Morfometria de Plantios de Dipteryx odorata Aubl Willd (Cumaru) no Oeste do Pará

Abstract

A espécie Dipteryx odorata Aubl Willd (Cumaru) pertencente à família das leguminosas, tem se destacado entre as espécies florestais utilizadas em plantios silviculturais, fato justificado pelo seu potencial de produtos madeireiros e não madeireiros. Por essa razão o objetivo deste trabalho foi analisar as características morfométricas da espécie em diferentes arranjos florestais no oeste do Pará. Foram amostrados 5 sistemas localizados nos municípios de Alenquer, Belterra e Mojuí dos Campos, onde foram coletadas variáveis de 25 indivíduos, obtendo-se altura total, altura comercial, inserção de copa, diâmetro à altura do peito e diâmetro de copa. O sistema 3 (Cumaru e laranja) apresentou as maiores médias de Diâmetro a altura do Peito (14,1 cm ± 2,60 cm), Altura Total (9,88 m ± 1,69 m), Diâmetro de Copa (7,25 m ± 0,76 m), Comprimento de Copa (7,83 m ± 1,20), Área de copa (41,72 m2 ± 8,69) e Proporção de Copa de 75%. O Índice de Saliência mostrou que a espécie apresenta baixa taxa de crescimento, o Grau de Esbeltez indicou plantios instáveis, necessitando da adoção de desbastes. O sistema 2 (Cumaru, graviola, pimenta-do-reino, açaí e cupuaçu) apresentou os melhores valores de IMAh (1,94 m3), IMAd (1,64 cm), Inserção de copa (3,46 m ± 0,74 m), altura comercial (9,88 m ± 1,11 m), Formal de Copa (0,78) e Índice de Saliência (39,4). Os sistemas 2 e 3, foram considerados os mais produtivos pelas variáveis morfométricas, indicando que podem servir de modelos de arranjo para o plantio dessa espécie na região.

Dendrometric Relationships and Biomass in Commercial Plantations of Dipteryx spp. in the Eastern Amazon

“…Sampling of tonka bean trees was carried out in six stands of different ages and spatial arrangements, four of these being agrisilvicultural systems, one silvopastoral system, and one monoculture area (Table 1). More detailed descriptions of the sampled systems can be found in [16,17,42]. The predominant climate in the region is hot and humid, with rainfall concentrated in the first half of the year, an average annual temperature between 25 • C and 27 • C, an average air humidity of 86%, and an average annual rainfall of 1920 mm, varying in terms of monthly rainfall between 170 mm and 60 mm [38], being part of the Am3 climate subtype, except for the northern portion of Belterra, with an Am4 subtype [39].…”

More detailed descriptions of the sampled systems can be found in [16,17,42]. The sampling of the measured trees was carried out systematically, excluding individuals located at the edges of plantations and the subsequent trees, as shown in Figure 2.…”

“…Among the various species used in reforestation in the Amazon, those of the genus Dipteryx, popularly known as tonka beans, stand out. The adoption of tonka beans as a tree component in agroforestry systems is a widespread silvicultural practice by small and medium-sized producers in the Eastern Amazon [16,17]. Part of the interest of producers is related to the possibility of multiple uses of the species and its growth potential in degraded areas [18,19].…”

“…In the context of the Amazon region, the cultivation of native species for timber purposes is still at an early stage, and it is mainly aimed at small producers, as evidenced by mapping works carried out in western Pará [16,37]. In this sense, the objective of this work is to characterize and compare the relationships between dendrometric variables in populations of Dipteryx spp.…”

“…The species Dipteryx odorata Aubl Willd known as cumaru, is widely used in folk medicine. Belonging to the Fabaceae family, the plant is called by different names, depending on the region, such as cumaru do Amazonas, cumbari sarrapia, cumaru purple, cumaru-ferro, cumaru da Folha Grande, cumaru true, cumari and internationally it is known as Tonka [5,6,7]. The species attracts great interest due to the uses attributed to it in popular medicine.…”
