Porcentaje de luminosidad y grano de lijas en el prendimiento del injerto del cacao en Puerto Bermúdez

Abstract

The influence of the percentages of luminosity and number of sandpaper grains in the grasping of the central spike type graft of Theobroma cacao L., which was carried out in the San Pedro Native Community, of the District of Puerto Bermúdez, Province of Oxapampa, was studied. Pasco Department. Three nurseries were built with a Raschel mesh roof, with shade percentages of 40%, 60% and 80%. The seeds for the patterns came from the CCN-51 clone, which were sown in 6 x 8-inch bags containing substrate and placed in a nursery. The rods for grafting corresponded to clone CCN 51, which were extracted the same day as grafting. Three grafting blades were sharpened using three sizes of water sandpaper grains (400-A, 600-A and 1000-A) respectively, executing the central spike grafting procedure, to later condition the grafted seedlings in the three built nurseries. , evaluating at 30 and 60 days after grafting. The Completely Random Design (DCA) was used with a 3 x 3 factorial arrangement, concluding that the percentage of luminosity has no influence on the percentage of seizure, being the number of sandpaper grit 1000-A which achieved 100% of seizure. Likewise, the interaction 60% of luminosity plus the number of sandpaper grain 1000-A showed greater averages of shoot length and number of leaves, however, the interaction 80% of luminosity plus the number of sandpaper 1000-A achieved greater averages of number of shoots, and the interaction 60% of luminosity plus the number of sandpaper grit 400-A achieved higher averages of bud diameter, finally, 60% and 40% of luminosity achieved the best averages of pattern diameter.
