Question

Epicormic branches are origited from which parts of the plants ?

• A. Leaves
• B. Fluted stem
• C. Buttessed stem
• D. Dormant buds on the stem

Hint:

Epicormic Branches = Shoots growing from suppressed/dormant buds on tree trunks when crown light exposure or stress breaks apical domince.

Answer 1

The Correct Option is D

Step 1: Understanding the Question:
The question asks to identify the structural origin of epicormic branches on tree trunks.

Step 2: Atomical Origin & Trigger Mechanisms:

• Epicormic Buds: Dormant, suppressed, or adventitious buds embedded deeply within the bark and cambial tissues along the main trunk or mature branches of woody trees.

• Sprouting Trigger: When the tree crown is damaged, heavily pruned, stressed by drought/disease, or suddenly exposed to intense sunlight (due to thinning), apical domince is broken.

• Epicormic Shoots: The dormant stem buds sprout to form leafy shoots known as epicormic branches (often called "water sprouts").

Step 3: Detailed Explation:

• Leaves, fluted stems, and buttresses are not the direct atomical point of bud initiation.

• Epicormic branching degrades timber quality because sprouting produces knots in the outer high-value clear wood.

• Proper forest canopy magement keeps stems shaded, suppressing dormant epicormic buds from sprouting.

Step 4: Fil Answer:
Epicormic branches origite from dormant buds on the stem. Therefore, option (D) is the correct answer.
