“…For pseudostem diameter, this study revealed that both paclobutrazol and mepiquat chloride generated a reduction in the thickness of the pseudostem when compared to the control (Tab 1). This result is similar to that obtained by Maia et al (2008), who submitted two banana cultivars to treatments with paclobutrazol via foliar spraying and obtained a reduction in the diameter of the pseudostem.…”

Colombia is the fourth largest producer of plantain in the world, with a harvest of 3,539,252 t. Various biotic and abiotic factors affect yields, including phytoparasitic nematodes that are a major constraint in this crop. For this reason, strategies are being sought to improve the performance of this plant with this cosmopolitan pest. This research evaluated the effect of two hormonal regulators on the growth and development of the Dominico plantain. The experiment design had treatments that were divided plots, where the main plot corresponded to the type of product, and the sub-plot corresponded to the concentrations of paclobutrazol and mepiquat chloride in the different doses: 0, 250 and 500 mg L-1. The experiment unit consisted of ten plants with four replicates. The evaluated variables were plant height, diameter of the pseudostem, number of functional leaves, length and diameter of the roots, number of nematodes and variables for production quality. The two growth regulators reduced the plant height before emergence of the flower; paclobutrazol reduced the height by up to 40%, while mepiquat chloride reduced the height by up to 6.7%. There were no statistical differences in the production per plant, where the production with paclobutrazol was 14 kg/plant and, with mepiquat chloride, was 15 kg/plant. The control was 14.5 kg/plant. The use of growth regulators did not significantly restrict the damage caused by nematodes; however, paclobutrazol performed better as a growth regulator in the Dominico Hartón plants.

“…This indicates that, when the mother plant is felled at harvest time, the plant will regrow, guaranteeing the longevity of the crop in the area (Bolfanaria et al, 2014). In addition to its importance for the longevity of the plantation, surplus shoots can also be transferred to new areas by the farmer (Maia et al, 2008).…”

As the arrangement of the species is fundamentally important to guarantee the effectiveness of agroforestry systems, it is important to test different combinations of species with varying levels of economic potential. The study was based on the analysis of the initial development of an agroforestry system formed by native tree species and other plants of economic interest, intercropped with green manure species under the edaphoclimatic conditions of Nova Xavantina in Mato Grosso, central Brazil. The study was conducted in an experimental plot on the Nova Xavantina campus of Mato Grosso State University. The plot was arranged in randomized blocks, in a simple agroforestry system of the alley type, with the plants arranged in rows, in a 4x2 factorial design (four fruit species x two legumes). The fruiting species included five trees – Bixa orellana, Spondias lutea, Byrsonima crassifolia (L.) Rich, Pouteria ramiflora, and Theobroma grandiflorum, and the banana, Musa sp. (the “BRS Princesa” cultivar). Two combinations of legume species were tested – (i) Cajanus cajan and Vigna unguiculata,and (ii) Mucuna aterrima and Canavalia ensiformis. Tree growth was assessed based on four phytometric parameters – plant height, stem diameter, the number of leaves, and percentage survival, while for Musa, the parameters were height and pseudostem circumference, and the number of active leaves and shoots. Bixa orellana and S. lutea were the species best adapted to the edaphoclimatic conditions found in the experimental plot, with all (100%) of the Bixa plants surviving throughout the study, and a survival rate of over 70% in S. lutea.
