Question

Micropropagation is

• A. Raising of plants from a small tissue in culture
• B. Multiplication of small plants
• C. Propagation of small parts of organisms
• D. Indefinite maintenance of an organ or tissue

Answer 1

The correct option is A Raising of plants from a small tissue in culture

Micropropagation is the process of multiplication and maintenance of genetically modified or hybrid plant. The stock plants are cloned by the technique of micropropagation. It is also used to provide a sufficient number of plantlets for planting from a stock plant which does not produce seeds, or does not respond well to vegetative reproduction. The step of micropropagation includes:

1) The plant which needs to be propagated are chosed.

2) The plant part which has to be used as a explant is chosen. It can be the pollen, leaf, stem etc of the stock plant.

3) The explant is surface sterilized.

4) Culture the explant on a nutrient media.

5) After growth of root and shoot it undergoes hardening treatment where it is grown under temperature available on fields to prepare them for growth.

6) In the final stage of plant micropropagation, the plantlets are removed from the plant media and transferred to the soil.
