The objective of this work was to evaluate the rooting and sprouting of pitaya (Hylocereus undatus) cuttings under different shading levels. Shades obtained by screen were: 37.8%, 49.6%, 86.3%, and under the sun. The following characteristics were analyzed: cuttings survival (%), shooting (%), number of shoots, shoots average length (cm), shoots dry matter (g), rooted cuttings (%), root average length (cm), root volume (mL), root dry matter (g), and chlorophyll concentration a and b (mg g-1). Survival percentage means were between 90 and 100%. Responses for shooting and shoots dry matter were quadratic, with maximum point at 23.48% and 42.7 % of shading, respectively. In regards to cuttings rooting, means were between 80 and 95%. Root volume and root dry matter showed linear reduction according to shading level. Chlorophyll contents a and b showed linear increase in function o shading level. Partial shading ( between 23 and 42%) increased the percentage of cuttings with shoots, the accumulation of dry matter on them, and affected volume and dry matter accumulation on roots in pitaya nurseries propagated by cuttings. |
