Abstract: The activity was carried out to determine grafting technique supporting high compatibility by studying aspects of the time and method of grafting and morphological, histological and biochemical changes during early process of graft formation. The results showed that the best grafting technique was the combination of the 2 months old rootstock with the top cleft or V-shaped grafting. The high grafting compatibility was expressed by the high glucose content of plant leaves and little gap of total sugar content between above and below graft union. Assessment histologically demonstrated that tissue regenerated compatibility and rejoint of vessels from wound tissues on graft union grew and developed as a normal composite plant.
