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

The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Epicotyl (or stone) grafting is a propagation technique where scion sticks are grafted onto young, germinated rootstocks.
Establishing a successful vascular connection depends on callus formation at the graft interface.
Step 2: Detailed Explanation:
While the scion bud may sprout within 2 to 3 weeks, full structural healing at the graft union takes longer.
The complete union phase, where the cambial layers of rootstock and scion fuse to establish functional xylem and phloem, takes about 30 to 60 days.
After this healing period, the newly propagated plant is physiologically stable enough for field transplantation.
Step 3: Final Answer:
The healing union stage in epicotyl grafting extends from 30 to 60 days.
