A technique of micropropagation is:
Protoplast fusion
Embryo rescue
Somatic hybridization
Somatic embryogenesis
An artificial method called micropropagation is used to create plants asexually from vegetative plant parts. A somatic cell can become an embryonic stem cell through a process known as somatic embryogenesis. This stem cell has the capacity to develop into an embryo, and subsequently, an entire plant. This procedure is performed in a controlled environment. Other forms of micropropagation include callus culture, where a callus is used to develop a complete plant, and meristem culture, where a meristem is used to create an entire plant.
The final answer is A technique of micropropagation is Somatic embryogenesis.
