Evaluación de tres tipos de injertos en cuatro variedades de aguacate (Persea americana) para la producción de plantas en vivero, cantón Guano, provincia de Chimborazo.

Abstract

The following investigation's objective was to carry the present investigation proposes: to evaluate three types of grafts in four varieties of avocado (Persea americana) for the production of plants in a nursery; carried out in the El Rosario parish, of the Guano canton. A randomized complete block design (DBCA) with a tri-factorial arrangement in subdivided plots was used, with forty-eight treatments and three repetitions. The treatments correspond to three types of graft: Pua terminal pest (M1), Yolk (M2) and lateral Pua (M3), in four avocado varieties: Fuente (V1), Hass (V2), Guatemalan (V3) and Antillean (V4)) in the different phases of the moon: New Moon (F1), Fourth Crescent (F2), Full Moon (F3) and Fourth Waning (F4)). For the development of the work, the percentage of seizure was evaluated, days from the graft until the appearance of the first leaves, height and diameter of the graft. According to the obtained results, a greater percentage of the waning quarter in the Antillean variety was observed, in terms of days from the graft to the appearance of the first leaves, it is achieved in the fourth quarter with the type of terminal barb graft, a greater development is achieved in full moon, with the type of terminal barb graft in the hass and strong variety. The treatments with the greatest cost benefit are those carried out in the fourth quarter with the type of terminal barb graft, in the Antillean variety. The conclusion is that in the phase of full moon and quarter waning with the type of terminal barb graft in the Antillean, hass and strong varieties a greater effect is observed on the agronomic behavior of the grafts.
