Qualidade de framboesas sem cobertura ou cobertas sobre o dossel e em diferentes espaçamentos

Abstract

, MaTTeUS heBeRTh RiBeiRo do Valle 5 resumo -a framboesa é uma pequena fruta de grande importância econômica, que contém numerosos compostos fenólicos, com potenciais benéficos à saúde; porém, quando cultivada em regiões subtropicais, possui problemas com podridões pós-colheita. o objetivo do presente trabalho foi determinar a qualidade de framboesas cultivadas sem cobertura ou com o dossel coberto com cobertura plástica e em diferentes espaçamentos (3 x 0,50 m e 3 x 0,25 m). Foram avaliadas: a coloração dos frutos, a quantidade de antocianinas, vitamina C, cinzas, umidade, sólidos solúveis totais, açúcares, acidez, firmeza, incidência de ferrugem nos frutos e a composição mineral (nitrogênio, fósforo, potássio, cálcio, magnésio, enxofre, boro, cobre, manganês, zinco e ferro). Ao final, observou-se que cultivo com espaçamento 3 x 0,25 m e cobertas com cobertura plástica aumentou a qualidade das framboesas. termos para Indexação: Rubus idaeus l., Pucciniastrum americanum (Farl.) arth., qualidade de frutos. QualIty raspBerrIes WIth and WIthout plastIc coverInG over the canopy In dIFFerent spacInGaBstract -Raspberry is an economically important berry crop; its fruit contains numerous phenolic compounds with potential health benefits. But when grown in subtropical regions has problems with post-harvest decay. The objective of this study was to verify quality raspberries with and without plastic covering over the canopy in different spacing (3 x 0.50 m e 3 x 0.25 m). Were evaluated: assessed the color of the fruit, the amount of anthocyanins, Vitamin C, ash, moisture, soluble solids, sugars, acidity, firmness, rust incidence in fruits and mineral composition (nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, copper, manganese, zinc and iron). at the end it was observed that plants on 3 x 0.25 m spacing and with plastic covering over the canopy increase the quality of raspberries.

PLASTIC COVERING, PLANTING DENSITY, AND PRUNNING IN THE PRODUCTION OF CAPE GOOSEBERRY ( Physalis peruviana L.) IN SUBTROPICAL REGION

“…The fertilizing recommendation was carried out according to the tomato plant cultivation practices, with 10 t ha -1 productivity expectation (MUNIZ et al, 2015). All plants were irrigated with the use of drippers spaced at every 30 cm, with a flow rate of 1.7 liters per hour in each dripper (CURI et al, 2014).…”

“…Thus, it is expected to obtain an increase in the orchards productivity when decreasing the spacing between the plants. Curi et al (2014) found some advantages in relation to the quality of raspberries that were produced in thickened spacing in Southern Minas Gerais state.…”

“…Fruit trees cultivation under plastic covering is a measure that might benefit the quality of fruits as well as reduce the use of chemicals in the orchard (PEDRO JÚNIOR;HERNANDES;ROLIM, 2011, CURI et al, 2014, MARO et al, 2014; in addition to preventing hail detrimental effects and excessive wind (HERNANDES et al, 2013). Based on Comiran et al (2012), this measure has already been established in vineyards to prevent the effects of excessive rainfall over the plant canopy, especially during fruit maturation, helping to maintain the quality of grapes.…”

Armazenamento a frio e aplicação de reguladores vegetais no enraizamento de estacas radiculares e caulinares de framboeseira

“…Dentre as opções de espécies frutíferas do gênero Rubus com boas perspectivas de comercialização e utilização na agroindústria familiar, destaca-se a framboeseira (Rubus idaeus L.), que é uma espécie ainda pouco cultivada no Brasil e que tem despertado grande interesse por diversos produtores (SILVA et al, 2012;CURI et al, 2014;SOUZA et al, 2014a;SOUZA et al, 2014b).…”

Blackberry and redberry production in crop and intercrop in Pouso Alegre, southern Minas Gerais, Brazil

“…The main fruits in this group are strawberries, raspberries, blackberries and blueberries (CURI et al, 2014;MOURA et al, 2012;TIBERTI et al, 2015 In the south of Minas Gerais, strawberry production is consolidated and there is an increasing cultivation of other small fruits, especially blackberries, as an alternative for family farming, since it employs labor and can increase income (CAMPAGNOLO & PIO, 2012a;PATTO et al, 2013;CURI et al, 2015a).…”
