Cultivo de estacas e miniestacas de jaqueira com uso de enraizadores sintéticos.

Abstract

The jackfruit tree (Artocarpus heterophillus Lam.) is a fruitful plant from the Moraceae family, native to India. Brought and disseminated in Brazil in the colonial period. Today it is present throughout the country, mainly on the coast. The objective of this work was to investigate the vegetative propagation of Artocarpus heterophillus, using synthetic rooters in different proportions, for the cultivation of cuttings and minicuttings. The experiment took place in the municipality of Baraúna - PB, from August 7, 2023 to November 10, 2023. The design was completely randomized with the treatments designated as T1 = Distilled water only; T2 = IBA 2%; T3 = ANA 0.4% and T4 = IBA + ANA 1%. Two experiments were set up, one with 8 cm minipiles and the other with 20 cm piles, which were submerged for 10 seconds each in different concentrations of indolebutyric acid and naphthalene acetic acid. Minicuttings and jackfruit cuttings were not responsive to the rooters used. It was concluded that there was no effectiveness of these rooters on jackfruit cuttings and minicuttings. It was also found that there are few published works on cultivation techniques for Artocarpus heterophillus Lam. There is a need to study methods that facilitate cultivation efficiently so that excellence in the genotypic and phenotypic characteristics of this species is maintained.
