Question

Compare the statements I and II and choose correct option.
Statement (I) Auxin promotes apical dominance by suppressing the activity of lateral buds.
Statement (II) In moriculture, periodic prunning of shoot tips is done to make mulberry plants bushy.
Choose the correct options.

• A. I is false, but II is true
• B. II is false, but I is true
• C. Both I and II are true
• D. Both I and II are false

Answer 1

Answer: (C)

Both I and II are true

• Auxin is a plant growth hormone. This hormone is responsible for the growth and elongation of the shoot.
• There is apical dominance observed in the presence of auxin. This results in the growth of the central stem which is dominant and suppresses the growth of the lateral buds.
• The auxins are produced at the tips. The pruning of the tips is done where the branches are cut periodically in moriculture.
• This allows the lateral buds to grow and form branches. This helps to make the plant bushy.

Thus, the correct answer is option C.
