Micropropagation Steps Sequence Explained

Micropropagation is a vital technique for rapidly multiplying plants using tissue culture methods under sterile conditions. Achieving successful plant propagation requires following a precise sequence of steps.

Correct Sequence for Plant Micropropagation

The procedure involves preparing the plant material, ensuring its sterility, and then facilitating its growth in a controlled environment. The correct order of the given steps is:

1. A. Collection of explant: This is the initial step where the plant part (like a shoot tip or leaf segment) is carefully selected and collected from the parent plant.
2. E. Surface sterilization: The collected explant is then thoroughly washed and treated with sterilizing agents to eliminate any microorganisms present on its surface.
3. C. Adding of teapol to explant and sterilant: Following surface sterilization, this step involves applying specific treatments, potentially rinsing agents or components of a sterilant solution, to the explant before it is placed on the nutrient medium.
4. B. Inoculation: The sterilized and treated explant is transferred onto a sterile nutrient medium within a culture container.
5. D. Subculturing: As the tissue grows, it is periodically transferred to fresh nutrient medium to provide necessary nutrients and promote further development and multiplication.

Key Stages Summary

The sequence ensures that the plant material is viable and free from contamination. The progression from explant collection (A) through sterilization (E), specialized treatment (C), inoculation onto medium (B), and subsequent maintenance via subculturing (D) is critical for effective micropropagation.
