“…The occurrence of inadequate pollination in some years may result in a decrease in nut yield and quality (CONNER, 2012). The pollination of pecan is predominantly carried out by the wind (anemophilous) and is effective up to 49 meters between plants, with a substantial reduction in fruiting in larger spacing (CONNER, 2011;WELLS, 2017).…”

“…Commercial orchards must be composed of at least two pollinator cultivars, but ideally from three to four (CONNER, 2012), aiming to increase the overlapping period of pollen dehiscence and stigma receptivity (WOOD, 1996). Concerning the Southern region of Brazil, there is only one study that has assessed the period of pollination and stigma receptivity of different pecan cultivars, which was conducted by BARACUHY (1980) (Figure 1), in the town of Cachoeira do Sul (RS).…”

“…Presently, people are looking to consume more natural foods, on account of the increase of the population's per capita income, and especially, due to the fruits nutraceutical effects. Among the natural foods, pecans are highlighted for their beneficial health effects, since they have phenolic compounds, mono and polyunsaturated fatty acids, phytosterols, tocopherols and micronutrients that reduce the risk of diseases (DOMÍNGUEZ-AVILA et al, 2015). According to EAGAPPAN & SASIKUMAR (2014), a regular consumption of nuts has been associated with several health benefits, protecting from oxidative stress, reducing LDL (bad) cholesterol, beyond their anticancer, antiinflammatory, and antidiabetic benefits, preventing chronic diseases.…”

Given the increasing investment in the pecan production in southern Brazil, it becomes necessary researches, assisting in solve problems and proposition of technical and methodology to enhance this production chain. Thus, the present review aimed to survey the existing information about the culture, both on the world and the Brazilian scene. Issues related to botany, climate and soil requirements, alignment and planting density, cultivars, pests and diseases, among other technical aspects of this culture will be addressed. Pecan nut presents nutraceutical properties that are beneficial to human health, which has increased its demand from consumers. However, there are few research results with pecan nut in Brazil and there are many gaps in scientific knowledge about this culture, especially as regards the management of pests and diseases control, irrigation and nutrition, in Brazilian conditions.

ResumenIntroducción: la Lecythis pisonis Cambess es conocida popularmente en Brasil como "castaña de sapucaia". Estudios de su composición química revelaron que esta castaña es una excelente fuente de minerales antioxidantes y de lípidos esenciales. Objetivo: evaluar los efectos antioxidantes y anti infl amatorios en el tejido cerebral de ratones Wistar. Material y métodos: los animales fueron distribuidos aleatoriamente en cuatro grupos experimentales (n = 6) totalizando 48 ratones. Los tratamientos fueron conducidos por un periodo de 14 a 28 días con dietas estándar AIN-93G y de cafetería con castaña de sapucaia. La expresión génica de los marcadores TNF-α, NFkB, ZnSOD y HSP-72 fue determinada por la reacción en cadena de la polimerasa cuantitativa tras transcripción inversa (qPCR). La actividad antioxidante también fue verifi cada por la determinación de las especies reactivas del ácido tiobarbitúrico (TBARS) y por mensuración de la actividad de la enzima superoxido dismutasa. Resultados: la expresión génica de los marcadores infl amatorios NFkB (p65) y TNF-α fue menor para los grupos de ratones que consumieron las dietas enriquecidas con sapucaia con diferencia signifi cativa por el test de Tukey (p < 0,05). La proteína de choque térmico HSP-72 y la enzima ZnSOD presentaron aumento de la expresión génica con diferencia estadística signifi cativa (p < 0,05) para ambos grupos que consumieron sapucaia en sus dietas. Conclusión: las propiedades nutricionales de la castaña de sapucaia ejercieron importante actividad neuroprotectora por modular la actividad antioxidante y el proceso infl amatorio en los tejidos cerebrales de los animales evaluados. AbstractBackground: Lecythis pisonis Cambess is commonly known as "castanha de sapucaia" in Brazil. Chemical composition studies revealed that this nut is an excellent source of anti-oxidant minerals and of essential lipids.Objective: The aim of the present study is to assess the anti-oxidant and anti-infl ammatory effect of Lecythis pisonis Cambess on the brain tissue of Wistar rats. Material and methods:The animals were divided in four experimental groups (n = 6), total of forty-eight rats. Treatments included the standard diet (AIN-93G) and high-fat food, supplemented with Sapucaia nut from 14 to 28 days. The gene expression markers TNF-α, NFkB, ZnSOD and HSP-72 were defi ned through reverse transcriptase polymerase chain reaction (rtPCR). The anti-oxidant effect was assessed through the thiobarbituric acid-reactive substances (TBARS) and the measurement of the activity performed by superoxide dismutase enzymes. Results: Accordingly, the gene expression of the infl ammatory markers NFkB (p65) and TNF-α was lower in rats fed on diets supplemented with "sapucaia", and they presented signifi cant difference in the Tukey test (p < 0.05). The heat-shock HSP-72 protein and the ZnSOD enzyme raised the gene expression and showed signifi cant statistical difference (p < 0.05) in both groups fed on Sapucaia nut-based diet. Conclusion: Thus, the nutritional properties of the Sa...

Tree nut oils are primarily composed of triacylglycerols, but also contain diacylglycerols (DAG), monoacylglycerols (MAG), free fatty acids (FFA), and other minor components, including natural antioxidants and fat‐soluble vitamins. The chemical composition of edible fats and oils largely determines their stability, quality, nutritional value, sensory properties, and potential health effects. Generally, the monounsaturated fatty acids (MUFA), predominantly oleic acid, are the major fatty acids present in tree nuts oil, followed by polyunsaturated fatty acids (PUFA) and small amounts of saturated lipids. Besides, tree nut oils contain abundant bioactive components including phytosterols, carotenoids, tocols, phospholipids, and sphingolipids. And as the major antioxidants in tree nut oil, the content of carotenoids and tocols remarkably affects the oil oxidative stability, as well as their degree of unsaturation and pigment content. Tree nuts have long been considered to be an important component of the Mediterranean diet. Their by‐products, especially defatted meals, skins, and hulls, may also be considered as excellent sources of protein and phytochemicals. Epidemiological evidence indicates that consumption of whole tree nuts may exert antioxidative stress, anti‐inflammatory, anti‐obesity, anti‐diabetes, and cardioprotective effects in animal or human body. Recent investigations have also shown that dietary consumption of either whole tree nuts, oils or polyphenol extract has beneficial effects on animal or human body, which implies that both the lipid components in oil and phenolics in defatted meal are responsible for the health‐enhanced results of tree nuts fed. In this article, the specific chemical composition, oxidative stability, and potential health effects of nine commercial tree nut oils (almond oil, hazelnut oil, pecan oil, walnut oil, pistachio oil, Brazil nut oil, pine nut oil, cashew nut oil, and macadamia nut oil) are summarized. In addition, the major amino acids profile, phenolic constituent, and health effects of tree nut by‐products are also presented.
