Write a short note on Micro propagation.
Micro propagation: This is the propagation of plants involving cell and tissue culture. If vegetative propagation is not possible in a crop, then buds, shoot apex or any other part of the plant can be used as explant for micropropagation.
- The explants are treated with sterilisation chemicals to prevent microbial growth, and then cultured in a particular nutrient medium.
- Cells grow and divide to form a cell mass called callus Some growth regulators (Plant hormones) are added.
- The callus differentiates into plant parts looking like plant (plantlet). After 4-6 weeks the plantlets transferred to the soil
