摘　　要：为了明确茄子嫁接后砧木、接穗残株的再生进程及再次嫁接利用的可行性,以茄砧1号、园杂471为砧木和接穗品种,研究砧木、接穗残株再生苗的生长发育进程,并比较残株再生苗嫁接与初次嫁接苗的愈合情况和生长指标。结果表明:茄子嫁接后砧木残株扦插再生、接穗残株腋芽再生30 d左右均可形成健壮的幼苗,植株茎粗可达2.5 mm左右,与播种育苗相比,砧木、接穗分别缩短育苗时间约45、10 d;利用砧木、接穗残株进行嫁接,嫁接苗成活率、木质部输导能力、砧/穗接合力及35 d嫁接苗净生长量与初次嫁接苗无显著差异。茄子残株嫁接苗砧木与接穗培养成本明显低于初次嫁接苗,按万株嫁接苗计,可节约生产成本696.4元。综上,茄子嫁接后砧/穗残株可以嫁接再利用,并可提高经济效益。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.
