The use of water of inadequate quality is pointed out as one of the causes of failure inseedling production. Absence of indication of salinity tolerance for West Indian Cherry (Malpighia emaginata D.C), an experiment was carried out in randomized block design, with the objective of studying the effects of 6 level of eletrical conductivity of irrigation water (ECw) varying from 0.5 to 5.5 dS m-1 on the formation of seedlings of West Indian Cherry utilizing clone BV1 as rootstock and clone BV7 as graft. The irrigation water of desired ECw was prepared maintaning equivalente proportion of 7:2:1, among Na:Ca:Mg, respectively. The water growth of rootstock was evaluated at 50 days after application of treatments and of grafted seedlings at 15 and 50 days after grafting. The water with ECw of 5.5 dS m-1 does not affect the adequability of rootstock for grafting neither the sprouting of graft at the time of transplanting.
