The experiment aimed to evaluate the behavior of the grapevine rootstocks IAC 313 "Tropical" and IAC 572 "Jales" in nutrient solution with different aluminium concentrations. The experiment was conducted in green house conditions of the Vegetal Production Department/Horticulture Sector, of the Faculty of Agricultural Sciences - UNESP/Botucatu. Five aluminium levels were used, as known: 0, 10, 20, 30 and 40mg L-1in the form of AlCl3.6H2O. The samples were colleted every 15 days to obtain the physiologic variables. The experimental design adopted was the subdivided split-plots, fully randomized and with 3 replications. The variables evaluated were: absolute and relative growth rates, leaf weight and aerial parts/root ratio. The IAC 572 "Jales" rootstock, when grown in 10mg Al L-1 in the solution, presented higher absolute and relative growth rates and higher dry matter redistribution from leaves to other plant parts. The IAC 313 "Tropical" rootstock, in the same condition, presented a sharp decrease of these variables.
