“…This study revealed large variations in biometric parameters and composition between A. aculeata fruits from different accessions in Costa Rica, as has been observed in previous studies performed both in Costa Rica (Schex et al 2018) and other Latin American regions (Ciconini et al 2013;Lescano et al 2015;Castro et al 2017;Coelho et al 2019). The fruits collected in Costa Rica were smaller than to those of Brazilian palms documented in several previous reports (Ciconini et al 2013;Castro et al 2017;Vianna et al 2017).…”

“…However, even smaller sizes have been reported for A. aculeata fruits at a similar maturity stage collected in Costa Rica (Schex et al 2018) and for some Brazilian accessions (Manfio et al 2011;Ciconini et al 2013), indicating strong variability among populations. Large biometric variability is therefore characteristic of wild Acrocomia populations and has been associated with genetic variability and environmental influences -in particular soil chemical properties and soil water availability-on plant functioning (Manfio et al 2011;Coelho et al 2019).…”

“…However, it is to be expected that Acrocomia will be produced in systems different from the plantation management practiced for E. guineensis. Acrocomia adapts more easily to environments with lower competition for light and nutrients than to dense forests (Coelho et al 2019). Therefore, it is probably more suitable for agroforestry systems than for plantation management.…”

“…Acrocomia has not yet been domesticated and biometry, oil yield, and composition have only been studied in wild genotypes in Brazil (Cardoso et al 2017;Coelho et al 2019), where large phenotypic variability has been associated with environmental conditions and genetic diversity (Abreu et al 2012). The breeding of genetically improved plants with optimized height, increased productivity and drought tolerance is one of the major directions in present Acrocomia research (Cardoso et al 2017;Colombo et al 2018).…”

“…In studies from Brazil, it was found that productivity-in terms of oil yield-is determined by fruit size and oil content, which are in turn related to environmental parameters (e.g. soil conditions, water availability), as well as genetic variability (Ciconini et al 2013;Castro et al 2017;Coelho et al 2019). In these studies, the best performance-in terms of productivity, fruit characteristics and oil contentwere found in regions with higher precipitation and mild temperatures, both typical features of the Atlantic Rainforest (Castro et al 2017).…”

Acrocomia aculeata fruits from three regions in Costa Rica: an assessment of biometric parameters, oil content and oil fatty acid composition to evaluate industrial potential

Due to increased global demand for vegetable oils, diversification of the supply chain with sustainable sources is necessary. Acrocomia aculeata has recently gained attention as a multi-purpose, sustainable crop for oil production. However, the information necessary for effective selection of promising varieties for agricultural production is lacking. The aim of this study was to assess variability in fruit morphology and oil composition of individual Acrocomia aculeata plants growing wild in different climatic regions of Costa Rica. Fruits at the same ripening stage were collected at three locations, and biometric features, oil content, fatty acid composition of oils from kernels and pulp, as well as fiber composition of husks were determined. Biometric parameters showed high variability among the regions assessed. Moreover, oil content and relative proportions of unsaturated fatty acids were higher at the most tropical location, whereas lauric acid content was lowest under these conditions, indicating a potential environmental effect on oil composition. Pulp oil content correlated positively with annual precipitation and relative humidity, but no clear relation to temperature was observed. The oil chemical composition was similar to that reported for Elaeis guineensis, suggesting that Acrocomia aculeata from Costa Rica may be a suitable alternative for industrial applications currently based on African palm oil. Analysis of husks as a coproduct revealed the possibility of obtaining materials with high lignin and low water and ash contents that could be used as a solid bioenergy source. In conclusion, Acrocomia aculeata oil is a promising alternative for industrial applications currently based on African palm oil and byproducts of its oil production could find additional use as a renewable energy source.

The oilseed palm genus Acrocomia is suitable for sustainable oil production in South America. The high phenotypic diversity of wild populations poses a challenge for the delimitation of the genus. Comparing the inflorescence architecture, a first‐order panicle, and staminate and pistillate flower traits could be a valuable tool in resolving the taxonomic disarray. Thus, this study aims to characterize the differences in the inflorescence architecture and floral structures of three common and economically significant Acrocomia species: A. aculeata, A. totai, and A. intumescens. Biometric traits of the inflorescence architecture and floral structures of various Acrocomia accessions in an ex situ germplasm collection in Brazil were assessed. The unweighted pair group method with arithmetic mean (UPGMA) cluster analysis based on the Gower distance was used to measure dissimilarities between the individual plants of the accessions. To our best knowledge, this study provides the first evidence of the presence of second‐order rachillae in the genus Acrocomia. Evaluated traits showed a high level of variation within and between accessions, emphasizing the phenotypic diversity of the genus. The accessions of A. totai were distinguishable from those of the other two species by their inflorescence architecture and flower traits. The dissimilarities between A. aculeata and A. intumescens were not sufficient to differentiate both. In conclusion, the quantitative assessment of inflorescence and floral traits is a valuable tool for taxonomic resolution of the genus.

Macaúba is a tropical palm native in South and Central America, and its fruits present a high-quality oil for biodiesel production. Notwithstanding, macaúba's wastes and by-products are not usually repurposed as energy sources. This study shows a bibliometric analysis to assess macaúba's current applications and to investigate other energy recovery routes for its by-products. All the investigations focused on information about the main research fields related to macaúba. The study showed that only 397 articles and reviews were published from 1900 until 2021, and Brazil is the leading publisher. Although oleic and protein macaúba's by-products are applied as animal feed, some conversion routes related to the lignocellulosic contents, present in non-edible parts, were identified thermal conversion, combustion, gasification, pyrolysis, biochemical conversion, fermentation, esterification, and anaerobic digestion.From the agricultural perspective, plant characterization, germination, embryogenesis, and seed development were also found. From the bibliometric study, the different potential applications of macaúba for energy, pharmaceutical, and food purposes were listed to support the identification of a knowledge gap on its by-products revaluation.
