Activity 8.1: Vegetative Propagation in Potato

Aim/Objective: To demonstrate the process of vegetative propagation in a potato through its "eyes."

Materials Required:

• A fresh potato with visible "eyes" (buds).
• A knife.
• A pot with soil.
• Water.

Procedure:

1. Observe a potato carefully. You will see some scars on its surface, which are the "eyes."
2. Cut the potato into small pieces, ensuring that each piece has at least one "eye."
3. Plant these pieces in a pot containing moist soil.
4. Water the soil regularly for a few days and observe the growth.

Observation:

• After a few days, green sprouts begin to emerge from the "eyes" of the potato pieces.
• Eventually, these sprouts grow into small potato plants with stems and leaves.

Explanation:

• Vegetative propagation is a form of asexual reproduction where a new plant grows from vegetative parts (roots, stems, or leaves) of the parent plant.
• The "eyes" of a potato are actually dormant buds (axillary buds) located at the nodes of the underground stem (tuber).
• When provided with favorable conditions like moisture, nutrients, and warmth, these buds become active and undergo rapid cell division (mitosis).
• The nutrients stored in the potato tuber provide the initial energy required for the growth of the young sprout until it develops its own leaves and can perform photosynthesis.

Conclusion:

• New plants can be successfully grown from the "eyes" (buds) of a potato tuber through vegetative propagation.
