Starting from the micropropagation and selection of sweet potato varieties that responded best to in vitro water stress conditions, this study aims to identify the most effective methods of plantlets acclimatization in protected space. The three-factor experiment was carried out by combining the following factors, analyzed in several gradations, as follows: experimental factor A-variety, experimental factor B-substrate, experimental factor C-irrigation. Regarding the influence of the culture substrate and the irrigation variant on the tuberization of the three varieties of sweet potato (CD/1, CD/3, CD/4), the CD/1 genotype is noted on the normal irrigation variant and the use of the culture substrate containing: red peat, black and perlite (2: 1: 1), with a very significant positive difference (5.00) at the average number of tubers/pot. On the same culture substrate, but in a deficient level of irrigation, the CD/3 variety recorded at the average mass and the number of tubers a distinctly negative difference (-131.63 g) and a negative significant difference (-3.25), compared to the control variety (CD/4).
