Propagação assexuada de Baraúna com uso de enraizadores em câmara escura.

Abstract

The baraúna (Schinopsis brasiliensis Engl.) is a plant from the Anacardiaceae family, native to Brazil. It holds great importance in the timber and medicinal sectors. Currently, it is found in much of the country, especially in the Northeast. In order to reproduce new individuals in a short period and preserve the characteristics of the mother plant without the use of seeds, vegetative propagation involves the perpetuation of species through sexual or asexual techniques. The objective of this study was to investigate the use of different natural and synthetic rooting agents in a dark chamber for the propagation of Schinopsis brasiliensis through cuttings. The cutting method promotes the rooting of plant parts, which can include branches, roots, leaves, and even fascicles. The experiment took place in the municipality of Cuité – PB, from March 18 to July 10, 2024. For this study, five treatments were used: T1 = distilled water (control), T2 = Cyperus rotundus extract, T3 = Aloe vera extract, T4 = Aptenia cordifolia extract and T5 = Indolebutyric acid. The baraúna cuttings did not respond to the rooting agents used, and consequently, it was concluded that the rooting agents were ineffective on the plant. Furthermore, the literature contains a small percentage of published studies on propagation techniques for Schinopsis brasiliensis, highlighting the need for research on effective reproduction methods that preserve the species' genetic material.
