ARTIFICIAL SEEDS

ARTIFICIAL SEEDS

31.      ARTIFICIAL SEEDS

There are many plants which neither have seeds nor produce a small number of seeds. To overcome this problem the concept of artificial seeds has become popular, where the somatic embryo is encapsulated in a suitable matrix composed of sodium alginate along with substances like mycorrhizae, herbicides, fungicides, insecticides. The technique involved in the production of artificial seeds is based on cellular totipotency and somatic embryogenesis. An artificial seed is a bead of gel contain a somatic embryo (or shoot bud) and the nutrients, growth regulators, the antibiotic etc need for the development of complete plantlets. 
Two methods for production:-
31.1.    Desiccates system:- The somatic embryos are first hardened to withstand desiccation and then are encapsulated.
31.2.    Hydrated system:- The beads become hardened as calcium alginate is formed, after about 20 minutes the artificial seeds are removed, washed with water and used for planting.
