Abstract:
The seriguela (Spondias purpurea L.) is a deciduous and fruitful tree native to Central
America and easily adapted to tropical, arid and semi-arid climates, and with that, it has
spread to several countries in South America. In Brazil, it is usually found in regions such as
the North, Northeast and Southeast. Its reproduction occurs sexually in wild populations, and
asexually in cultivated populations. In asexual reproduction, large cuttings are commonly
used, planted directly in the field. However, this practice presents some difficulties, such as
the delay in rooting and crown formation in the new plant. It is necessary that these problems
are overcome in order to obtain reproductive success. Because of this, the present work aimed
to analyze the performance of rubber plants implanted through the cutting method. The field
research was conducted in the municipality of Jaçanã, RN, at the Chã da Bolandeira site, from
July 2021 to June 2022, continuing the analysis of variance of the experiment, implemented a
year ago. An experimental design was adopted in randomized blocks, distributed in four
blocks, each one with 20 different cuttings, thus reaching a total of 80 plants. The treatments
tested were distributed throughout the experiment, where each treatment had stakes of
different heights, as follows: T1-0.4m; T2-0.6m; T3-0.8m; T4-1.0m; T5-1.2m. Regarding the
characteristics of the plant, the following were analyzed: branch length, stem diameter and the
occurrence of damage caused by pests in the plantation. The results showed that the largest
cuttings from treatments T4 and T5 had the best numerical values in all variables studied. The
research showed that the insects that most devastated the experiment were termites, where
they reached 30% of the plants in the experiment.
