“…On the 12th day, the control and the fruits treated with 120 mg L -1 presented the highest content of total anthocyanins, reaching 6.80 and 6.31 mg.100 g -1 FW respectively, while the fruits treated with 160 and 180 mg L -1 of GA 3 showed a reduction in the content of total anthocyanins, reaching 5.60 and 5.45 mg 100 g -1 FW, respectively. In this work, the application of 120 mg L -1 of GA 3 is associated with an increase in the a* values ( Figure 1B) and accumulation of anthocyanins, which, according to Souza et al (2014), make this compound the main polyphenol present in the ripe acerola. Miller and Rice-Evans (1997) reported that phenolics such as anthocyanins protect vitamin C from degradation.…”

“…Conversely, Rosso and Mercadante (2007) suggested that anthocyanins can condense with ascorbic acid leading to a faster degradation of both compounds. Souza et al (2014) evaluating anthocyanin content in acerola clones, observed that quercetin-3-ramnoside is the most abundant yellow flavonoid and that the content is dependent on the cultivar. In this study, yellow flavonoids significantly increased in amount during storage in association with the color change observed in fruits, however, no significant effect of GA 3 was observed between treatments ( Figure 4C).…”

“…The selection of clones is the most efficient way to supply the immediate demand for genotypes with higher productivity and vitamin C content. The BRS 236 clone or also called "cherry" produced 49 tons of fruits per hectare with high vitamin C content (1854 mg 100 g -1 ) if compared with other clones such as Florida Sweet (862 mg 100 g -1 ), Flor Branca (1104 mg 100 g -1 ) and BRS 366 (1363 mg 100 g -1 ) (SOUZA et al, 2014). The acerola is a fruit with climacteric respiratory pattern, that which undergoes various transformations during the maturation, ripening and senescence processes (CHITARRA; CHITARRA, 2005), highlighting the degradation of chlorophyll, carotenoids synthesis and loss of vitamin C. In this way, the acerola has a short postharvest with losses of 40%, due to their high respiratory rate and fragile structure, being necessary the use of processing techniques capable to prolong the conservation of the fruits, extending the postharvest (MATSUURA, 2001).…”

ABSTRACT-The goal of this study was study the postharvest quality of acerola clone BRS 236 (Malpighia emarginata D.C.) which was harvested at physiological maturity and submitted to four treatments under immersion during 5 minutes at 25 °C, which are: control (water), 60 mg L . After treatment the fruits were packed in polystyrene trays and placed with polyethylene film and then stored at 10 ± 2 °C and 85 ± 5% RH for 12 days. Were analyzed in three days intervals (0, 3, 6, 9 and 12 days): skin color, firmness, pH, titratable acidity, soluble solids, SS/TA ratio, vitamin C and yellow flavonoids. Vitamin C, anthocyanins and yellow flavonoids were not influenced by treatments with GA 3 at the end of 12-day of cold storage at 10 ºC. The exogenous application of 120 mg L -1 of GA 3 resulted in retention of red color and content of anthocyanins of acerola fruits BRS 236 clone 12-day storage at 10 °C. Index Terms: Color; Storage; Firmness; Vitamin C; Gibberellin. QUALIDADE PÓS-COLHEITA DE ACEROLAS (Malpighia emarginata)TRATADAS COM ÁCIDO GIBERÉLICO E ARMAZENADAS SOB REFRIGERAÇÃO RESUMO-Objetivou-se com este trabalho estudar a qualidade pós-colheita de acerolas do clone BRS 236 (Malpighia emarginata D.C.), colhidas na maturidade fisiológica e submetidas a quatro tratamentos com ácido giberélico (GA 3 ) por imersão durante 5 minutos a 25 °C, sendo eles: controle (água), 60 mg L -1 ; 120 mg L -1 e 180 mg L -1 . Após o tratamento os frutos foram colocados em bandejas de isopor e cobertos com filme de polietileno, e em seguida armazenados à temperatura de 10±2 ºC, com umidade relativa de 85±5%, durante 12 dias. Foram analisadas em intervalo de três dias (0, 3, 6, 9 e 12 dias): coloração da casca, firmeza, pH, acidez total titulável, sólidos solúveis, relação SS/AT, vitamina C e flavonóides amarelos. Compostos bioativos como a vitamina C e flavonóides não foram influenciados pelos tratamentos com GA 3 ao final de 12 dias de armazenamento a 10 ºC. A aplicação exógena de 120 mg L -1 de GA 3 resultou em maior retenção da cor e conteúdo de antocianinas em acerolas do clone BRS 236 durante 12 dias de armazenamento a 10 ºC. Termos para indexação: Cor; Armazenamento; Firmeza; Vitamina C; Giberelinas 1 (Paper 017-16).

Objective: The work was aimed to study the changes in the level of phenols and flavonoids during fruit development and its antioxidant potential. The number of experiments conducted was twenty for each case. Polyphenols at different ontological stages may help producers and food technologists to identify which cultivar and/or maturity stage are most adequate for their need. Results:The total phenolic contents varied from 30.35 to 2.26 mg chlorogenic acid equivalents/g dry weight (DW), and the total flavonoid contents ranged from 0.683 to 3.37 mg rutin equivalents/g DW. Total phenolics showed an initial increase and subsequently decreased during development. In contrast, flavonoids increased from stage I to VI. Antioxidant assays showed varied patterns of inhibition. Conclusion:Significant correlations were observed between antioxidant capacities and total phenolic and flavonoid contents.

“…Estas dos especies dan frutos de consumo regional, que por su aroma, sabor, contenido nutrimental, antioxidantes (SILVA et al, 2006;MEZADRI et al, 2008;SOUZA et al, 2014) y propiedades nutracéuticas (GORINSTEI et al, 2011) tienen calidad de exportación; sin embargo, en nuestro país poco se conocen; B. crassifolia está más domesticada y es en la que se reportan algunos estudios enfocados a características morfológicas de frutos, semillas, hojas, tallos y germinación (MARTÍNEZ-MORENO et al, 2010;MALDONADO-PERALTA et al, 2016).…”

RESUMEN -El nanche es un frutal que produce gran parte del año y del que poco se conoce sobre su propagación asexual; por ello, el objetivo de esta investigación fue evaluar el efecto de sustratos, enraizadores y tipo de estacas en la propagacion vegativa de nanche rojo, rosa y amarillo, recolectadas en Santa María Zoquitlán, Oaxaca, México. Se hipotetiza que el uso de reguladores del crecimiento incrementa el enraizamiento y sobrevivencia de estacas. La investigación se realizó en el Colegio de Postgraduados, Campus Montecillo. El experimento 1 fue en primavera-verano, utilizando estacas de 16 cm, 384 apicales y sub-apicales sin hojas, de cada tipo de nanche. Se llenaron charolas de 5 L con turba, agrolita + turba y arena + fibra de coco (3:1 v/v). Las estacas se impregnaron 5 cm de la base con AIB a 3,000, 6,000 y 10,000 ppm, en presentación en polvo y se compararon con un testigo tratado sin AIB. El experimento 2 fue en otoño-invierno, utilizando 108 estacas sub-apicales con tres pares de hojas, de cada tipo de nanche. Como sustrato se usó arena + turba (3:1 v/v) y AIB a 3,000 y 6,000 ppm, un producto comercial Biozyme *TF®, en presentación líquida y un testigo. Las charolas plantadas se cubrieron con bolsas de plástico transparente. El diseño experimental fue en BCA. Se evaluó el porcentaje de sobrevivencia, de brotación y enraizamiento. Los valores se transformaron usando la función arcoseno, se realizó un ANOVA y separación de medias mediante pruebas de Tukey. Las estacas con hojas plantadas en otoño (experimento 2) presentaron mejor sobrevivencia y brotación. El AIB a 6,000 ppm mejoró la brotación de las estacas apicales y el enraizamiento en sub-apicales; el Biozyme *TF® no se recomienda para el enraizamiento. El nanche rojo obtuvo mejor enraizamiento que el rosa y amarillo. Términos para indexación: propagación asexual, auxinas, nanche rojo, nanche rosa, nanche amarillo.

RESUMO -O nanche é uma frutífera que produz grande parte do ano e pouco se sabe sobre sua propagação assexuada; portanto, o objetivo deste trabalho foi avaliar o efeito de substratos, enraizamento em estacas de nanche vermelho, rosa e amarelo, coletadas em Santa Maria Zoquitlán Oaxaca, México. Supõe-se que a utilização de reguladores de crescimento aumentará o enraizamento e a sobrevivencia das estacas caulinares. A pesquisa foi realizada no Colégio de Pós-Graduação, Campus Montecillo. O primeiro experimento foi realizado na primavera-verão, utilizando estacas de 16 cm, 384 apicais e sub-apicais sem folhas, de cada tipo de nanche. Bandejas de 5L foram preenchidas com esfagno, perlita + esfagno e areia + fibra de coco (3:1 v/v). Aproximadamente 5 cm da base das estacas foram impregnados com AIB a 3.000, 6.000 e 10.000 ppm, na forma de talco e um controle. O segundo experimento foi realizado em outono-inverno, usando 108 estacas lenhosas com 3 pares de folhas, de cada nanche. Como substrato foi usado ...
