| ABSTRACT The objective of this study was to evaluate the quality of ‘Ubá’ mango fruit submitted to mechanical damage. The fruits were harvested in the 2012/2013 harvest, and let to drop once on a flat, hard surface, simulating the harvesting process of ‘Ubá’ mango, which is to drop all the fruits of a plant when they are physiologically mature. Treatments consisted of different drop heights (zero, one, two, three, four and five meters), totaling six treatments. After the fall, the fruits were submitted to ripening, and then evaluated for fresh mass loss (FML), presence of external lesions (PEL), presence of internal lesions (PIL), soluble solids content (SS),titratable acidity (TA), pH, SS/TA ratio and vitamin C. There was no difference between fresh... |

| ABSTRACT The aim of this study was to quantify and compare the levels of carbohydrates and phenolic compounds and the antioxidant activity in the pulp and peel of 15 banana cultivars in two ripening stages. Four bunches per cultivar were harvested in the pre-climacteric stage, six fruits were used by sample unit. Fruits were analyzed in the pre-climacteric stage and after ripening. Total, reducing and non-reducing soluble sugars, starch, phenolic compounds and antioxidant activity were evaluated. Cultivar and ripening stage influenced all characteristics analyzed. Unripe pulp and peel had small percentage of sugar, but high percentage of starch, especially ‘Terrinha’ and ‘Marmelo’ cultivars. AAB and ABB cultivars presented the highest percentages of... |

| A jabuticaba tem grande aceitação para consumo "in natura". Entretanto, é altamente perecível, com pequena conservação pós-colheita. Acredita-se que o cálcio seja capaz de retardar a senescência e manter a firmeza dos frutos. O objetivo do presente trabalho foi de ampliar o período de conservação pós-colheita de jabuticabas, por meio de sua imersão em solução de CaCl2. Os frutos foram colhidos completamente maduros em pomar da UFV, imersos em solução de CaCl2 40 g.L-1 por 0; 5; 10; 20; 40 e 60 minutos e mantidos à temperatura e umidade relativa ambientes por seis dias. Maiores tempos de imersão resultaram em maior retenção de firmeza dos frutos, embora sem afetar a perda de matéria fresca dos mesmos. Houve, em todos os tempos de imersão usados, redução da... |

| The aim of the study was to assess the influence of season and different substrates on rooting of air layers of lychee (Litchi chinensisSonn.) for the production of seedlings to ensure the formation of uniform and productive orchards. Air layers were done in plants of the Bengal cultivar using leafy and healthy woody branches, with about 0.010 to 0.015 m in diameter, in which were performed complete girdling with 0.020 m wide at a distance of 0.30 to 0.40 m below the apex. Then the branches were wrapped in moistened substrate. The layering was made at six times of theyear (January, March, May, July, September and November) and two substrates were used (coconut fiber and sphagnum) in a 6 x 2 factorial design in a randomized block with ten replicates. After... |

| ABSTRACT This study aimed to evaluate some changes in the metabolism of papaya fruits submitted to damage by impact, abrasion and compression. Injuries were caused in two areas of 15 cm2 each; in diametrically opposite positions in the equatorial region of ‘Improved Sunrise Solo Line 72/12’ papaya fruits in ripening stage 3 (fruits with 25-40% of yellow skin). After damage, fruits were stored at 15 ± 1 °C and 85 ± 5% RH, and samples were taken at intervals of two days to evaluate skin color index, incidence of diseases, loss of fresh weight, leak of solutes, pulp firmness, soluble solids content and pectinmethylesterase and polygalacturonase activities. The respiratory rate was measured at intervals of 4, 8, 12, 24, 48 and 72 hours after damage. The... |

| ABSTRACT The aim of this study was to evaluate 12 rootstock varieties on the development and quality of ‘Tahiti’ acid lime fruits cultivated in the municipality of Jaíba, MG. Seedlings were planted in an experimental orchard in November 2008, using 8 x 5 meters spacing and drip irrigation. The experiment was conducted using a scion cultivar (Tahiti acid lime, IAC-5 cultivar) and the following 12 rootstocks: ‘Rangpur’ lime, ‘Troyer’ citrange, ‘Carrizo’ citrange, 1707 hybrid (Rangpur lime x Swingle trifoliate), 1710 and 1697 citrandarins, 1708citradia, ‘Swingle’ citrumelo, ‘Cleopatra’ and ‘Sunki’ mandarins, ‘Volkamer’ lemon, and ‘Limeira’ trifoliate. A randomized block design with five replicates and three trees per plot was used. Trunk diameter of both... |

| Dois cruzamentos envolvendo três linhagens de sorgo (Sorghum bicolor L. Moench): BR 007A x BR 501R e BR 008A x BR 501R originaram dois híbridos forrageiros: BR 601 e BR 602. Estes, em conjunto com suas gerações avançadas por autofecundação F2 e F3, constituindo nove genótipos, foram avaliados em duas épocas de plantio (normal e sucessão), em diversos caracteres de rendimento e qualidade da forragem, obtendo-se as estimativas dos efeitos gênicos, heterose média, heterobeltiose e depressão endogâmica nas gerações F2 e F3. Os resultados permitiram as seguintes conclusões: (a) no plantio em sucessão, comparativamente ao normal, os híbridos forrageiros apresentaram menor altura de planta, florescimento precoce, redução na matéria verde e no rendimento da massa... |
