The number of seeds is not a good indicator to the ratio with fruit mass; however, the mass of thousand seeds is a good indicator.Some accessions have high content of soluble solids, but most of the fruits showed high acidity. The cambuci fruit is an excellent source of vitamin C. The accession fruits have green color, persisting an opaque hue in ripe fruits.

ABSTRACT. The objective of this study was to evaluate the production of seedlings of Physalis L. species under different-colored shade nets. Four shade nets individually stained white, blue, red and black, all with 50% shading, were used in this study, and an additional treatment (control) was used in which seedlings were grown in full sun. The study examined four species of Physalis, namely, P. peruviana, P. pubescens, P. minima and P. ixocarpa. The experiment followed a randomized block design with three blocks and 25 seeds per plot. The species were sown in styrofoam trays. Germination was monitored daily to calculate the Emergency Velocity Index (EVI) and stabilize the overall percentage of emergence. Height, stem diameter, number of leaves, leaf area index and dry mass of seedlings were assessed at 50 days after sowing. The study found that these species react differently to changes in the light spectrum. Seedlings of P. peruviana should be grown under a white or red shade net; of P. pubescens under a white or black shade net; of P. minima under a white, red or black shade net; and of P. ixocarpa under a white shade net. For all species, 50% shade should be used.Keywords: Physalis L., sexual propagation, seedling morphology, light spectrum. Produção de mudas de espécies de Physalis cultivadas sob diferentes colorações de telas fotoconversorasRESUMO. Objetivou-se com o presente trabalho, avaliar a produção de mudas de espécies pertencentes ao gênero Physalis L. sob telas fotoconversoras de diferentes colorações. Foram utilizadas quatro telas fotoconversoras, nas colorações branca, azul, vermelha e preta, todas com 50% de sombreamento, além de um tratamento a pleno sol (controle), e quatro espécies de Physalis: P. peruviana, P. pubescens, P. minima e P. ixocarpa.

The objective of this work was to evaluate the bioactive compounds, antioxidant activity, and physicochemical characteristics of dovyalis fruit to obtain technological knowledge about this fruit when grown under the conditions found in the municipality of Marechal Cândido Rondon, Paraná State, Brazil. Dovyalis fruits from the State University of Western Parana, which was established in 2012, were harvested in March 2016. Dovyalis fruits were collected from several plants and were divided among three lots. After the harvest, were immediately taken to the Post-Harvest Laboratory for evaluation of the antioxidant activity by the DPPH, ABTS and FRAP methods. The physicochemical characteristics of the fruits and the total phenolic compounds, flavonoids, ascorbic acid, anthocyanins, respiration, and fruit color were evaluated. The experimental design was completely randomized, with the study containing three groups and three replicates per group. Dovyalis fruits present high antioxidant capacity and are characterized as acidic fruits, due to the high FRAP activity. Dovyalis fruits have a very attractive color and high acidity, which makes them appropriate for processing. Regarding the antioxidant activity present in the fruit, the most bioactive components are flavonoids and anthocyanins. High ascorbic acid content was observed in mature dovyalis fruits. Dovyalis fruits are considered climacteric.

Postharvest and fruit production of cape gooseberry in Minas Gerais State, BrazilPhysalis sp., is a genus of plant popularly known as cape gooseberry. The enlarged calyx that surrounds and protects the fruit against herbivores and weather characterizes the genus, which contains over than one hundred species belonging to the Solanaceae family. The bittersweet fruits are widely used in cooking, and can also be processed into jellies, jams and liqueurs, or consumed raw. The fruits present high content of vitamin C and antioxidants, and therefore, contain numerous medicinal properties. This study aimed to evaluate the productivity of cape gooseberry in southern Minas Gerais State, and to observe the aspects of its postharvest. The experiments related to the productivity were installed at the Experimental Farm of EPAMIG, in Maria da Fé, Minas Gerais State, Brazil, while other experiments on postharvest were carried out in the Laboratory of Food Technology of UNIOESTE. To evaluate the productivity, the Conservação pós-colheita de fisális e desempenho produtivo em condições edafoclimáticas de Minas GeraisO Physalis sp., popularmente conhecido como fisális, é um gênero com mais de 100 espécies, pertencente à família Solanaceae, caracterizado pelo cálice concrescido, que envolve e protege o fruto contra herbívoros e intempéries. Os frutos, de sabor agridoce, são muito utilizados na culinária, podendo também ser processados em geleias, doces e licores, consumidos in natura, por seu alto teor de vitamina C e antioxidantes, além de apresentarem inúmeras propriedades medicinais. Este trabalho objetivou analisar a produtividade de fisális na região sul do Estado de Minas Gerais e observar aspectos de sua conservação pós-colheita. Os experimentos relacionados com a produtividade foram instalados na Fazenda Experimental da EPAMIG, em Maria da Fé, MG, e os demais experimentos, relacionados com a conservação pós-colheita, instalados no Laboratório de Tecnologia de Alimentos da UNIOESTE. Para avaliação da produtividade, instalou-se experimento contendo três blocos, com quatro plantas, e, para avaliação pós-colheita, foram utilizadas três repetições de cinco frutos, armazenados em câmara controlada tipo B.O.D, sem atmosfera modificada, por 28 dias, à temperatura de 5ºC, e avaliados no momento da instalação, aos 7, 14, 21 e 28 dias. Foram avaliados diâmetros longitudinal e transversal (mm), peso médio do fruto (g), com e sem cálice, peso total da colheita (g) e teor de sólidos solúveis totais.

observed that P. peruviana and P. pubescens have more acid fruits, and P. minima shows vitamin C content higher than the other species. In general, fruits of P. peruviana and P. pubescens have better quality when grown in white, blue or black shade net; fruits of P. minima are physicochemically superior when produced under full sun or under white or blue shade net; finally, fruits of P. ixocarpa have low quality when produced under black net.

Faced with the need for greater knowledge of the different physalis species, the aim of this study was to characterize different Native American physalis species (Physalis peruviana L., Physalis pubescens L., Physalis angulata L., Physalis mínimos L. and Physalis ixocarpa Brot) as to their physicochemical characteristics, bioactive compounds and antioxidant activity. Besides that, in order to increase their use and add even more value to this fruit, we also evaluate the influence of these different species on the physicochemical, rheological and sensory characteristics of physalis jelly. In addition, this study evaluated the sensory acceptance of the combination of physalis jellies obtained from different species with brie-type cheese. The Peruviana, Pubences and Angulata, are highlighted for being the nutritionally richest species, with the highest levels of phenolic compounds, vitamin C and antioxidant. Moreover, they stand out for originating the most widely sensory accepted jellies, either in pure form or in combination with brie-type cheese.Keywords: Physalis L.; different species; characterization; jelly processing; harmonization. Practical Aplications: It was possible to verify which physalis are the nutritionally richest species and which species are more suitable for jelly processing.

Article AbstractNowadays the semihardwood cuttings of olive is the most used method to produce seedlings of this specie; however, it is necessary to improve the efficiency of this method to enable the intensive exploitation of this fruit crop and reduce the seedling production costs. Thus, two experiments were conducted concurrently in sand bed, under a canvased shelter of the State University of Western Paraná (Brazil) to evaluate the number and average length of roots per cuttings, the percentage of rooted cuttings, cuttings with callus and dead cuttings. In the first experiment cuttings of olive cultivars Arbequina, Maria da Fé and clone 2 were treated with IBA (3.0 g L -1 ) associated with calcium concentration at 0.0; 0.25; 0.50 and 1.0 mmol L -1 , implanted in a completely randomized design in a split plot design, with four replications containing ten cutting each, under intermittent mist. For this experiment the Arbequina cultivar presented the highest average number of roots per cutting and the highest percentage of rooted cuttings, but Maria da Fé cultivar promoted the highest average of cuttings with callus. In the second experiment Clone 2 cuttings were submitted to calcium (0.5 mmol L -1 ) and IBA (3.0 g L -1 ), and substrate inoculation with Azospirillum brasilense bacterium, implanted in a completely randomized design containing three replications of ten cuttings each. In this experiment, the highest percentage of rooted cuttings was obtained for IBA (3.0 g L -1 ) + A. brasilense.
