Propagación asexual en pitahaya roja (Hylocereus Undatus) y amarilla (Selenicereus megalanthu) en el valle del rio carrizal

The origin of the pitahaya is from the America continent, belonging to the cacti family, it is generally propagated asexually by means of braces or cladodes. The purpose of the research was to determine the appropriate method of asexual propagation of red (Hylocereus undatus) and yellow (Selenicereus megalanthus) pitahaya in the Carrizal River Valley. The treatments evaluated were: stem length 0,80m + Citokyn rooting (T1), stem length 0,80m + Trichotic rooting (T2), stem length + without rooting (T3), stem length 0,50m + Citokyn rooting (T4), stem length 0,50m + Trichotic rooting (T5) and stem length 0,50m + without rooting (T6). The variables recorded were: Percentage of rooting (%), root mass weight (g), sprouting days, number and length of shoots (cm) and percentage of mortality (%). Data analysis was performed using descriptive statistics, analysis of variance (ANOVA), and separation of means with Tukey´s test at 5% error probabilities. The results of the treatments composed of 0,80m scions showed a greater number of shoots and length in both pitahaya species, the root mass weight presented the best results in 0,50m scions and in the variables of percentage of mortality, rooting and days of budding there was equality between evaluated treatments. Likewise, the scion size factor presented significant differences (p<0,05) on certain variables evaluated such as length (cm) and number of shoots, unlike the rooting factor that did not present significant differences (p>0,05) for any of them.
