Resumo:
Spondias purpurea L. is a arboreal, fruitful species, originating in Central America,
which has spread to many countries in South America. In Brazil, it is commonly found in
the North, Northeast and Southeast. It is a species of social, economic and environmental
importance. Reproduction is sexual in wild populations, and asexual in cultivated
populations. In asexual reproduction, it is common to use large cuttings, planted directly
in the field. However, this practice presents some difficulties, such as delayed rooting and
formation of the crown in the new plant. In addition, most of the time, stakes sprout, but
do not root. These problems must be overcome in order to obtain reproductive success.
Therefore, this work aims to evaluate the performance of Spondias purpurea species
propagated by cuttings using different stake lengths during dry and rainy season in a
Caatinga area. The experiment was conducted in the rural establishment called Chã da
Bolandeira, in the municipality of Jaçanã – RN. The experimental design was carried out
in randomized blocks design (RBD), with five treatments and four blocks, each block
with four repetitions and each experimental portion composed of one plant. The
treatments tested were distributed as follows: T1-0.4m; T2-0.6m; T3-0.8m; T4-1.0m; T5-
1.2m. The plant characteristics evaluated were: stem diameter, sprout emission, branch
length and occurrence of pest damage. The collected data were submitted to variance
analysis, and the mean characteristics were compared by the Tukey test, at 5%
probability, using the computer application Sisvar version 5.6. From the analysis of the
results it was found that Spondias purpurea showed satisfactory performance. The
sprouting started 30 days after planting. The red mombin from 1.0m and 1.2m cuttings
had the best results in all variables analyzed.
