Abstract:
Graft union formation in mango (Mangifera indica L.) was studied using light microscopy. The initial wound response was resin secretion which contributed mainly to the initial adhesion of the graft partners. Early callus formation occurred mainly from the rootstock with cells produced in definite rows, often in fan-like array. Parenchyma cells at the cortex, pith, xylem and phloem rays were all involved in callus formation. The establishment of the cambial bridge between the stock and scion was followed by the formation of a protective layer, the periderm across the callus edges.
