“…Pequi is one of the native species of the Cerrado, widely used by the population because of its high nutritional value, variety of nutrients and especially socioeconomic value (Kerr et al, 2007;Pinto et al, 2009;Baeta, 2013). The fruit is formed by almonds and hoopoes, in which the first is responsible for the extraction of proteins.…”

The Brazilian Cerrado presents a wide variety of natural products, including the Pequi (Caryocar brasiliense). The important factor that determines the dietary and nutritional ideality of protein is degestitibility. This work aims to evaluate the protein digestibility of Pequi seeds and the presence of anti-nutritional factors. The protein Pequi almonds were extracted, toasted and untoasted. Evaluation digestibility was structurally characterized by SDS-PAGE 15%, which can be used to analyze simulated gastric fluid (SFG) and digestion in intestinal fluid (SFI) in the presence of pepsin and trypsin/chymotrypsin. The extract from Pequi almonds showed inhibitory activity and was not detected hemagglutination. The intensity of the bands according to 2S albumins, after heat treatment, did not decrease in comparison to the condition native, significantly. In the crisp crude extract, which was incubated under SGF and SIF, the intensity of the corresponding bands at 8 and 3 kDa was resistant to SGF and indigestible after 4 hours under SIF. The characterization of Pequi almonds demonstrated that the product of the crude extract has anti-nutritional factors, which were confirmed by evaluating digestibility.Keywords: Caryocar brasiliense; almonds; in vitro digestibility; 2S albumin; peptidase inhibitor; lectins.Practical Application: The study of anti-nutritional factors identification is very important because of its inactivation on food industry and it can also be used to avoid allergy due to them.

Resumo -Parâmetros genéticos estimados por meio de delineamentos genético-estatísticos considerando-se efeitos de populações e progênies são inexistentes para o pequizeiro (Caryocar brasiliense Camb.). O objetivo deste trabalho foi estimar parâmetros genéticos e avaliar a eficiência da seleção baseada em caracteres de crescimento em estádio precoce nesta espécie. O experimento foi instalado em janeiro de 2005, utilizando-se mudas de 31 matrizes originadas de duas procedências, em um delineamento em blocos ao acaso com seis repetições e cinco plantas por parcela, no município de Carbonita, MG. Nos anos de 2005 a 2008 avaliaram-se os caracteres: altura de planta (2005; 2006; 2007 e 2008), diâmetro do caule ao nível do solo (2006; 2007; 2008) e diâmetro da copa (2008). As estimativas da herdabilidade no sentido restrito em nível de indivíduo variaram de 0,15 a 0,50. As correlações genéticas e fenotípicas entre os caracteres nos diferentes anos foram positivas e em geral altamente significativas. Estimativas da eficiência de seleção obtidas pela expressão de Hamblin e Zimmermann variaram de médias a altas para todos os caracteres. Concluiu-se que, na hipótese de correlação significativa entre os caracteres avaliados e a produção de frutos, a seleção para produção de frutos, baseada em caracteres de crescimento, pode ser iniciada em estádio precoce. Palavras-chave -Caryocar brasiliense. Progênies. Eficiência de seleção. Melhoramento genético.Abstract -Genetic parameters estimated through statistical-genetic designs considering population and progeny effects are lacking for the pequi tree (Caryocar brasiliense Camb.). The aim of this study was to estimate genetic parameters and evaluate the efficiency of selection based on growth traits in the early stages. The experiment was carried out in Carbonita, Minas Gerais, Brazil, on January of 2005, using a randomized block design with 31 progenies, six replications and five plants per plot. From 2005 to 2008 the following traits were evaluated: plant height (in 2005; 2006; 2007 and 2008), stem diameter at ground level (in 2006; 2007; 2008) and crown diameter (in 2008). Estimates for narrow-sense heritability at the individual level varied from 0.15 to 0.50. The genetic and phenotypic correlations between characteristics in the different years were positive and generally highly significant. Estimates of the selection efficiency, obtained using the Hamblin and Zimmermann Expression, ranged from medium to high for all traits. It was concluded that under the premise of a significant correlation between these traits and fruit production, selection for fruit production based on growth traits could be started at an early stage.

“…In the popular medicine, it is used for the treatment of respiratory and ophtalmic problems, against bronchitis, colds, flus, and in tumors control (Almeida and Silva 1994). It is considered as an aphrodisiac; and its leaves are adstringent, also stimulating the bile production (Almeida and Silva 1994, Ribeiro 1996, Brandão et al 2002, Kerr et al 2007). The nut, besides being used in tannery, is tinctorial (Brandão et al 2002).…”

“…The small pharmacies and shamans of the villages and cities of these regions require about 3,000 people to remove the thorns left by the seed kernels at the palate of unaware eaters. This characteristic is the main flaw that eliminates the pequi from being cultivated at home and of being considered as market fruit (R. Gribel, unpublished data, Kerr et al 2007). …”

Caryocar brasiliense (pequi), is one of the main species at the biome of the Brazilian savannah due to its use in culinary, popular medicine, industry in general, and iron and steel industry. At São José do Xingu (MT), a tree of C. brasiliense without thorn at the endocarp was found, which enables the improvement of C. brasiliense not only for consumption but also to the high appreciation it already has. To detect the existing differences between the pequi with and without the thorn at the endocarp, RADP markers were used. The generated polymorphisms were cloned and sequenced in order to identify the sequences that are responsible for the fenotypical alteration. It was observed that the pequi without thorn is genetically isolated from the other populations of pequi with thorn at the endocarp, proving that this characteristic is related to the genetic divergence of the species. Analysis in BLASTn evidenced the similarity of the Dof1 genes of Zea mays to its gene of phosphinotricin acetyl transferase. In the analysis of BLASTx, the similarity was verified to the proteins responsible for the deficiency in ferric reductase 4, and catalase.

Pequi (Caryocar Brasiliense Camb.): informações preliminares sobre um pequi sem espinhos no caroço

Abstract: É relatado o achado de uma planta de pequi (Caryocar brasiliense Cambi) no Norte de Mato Grosso, sem espinhos no caroço (figuras 1 e 2). O pequi é a 3ª fruta mais consumida pelas populações do cerrado brasileiro e o seu único defeito é ter o caroço cheio de espinhos.
