Question

In case of epicotyl grafting in mango, healing union stage extends from

• A. 30-60 days
• B. 60-120 days
• C. 120-180 days
• D. 180-200 days

Hint:

Graft healing in woody plants like mango is a gradual process. A strong union needs not just callus, but also new, functional vascular connections between scion and rootstock. This typically takes several months for the plant to be considered well-established.

Answer 1

The Correct Option is C

Step 1: After epicotyl grafting, the joint first forms a callus bridge, then develops vascular connections between scion and rootstock.
Step 2: A partial union within 60-120 days is still fragile and not fully field-ready.
Step 3: Nursery practice shows the union becomes strong and well-established within about 120-180 days, after which the graft is considered healed.
Step 4: The correct answer is 120-180 days.
