Propagación vegetativa de arándano (Vaccinium corymbosum L.) con diferente material vegetal, enraizantes y sustratos bajo invernadero

Abstract

In the Pichincha province, Cayambe canton, at an altitude of 2800 masl, the present investigation was carried out, with the purpose of verifying the effect of the position of cuttings, rooting sources and substrates on the vegetative propagation of blueberries (Vaccinium corymbosum L.). For this, horizontal and vertical cuttings of 2-year-old blueberry of the Biloxi variety, 3 sources of rooting agents based on aloe vera (Aloe vera), willow (Salix erythroflexuosa) and hormone (ANA) and 2 substrates (blonde peat and humus). The length of the vertical cuttings was 25 cm and 6 cm for the horizontal ones with a minimum of 3-4 buds. Regarding the preparation of the rooting agents, in the case of the aloe vera, the gel was separated and placed in water in a 1:1 ratio, for the willow, 1L of water was boiled for 20min and 200 grams of young branches were added. , covered and left to rest for 2 days. Next, the cuttings were placed in these rooting agents for 24 hours, while the ANA hormone was placed on the day of the trial installation. For this research, a completely randomized design (DCA) was improved with a 2x3x2 factorial arrangement with three repetitions, where three variables were measured (shoot length, rooting percentage and root length). Statistical analysis showed that t7 (vertical cutting, aloe vera, peat) was the best treatment in all variables, although in general the vertical position of the cuttings with all the rooting agents and peat as a substrate gave the best result. It is worth mentioning that the 60 days in which it was planned to evaluate the variables was not enough time, since the emission of roots had just begun
