Propagação vegetativa de serigueleira com uso de enraizadores sintéticos.

Abstract

Spondias purpurea L. is a deciduous fruit tree native to Mesoamerica that spread throughout South America and has adapted well to tropical and subtropical climates. In Brazil, it is common to find the seriguel tree in the North, Northeast and Southeast regions. It has fruits with excellent flavor and rich in nutrients, much appreciated in the Brazilian Northeast. The seriguela tree has economic, social and environmental importance, and during the seriguela harvest several informal jobs are generated, in addition to its fruits being processed and sold in supply centers, cooperatives, markets, open-air markets and on the sides of highways, generating income for the local population. It is found mainly in home and small orchards and in domestic backyards. S. purpura reproduces almost exclusively asexually. Asexual propagation through cuttings is one of the viable options, but it presents some difficulties such as the delay in rooting and forming the crown of the new tree, in addition to the fact that, in most cases, the cuttings produce shoots, but do not root. The present work aims to analyze the performance of synthetic rooters such as naphthalene acetic acid and indolebutyric acid in the propagation by cuttings of Spondias purpurea L. The experiment was carried out in the municipality of Picuí in Paraíba, between the months of June and August 2023. 20 cm cuttings were used in this experiment, the base of which was immersed in a hydroalcoholic solution of different concentrations of the aforementioned acids for 10 seconds. The variables investigated were root emission, green and dry phytomass. It can be concluded that the synthetic rooters used did not influence root formation Spondias purpurea, and only presented satisfactory results for survival and callogenesis of the cuttings.
