“…Although we have no current data at this time, this value is similar to that reported for J. curcas, which can produce 2000 liter/ha oil per year (Azam et al 2005). In addition, the oil production of A. aculeata, another similar species, may reach 16000 -25000 kg of fruit per hectare and may produce up to 6200 kg/ ha of oil (Pires et al 2013). In addition to the high oleic acid content, A. intumescens grows well in areas with low soil fertility, has tolerance to fire and can be cultivated in areas that undergo prolonged drought.…”

In this study, pulp and kernel of fruits from six Arecaceae species were subjected to proximate analysis, fatty acid composition and total carotenoid content analysis. The species with the highest carbohydrate, lipid and protein values were Ptychosperma macarthurii (70.1 g/100 g in the kernel), Syagrus cearensis (40.6 g/100 g in the kernel), and S. coronata (20.6 g/100 g in the pulp). The ash content ranged from 0.61 to 7.51 g/100 g. Lauric, palmitic, and oleic acids were the major fatty acids identified. The total carotenoid contents and retinol activity equivalents were highest in the Pinanga kuhlii (180.3 µg/g) and Acrocomia intumescens (138.0 µg/g) pulp oils. Retinol activity equivalents varied between the investigated species (456 to 1515 μg RAE/100 g). Native species such as A. intumescens, S. coronata, and S. cearensis are good sources of fresh food for the underserved populations that inhabit poorly developed areas such as the semi-arid region of Brazil. P. macarthurii, an exotic species, is an excellent source of ash and carotenoids, demonstrating its potential both as a food source and as bioactive compounds. Pulp and kernel of A. intumescens, could be a good alternative feedstock for soap and biodiesel production, respectively.

“…Lodd). This species provides a high pulp oil yield, close and even higher than oil palm 4,5 , with suitable features for oil-based products besides a large amount of useful coproducts 6,7 . However, the development to obtain high quality macauba pulp oil is still in the beginning.…”

“…This species also has a low germination rate that is due to physiological traits, rather than physical dormancy (Ribeiro et al 2011;Bicalho et al 2015). A. aculeata is widely distributed throughout tropical America (Motta et al 2002;Pires et al 2013). It is a pioneer species that colonizes pastures and open areas in the Cerrado domain, which is prone to frequent fire events.…”

Do the structures of macaw palm fruit protect seeds in a fire-prone environment?

Fire is an abiotic disturbance that regulates vegetation structure and biodiversity. Some plant species have adapted to fi re prone environments by evolving protective structures. Acrocomia aculeata (macaw palm) is widely distributed throughout tropical America, and is found in environments continuously infl uenced by anthropogenic fi re. We aimed to determine whether the fruit characteristics of A. aculeata enable seeds to resist the eff ects of fi re and also the consequent eff ects of fi re on fruit biometric traits and embryo viability. After a fi re event in a region of pastureforest transition, we marked 30 individuals of A. aculeata. Th e trees were separated by UPGMA analysis into 5 groups according to fi re exposure, ranging from trees with no exposure to trees with fruit completely exposed to fi re. Fruit exposure to high temperatures led to lower values in fruit fresh weight, length, density, and processable mass.Fire had no signifi cant eff ect on seed biometric variables, because of the structures of the fruit, including its lignifi ed endocarp and its insulating and mucilaginous mesocarp. Th ese structures helped to maintain the embryos viability by preventing oxidative damage. In conclusion, the fruit structure of the macaw palm may facilitate seed persistence, even when subject to increasingly frequent fi re events.
