Question

When scion and stock are combined during
grafting, their cambium should be in close
contact. Why?​

Answer 1

Explanation:

Compatibility of scion and stock: Because grafting involves the joining of vascular tissues between the scion and rootstock, plants lacking vascular cambium, such as monocots, cannot normally be grafted. As a general rule, the closer two plants are genetically, the more likely the graft union will form.
