Abstract: Roots of rubber tree were collected and used to graft onto young budded plants at the nursery under different conditions such as rootgrafting materials,methods and time,and their survival rates were compared.The root graftings showed that the in vitro root graftings had a higher success rate than the in situ root graftings.The root-graftings had a higher success rate when the top-leaf whorl of the interim plants was at the stable leaf stage and the bud emerging stage of phenophase,and they had a high success rate in the rapid growth season from April to August and when the diameter and length of the root sections increased in a given range. The root sections 4 mm thick in diameter and 25 cm to 45 cm long were optimal for in vitro root grafting.
