Question

The process of removing the terminal bud to promote lateral branching is called ______.

• A. Pruning
• B. Pinching
• C. Grafting
• D. Layering

Hint:

Remember: Pinching = Remove tip → More branches.

Answer 1

The Correct Option is B

Concept: Plant growth can be manipulated by removing certain parts to control shape and branching. The terminal bud exerts apical dominance, suppressing lateral buds.
Step 1: Understanding apical dominance.
The terminal (apical) bud produces auxin, which inhibits the growth of lateral buds.
Step 2: Effect of removing terminal bud.
When the terminal bud is removed, apical dominance is broken, allowing lateral buds to grow.
Step 3: Identifying the process.
The specific removal of the terminal bud is known as pinching.
Step 4: Evaluating the options.

• Pruning $\rightarrow$ General removal of plant parts (incorrect)
• Pinching $\rightarrow$ Removal of terminal bud to promote branching (correct)
• Grafting $\rightarrow$ Joining plant parts (incorrect)
• Layering $\rightarrow$ Vegetative propagation method (incorrect)

Step 5: Additional insight.
Pinching is commonly practiced in ornamental plants and crops to encourage bushy growth and increase flower or fruit production.
Step 6: Conclusion.
Thus, the process is called pinching.
