    Evaluación de cama caliente en la propagación asexual de arándanos (vaccinium myrtillus)
    (2023-12) Vaca Mayorga, Christian Ruperto; Curay Quisphe, Segundo Euclides
    The present investigation was carried out on the property of Eng. Ruperto Vaca, in the Tambo Centro hamlet of the Cevallos Canton of the province of Tungurahua, the origin of the cuttings is from 3-year-old plants from the Corp Harvest company located in the Huachi Grande parish from the Ambato canton. An experimental investigation was carried out with a completely randomized design with the following specifications: 3 types of substrates, 2 classes of hormones, 2 temperatures and their respective control, Tukey significance tests were applied at 5% to differentiate between treatments. The analysis of variance was carried out and the Tukey test at 5 was performed on the source of variation corresponding to treatments. The data that was analyzed were: Growth of the cutting, length of the root, days to rooting, percentage of rooting, number of roots. The economic analysis was carried out using the benefit-cost relationship. It is concluded that the temperature applied to the blueberry cuttings with the implementation of hot beds directly affects the rooting of the cuttings since in all the variables studied in this experiment the best results were achieved. By studying the effect of rooting hormones, it was determined that the application of ANA influences the variables of cutting growth and root length, while the days to rooting, the percentage of rooting and the number of roots had better results with the IBA application. The substrate that provided the most suitable conditions for the rooting of blueberry cuttings in the experiment was coconut fiber, which had the best results in the variables studied, which is why it was established as the best to be used for blueberry rooting. in warm beds.
