the inflorescence can be seen to germinate, produce small protrusions, and gradually develop into somatic embryos. No callus phase was experienced during this period. The somatic embryo induction medium is a solid medium with MS and N6 medium as the base medium, supplemented with organic additives, carbon sources, plant hormones (auuxin, or auxin and cytokinin) and sea salt. The method of the present invention can directly induce the somatic embryos of Zinaria spp. It provided important technical support and laid the foundation for the success of seagrass tissue culture.
