Dragon fruit (Hylocereus undatus) belongs to the Cactaceae family and is a species cultivated for fruit consumption due to its rich content of vitamins, minerals and an excellent source of antioxidants (betacyanin), but also vegetable albumin, vitamins and water-soluble fibres. The best method for rapid plant multiplication is cell and tissue culture, so in this study we followed the influence of different growth hormones on micropropagation and rooting, in two varieties of pitaya (Vietnamese White dragon fruit and Red Jiana Dragon Fruit). Thus, the shoots obtained from the seeds were grown on Murashige and Skoog (MS) culture medium supplemented with two types of cytokinins: 6-benzyl amino purine (BAP) – 2.5 mg/l and kinetin (KIN) – 2 mg/ l, respectively naphthaleneacetic acid (NAA) – 1 mg/l, for multiplication, and for the rooting of the shoots, Murashige and Skoog (MS) medium supplemented with 1 mg/l IBA, respectively the medium without growth regulators, was used. The results obtained were different depending on the variety, but also on the type of growth regulators used.
