Os frutos cítricos apresentam prolongado período pós-colheita, no entanto, devido à perda de água, após colhidos, perdem a firmeza e ficam com pouco brilho na casca. Face ao exposto, objetivou-se neste trabalho determinar os efeitos dos revestimentos na conservação pós-colheita da laranja 'Natal CNPMF 112' com utilização de extratos de própolis aquoso e alcoólico e a cera de carnaúba em condição refrigerada. Frutos da laranjeira 'Natal CNPMF 112', enxertada em limoeiro 'Cravo', foram tratados com cera de carnaúba (100%) e extratos de própolis alcoólico e aquoso (30%). O delineamento experimental foi inteiramente casualizado, com arranjo em parcelas subdivididas, sendo as parcelas constituídas pelos revestimentos mais a testemunha (água destilada), e as subparcelas pelo período de armazenamento (0, 10, 20 e 30 dias) a 12 ºC ± 2, com exceção para perda de massa, a qual foi avaliada a intervalos de três dias (0 a 30 dias). Avaliaram-se: perda de massa dos frutos, massa média dos frutos, sólidos solúveis, acidez titulável, ácido ascórbico, índice de maturação, pH e índice tecnológico. Conforme os resultados, observou-se que o extrato alcoólico de própolis promoveu menor perda de massa do fruto, bom índice de maturação e acidez equilibrada. As demais características não foram afetadas pelos revestimentos utilizados na conservação pós-colheita da laranja 'Natal CNPMF 112' refrigerada. Portanto, recomenda-se o extrato alcoólico de própolis para a conservação da laranja 'Natal CNPMF 112'.

The banana fruits of 'FHIA 18' have sensory properties like the 'Prata' ones. However, there is no information regarding to phosphorus (P) requirement of this hybrid and its effects on postharvest quality. This study aims to evaluate the physicochemical properties of 'FHIA 18' banana fruits submitted to different phosphorus levels under the edaphoclimatic conditions of the municipality of São Manuel, state of São Paulo, during three successive production cycles. Therefore, different levels of Phosphorus (0 [0%], 20 [50%)], 30 [75%], 40 [100%], 50 [125%] and 60 kg ha-1 year-1 P2O5 [150%]) were applied during three production cycles. A completely randomized design and split plot structure was used, the plots consisted of six phosphorus fertilizers doses and three production cycles (2014, 2015 and 2016) in sub plots. For unripe fruits, we evaluated the contents of dry matter, starch, total sugars, reducing sugars and phosphorus. For ripe fruits, we analyzed firmness, peel colour descriptors, total titratable acidity, total soluble solids, maturity index, total sugars and reducing sugars. Results showed that P fertilizer provided an increase in P content in unripe fruits until the application of 100% of the recommended dose; besides an increase in the reducing sugar contents until the application of 61% over the first production cycle. Results also indicated that applying lower phosphorus doses ( ? 100% of the recommended dose) promoted lower total titratable acidity and higher maturity index (52-53% of recommendation) in ripe fruits. Regardless of P2O5 dose, the contents of dry matter, starch and phosphorus increased in unripe fruits from first to third crop cycle, as well as the firmness, total soluble solids contents, maturity index and sugar content in ripe fruits.

Bananas are the world's most popular fruit. Nonetheless, a great part of the production is lost, mainly for insect and disease incidences. Thus, cover developing banana bunches is a promising physical protection method that will improve the visual quality of the fruits, especially the rapidly growing consumer demand for healthy fruits. In fact, bags serve as protective barrier, allowing the production of free fruit damage; consequently, lowering production costs by cutting crop losses, as well as avoiding chemical materials. There is a wide variety of bag types and colours, but also, there is a scarce literature on their efficiency. This study hence aimed to evaluate the influence of coloured polyethylene bags on yield, seasonality and plant health of the 'BRS Conquista' bananas in subtropical high-altitude growing conditions. Treatments therefore consisted of using white, black, red and blue polyethylene bags, besides control (uncovered). Then, bags were randomly distributed in five blocks, four plants per plot. After bunch harvest, the following evaluation were proceeded: agronomic yield, the interval between bunches cover and harvest, injuries caused by thrips and the incidence of anthracnose. Results indicated that banana bunch coverings did not interfere in bunch yield. Nevertheless, white and black bags reduced the interval between bunch covers and harvest, that is, 114 and 115 days, respectively. Furthermore, white and red bags reduced the damage caused by thrips in fruits; while white, red and blue bags decreased the anthracnose incidence. This study therefore recommends the use of white polyethylene bags to cover banana bunches of the cultivar BRS Conquista, since this bag colour showed highly efficiency in controlling thrips and anthracnose incidence, besides reducing the interval between bunch cover and harvest.

Figs consumption date back to the beginnings of civilization. Currently, consumers have become more demanding about quality of fruits, and figs are then highly indicated, since it is rich in nutrients, making them a great addition to a healthy diet. Although there is only one commercial fig cultivar that is commonly grown in Brazil, different cultivars should be considered for the diversification of fig production with regards to their yield and fruit quality. This research aimed at evaluating growth, yield, physicochemical characteristics and bioactive compounds of figs grown in Brazil. Then, four cultivars (Roxo de Valinhos, White Genova, PI-189 and Troyano) were studied to determine canopy volume, productive efficiency, soluble solids - SS, pH, titratable acidity - TA, SS/TA ratio, sugars, ascorbic acid, phenolic compounds, pigments and antioxidant activity. The cv. White Genova presented the highest canopy volume, while 'Roxo de Valinhos', 'PI-189' and 'Troyano' performed the greatest productive efficiency. The cvs. Roxo de Valinhos, White Genova and Troyano produced fruits with higher content of SS, reducing sugars and SS/TA ratio, while the fruits of 'PI-189' and 'Roxo de Valinhos' contained the highest levels of antioxidant activity. PCA enabled to differentiate the studied cultivars, which evidenced that PI-189 was the most different of all.
