This research evaluated the different products as growth media influence on some Mammillaria species propagation, in order to ornamental plants obtained. Some Mammillaria species were tested: Mammillaria elongata - M.el; Mammillaria mazatlanensis -; Mammillaria neomystax -; Mammillaria obconella - M.ob; Mammillaria prolifera -; Mammillaria spinigemmatus - M.sp; Mammillaria blanckii - Different substances, as growth media,were used: sand - San; garden soil - GS; perlite - Per; peat - Pea; hydroculture - HydC; agar-based medium - InVitro. Based on these, resulted the experimental variants: San+GS - V1; Per+GS - V2; Pea - V3; San+Pea - V4; HydC - V5; InVitro - V6. In Vitro method (V6) provided the best spread rate for most Mammillaria species tested, but Mammillaria neomystax recorded the best result in the V5 variant. Some Mammillaria species had good propagation rate in more growth media (eg. Mammillaria neomystax in V1 - San+GS; V4 – San+Pea; V5 - HydC), and others only in a growth media (eg. Mammillaria spinigemmatus in V6 - In Vitro). Based on Principal Component Analysis, 56.171% of variance was explained by PC1, and 25.00% of variance was explained by PC2. Cluster analysis, based on Euclidean distances, facilitated the grouping of the studied Mammillaria species, in conditions of statistical safety (Coph.corr. = 0.857). Mammillaria mazatlanensis ( and Mammillaria prolifera ( species, showed the highest degree of similarity, SDI = 2.027.
