Abstract

THE CULTIVATION OF PITAHAYA (H. MEGALANTHUS, H. UNDATUS AND H. PURPUSII) IN RECENT YEARS HAS HAD A REMARKABLE PROJECTION AT INTERNATIONAL AND NATIONAL LEVEL, WHICH HAS LED RESEARCHERS TO OBTAIN PROMISING MATERIALS, WITH GENETIC AND BIOTECHNOLOGICAL BASES, THE LATTER BEING THE ONE THAT HAS BEEN EFFICIENT FOR ITS ACCELERATED PROPAGATION. THE AIM OF THE PRESENT WORK WAS TO EVALUATE THE RESPONSE OF THE COMBINATION OF AUXINS AND CYTOKININS IN THREE SPECIES OF PITAHAYAS FROM CLADODE SEGMENTS. A NON-PARAMETRIC DESCRIPTIVE STATISTIC WAS USED FOR THE QUALITATIVE VARIABLES OF ESTABLISHMENT AND ACCLIMATION AND A COMPLETELY RANDOMISED DESIGN (CRD) WITH 27 TREATMENTS, 10 REPLICATIONS AND 5 EXPERIMENTAL UNITS WAS USED FOR THE EVALUATIONS OF THE QUANTITATIVE VARIABLES, IN A TRIFACTORIAL ARRANGEMENT: THREE SPECIES (H. MEGALANTHUS, H. UNDATUS AND H. PURPUSII); THREE TYPES OF CLADODE SEGMENTS (APICAL, CENTRAL AND BASAL) AND THREE CULTURE MEDIA
