Propagação vegetativa de Ora pro nóbis (Periskia aculeata Plum)

Abstract

Ora pro nóbis (Pereskia aculeata Plum., Cactaceae) is an unconventional vegetable of food and medicinal interest. However, there is little technical information on factors that influence the vegetative propagation of the species. Thus, the objective of this work was to know the effect of the length of cuttings and the use of bokashi in the propagation of the oro pro nóbis. Three lengths of cuttings (15, 20 and 25 cm), without and with bokashi, were evaluated under nursery conditions. The experimental arrangement was in a 3x2 factorial scheme, in the randomized blocks design, with four replications. The cuttings were propagated in 500 ml plastic cups with substrate composed of + Tropstrato ® (1: 1, v / v) soil. Sprouts were evaluated weekly after the first sprout, and at 60 days after cutting, whole seedlings were harvested. The highest sprouting percentage was 60% and the sprout velocity index of 0.8737 of the 20 cm cuttings, with bokashi. The highest number of shoots per cutting was of 6,12 and 24,83 leaves in the shoots was in the stakes of 25 cm, independent of bokashi. The highest root length was 16.58 cm, and the production of fresh masses of 19.23 and 11.22 g / plant of shoots shoots of 25 cm. The cuttings with more sprouting, leaf area and physiological indices were the ones of greater length.
