Grafting is not successful in monocots but is successful in dicots because they have
-
Vascular bundles arranged in a ring
-
Cambiurti for secondary growth
-
Vessels with elements arranged end to end
-
Cork cambium
Grafting is not successful is monocots but is successful in dicots because monocots lack cambium tissue which forms secondary growth. The cambium possesses the ability to form secondary xylem and phloem. It is present in dicots. In case of grafting, it is very important that the plant should form primary and secondary tissue for its survival. So, it take place only in dicots.

Grafting
Plants with poor root system are propagated through grafting. Grafting is a horticultural technique whereby tissues of the plant are joined so as to continue their growth together. The two plants are selected, one with good roots called rootstock and another with good flowers, fruits, leaves or stem called scion. The scion contains the desired genes to be duplicated. The plants with poor roots but with the desired quality of other products are used as scion and grafted on plants with good mature roots.
