The red dragon fruit has been a great incresing commercial interest for the producers and the consumers. However, there are still several aspects on its cultivation that need to be elucidated, providing profitability to the producer. The present work was done with the objective of getting information about the vegetative propagation of this fruitful, using different sources of material in function of the cicatrize time. The research was carried out in the lath house of Unesp - São Paulo State University - Campus of Jaboticabal, Brazil, using cuttings of red dragon fruit of different origins (adult plant, cuttings of sprouting of just-rooted plants and plant in beginning of seed development originated from seeds), submitted to 3 periods of cicatrize: 0, 7 and 14 days. After 30 days were evaluated: rooting; volume of root; length of the biggest root (cm); fresh and dry masses of the roots (gram); number and size of the sprouding in the cuttings (cm). 5 replications were realized, with 10 cuttings in each one, totaling 150 cuttings for each material. The analysis of the results obtained in this research, considering the conditions that they had been carried out, leads to conclude that: the cutting must be carried out as soon as the segmentation of the stems is done and cuttings obtained of just-rooted sprouding plants presented better results.
