Propagación vegetativa del aguacate (Persea americana miller) variedad hass, mediante el uso de hormonas enraizantes en la zona de Quevedo

The cultivation of avocado (Persea americana Miller) var. Hass is one of the alternatives that makes its way in the Ecuadorian economy, due to the excellent climatic conditions of the inter-Andean alley that makes it an opportunity that should be exploited to the fullest. The majority of existing plantations in the country come from grafted plants, however, many times seed plants with productivity levels qualified as sub-optimal are still used due to the productive heterogeneity that is generated between individuals. The present investigation was carried out in the Quinsaloma area and seeks new technologies in vegetative propagation that allow for more homogeneous plantations and reaching higher production levels, for which a trial was available under a randomized complete design, evaluating the four doses of auxins naphthaleacetic acid (ANA) and indolbutyric acid (AIB) in the rooting of stakes: 2500, 3000, 3500 and 4000 mg / Kg, plus a control treatment without hormones. The variables evaluated consisted of the rooting percentage (PE), root length (LR), number of roots (NR) and number of shoots (NB). The results showed that the dose of 3500 mg / kg reached 23.34% of PE, in the same way, it reached a higher NR with 2.75 and 1.58 cm on average of LR, while for NB it reached on average 2.75. Economically, the project showed profitability by applying the dose of 3500 mg / kg, where a B / C ratio of 1.09 was achieved, compared to the other treatments that reached 0.04 and even negative values. Keywords: Auxins, Hass, induction, rhizogenesis.
