In order to clarify the feasibility of regeneration and grafting reuse of rootstock and scion after
eggplant grafting，this paper took‘ Qiezhen No. 1’ as rootstock and‘ Yuanza 471’ as scion；studied the growth
and development process of rootstock and scion residue regeneration seedlings；and compared the healing and
growth indexes of residue grafting seedlings with initial grafting seedlings. The results showed that both the residue
stock of the rootstock and the scion could be healthily regenerated about 30 days after grafting. The plant stem
diameter could reach about 2.5 mm. Compared with the sowing seedlings，the rootstock and scion could shorten the
seedling raising time about 45 and 10 days，respectively. Compared with the initial grafting seedlings，the survival
rate，transporting capacity，resultant force and net growth of grafted seedlings in 35 days did not have significant
differences when grafted with rootstock and scion residue. And the cost of residue grafting seedlings was obviously
lower than that of initial grafting seedlings. Counting by every ten thousand grafted seedlings，the production cost
could be saved by 696.4 yuan. The grafted rootstock and scion residue could be regenerated and grafted again after
grafting. Thus，the economic benefits could be improved.
