          Abstract

          ABSTRACT: The cultivation of mulberry ( Rubus sp.) is highly disseminated in cold climates, but some cultivars adapt to warm weather environments. The objective of the present study was to evaluate the production of blackberry and redberry in season and off season in Pouso Alegre, south of Minas Gerais. The experimental design was a randomized block, with twelve cultivars ('Arapaho', 'Xavante', 'Brazos', 'Tupy' 'Comanche', 'Choctaw', 'Guarani', 'Caingangue', 'Cherokee', 'Chicasaw' and 'Clone' and a redberry, three blocks and an experimental unit of four plants with a spacing of 0.5x3.0m and a total density of 6,666 plants per hectare. Conventional pruning was performed to produce the crop (October-December) and for off-season production (April-July). In 'Brazos' there was increased production in the two seasons evaluated against other mulberry trees, conversely, in the off season, there was a positive effect of pruning carried out in January only in 'Tupy', 'Choctaw', 'Comanche' and 'Clone', with 'Tupy' presenting the highest productivity off season. In 'Brazos' and 'Tupy' there was the best balance between soluble solids and acidity in the crop and red berry in season. 'Brazos' and 'Cherokee' had the highest average content of total sugars. Due to the lack of supply of fruit, pruning mulberry trees in January is an alternative to increase the income of family-based farms.

          RESUMO: O cultivo da amoreira ( Rubus sp.) está amplamente expandido em regiões de clima frio, entretanto algumas cultivares se adaptam em ambientes de clima ameno. Objetivou-se com o presente trabalho avaliar a produção de amoreira-preta e amoreira-vermelha na safra e entressafra em Pouso Alegre, sul de Minas Gerais. O delineamento experimental utilizado foi em blocos casualizados, com doze cultivares ('Arapaho', 'Xavante', 'Brazos', 'Tupy' 'Comanche', 'Choctaw', 'Guarani', 'Caingangue', 'Cherokee', 'Chicasaw', 'Clone' e uma amoreira-vermelha), três blocos e unidade experimental de quatro plantas, espaçadas a 0,5x3,0m, totalizando uma densidade de 6.666 plantas por hectare. Visando à produção na safra (outubro a dezembro) e entressafra (abril a julho), foram realizadas, nos meses de janeiro e julho, as podas convencionais. Em 'Brazos', verificou-se maior produção nas duas safras avaliadas em comparação com as demais amoreiras, já na entressafra, apenas em 'Tupy', 'Choctaw', 'Comanche' e 'Clone' verificou-se efeito positivo da poda realizada em janeiro e produziram frutos "fora de época", sendo em 'Tupy' a maior produtividade na entressafra. Na 'Brazos' e 'Tupy', verificou-se o melhor equilíbrio entre os sólidos solúveis e a acidez na safra e amora-vermelha na entressafra. 'Brazos' e 'Cherokee' obtiveram teor médio de açúcares totais superiores. Devido à inexistência da oferta de frutos de amoreira, a poda realizada em janeiro se torna alternativa para o aumento da renda dos agricultores de base familiar.

          Determination of the bioactive compounds, antioxidant activity and chemical composition of Brazilian blackberry, red raspberry, strawberry, blueberry and sweet cherry fruits.

          This study aimed to evaluate the chemical composition, identify the bioactive compounds and measure the antioxidant activity present in blackberry, red raspberry, strawberry, sweet cherry and blueberry fruits produced in the subtropical areas of Brazil and to verify that the chemical properties of these fruit are similar when compared to the temperate production zones. Compared with berries and cherries grown in temperate climates, the centesimal composition and physical chemical characteristics found in the Brazilian berries and cherries are in agreement with data from the literature. For the mineral composition, the analyzed fruits presented lower concentrations of P, K, Ca, Mg and Zn and higher levels of Fe. The values found for the bioactive compounds generally fit the ranges reported in the literature with minor differences. The greatest difference was found in relation to ascorbic acid, as all fruits analyzed showed levels well above those found in the literature.
