Rapid propagation of some rare plants or plants with great economic value will prevent or rarely cause virus diseases of virus-free plants. Protection of plant germplasm resources and rescue of endangered plants. Haploid plants were obtained by anther and pollen culture, and the breeding cycle was shortened. To overcome the incompatibility of distant hybridization, tissue culture materials were used as plant bioreactors.

Tissue culture:

Plant tissue culture is a new asexual propagation technology based on the totipotency theory of plant cells in recent decades. Tissue culture of plants, also called in vitro culture in a broad sense, refers to the technology of separating tissues, organs or cells, protoplasts and so on. Inoculate them into the culture medium containing various nutrients and plant hormones under aseptic conditions to obtain regenerated complete plants or produce other products with economic value.
