Behaviour of hog plum grafted over umbu in Pacajus region in Ceará state, Brazil

Spondias mombin is an Anacardeaceae fruit tree family, widely exploited with drupe yellow sour-sweet taste, highly contents of carotenoid, sugars and vitamins A and C. It is know under several regional names such as hog plum or yellow mombin and is commonly used as a human food source. The main constraints of cropping this species are the lack of uniform recomended clonal genotype and the high height of the plant. The Spondias mombin can be grafted over S. tuberosa showing compatibility and good interaction between both grafting parts. But it doesn't have interference on top plant growth. The top plant growth is similar to that observed by seed propagated plant, thus it tends toward growing by one single trunk and high height. Nevertheless, the control of tree grow and shaping its canopy into exploitation models suitable for intensive cropping still needs further studies as much as to pruning practices and time.
