Estaquia da cajazeira com uso de enraizadores comerciais sob estufim

Abstract

The yellow mombin (Spondias mombin L.) is a plant that produces fruit of bittersweet taste, with great demand on markets and agribusiness, being consumed in natura or in the form of pulp, juices and ice creams. The greater part of production is derived from existing trees in backyards and in the forests, which are heterogeneous and have great genetic variability. The solution is to cultivate cloned plants with desirable characteristics; and cloning for stem cuttings can be a viable method. This study aimed to evaluate the rooting of cuttings of yellow mombin tree submitted to different commercial rooters (Rhizopon®, Sela Gel® and Sela Gelr/Rhizopon®) in the presence and in the absence of estufim. We used 7 treatments: Rhizopon® without estufim; Rhizopon® with estufim; Saddle gelr without estufim; Selae gelr with estufim; Sela Gelr/Rhizopon® without estufim; Sela Gelr+Rhizopon® with estufim; plus an additional treatment, Without cruise and without estufim, repeated in 4 randomized, with ten cuttings per plot, with the final evaluation at 86 days after planting. The use of rooters did not significantly influence the percentage of rooting, despite the increase in the rooting when compared with the witness, 10% of rooting. With the Rizhopon rooting was 33.75%, followed by the mixture of Rizhopon+Saddle Gel which was 28.75%. The use of estufim has resulted in a greater number of seedlings ready for planting, 23.33% and 14.17% without estufim. The rooters provided a greater rooting of cuttings, and estufim a greater number of seedlings ready for planting.
