The red pitaya is a cactacea that has been more and more demanded both for theproducers and for the consumers. Nevertheless, there are still several aspects about its cultivation that need to be elucidated, in order to provide a good culture development and profitability to the producer. This work was done aiming to study the effect of substrate in the vegetative propagation of this fruit, commonly done through cutting. The experiment was carried out in a lath house from the Departamento de Produção Vegetal of FCAV - UNESP. Cuttings of adult plant were used and placed in different substrates for rooting, composing the following treatments: (1) soil, sand and manure of tanned corral mixture, in the proportion of 3:1:1; (2) coconut fiber (Amafibra); (3) sand and (4) commercial substrate (Plantmax). For each treatment, 4 replications with 10 cuttings were done. Fresh and dry mass of roots (grams) and volume (mL) were evaluated. A completely randomized design was used, and data evaluated by Tukey test at 5% probability. In the conditions in which the experiment was accomplished, one can conclude that there was influence of the substrate in the fresh mass and volume of the roots, being the substrate (1) the most appropriate for seedlings formation of this species.
