Evaluación de tres dosis de ácido naftalenacético (ANA) en la formación de racimos del cultivo de palma de aceite, híbrido interespecífico OxG, en la zona de Santo Domingo de los Tsáchilas, cantón La Concordia.

Abstract

Oil palm in Ecuador has faced phytosanitary challenges that have been solved with the use of new tolerant genetic materials such as interspecific hybrids OxG (Olifera x Guineensis). These new crops require manual pollination, and their implementation must be carried out with the use of growth regulators such as naphthaleneacetic acid (ANA). With the objective of determining its effect on the production of fresh fruit bunches, three doses were evaluated, 240 mg, 480 mg and 720 mg of ANA applied during the receptive phase of the female inflorescence in 5-year-old plants, plus a reference control that is used at commercial scale in this crop. The results obtained showed that the treatment with the highest dose achieved the best bunch weight and fruit yield per hectare, with statistical differences over the other doses evaluated, which were exceeded by 18% (dose of 240 mg), and by 7% (480 mg dose). It is concluded that pollination should be carried out with the use of ANA with a dose of 720 mg of ANA per inflorescence to obtain the best productive results.
