“…The development period of the panicle varied with the cultivar and was 45 days for 'Keitt'; 50 days to 'Palmer' and 63 days for the 'Espada Vermelha' (SOUZA et al, 2015), being the first flowers open only after 21 days from the beginning of inflorescence development (KAVATI, 2004). Similar results were observed by Lucena et al (2007) in 'Tommy Atkins' cultivar which reported that it takes 25 days to start the flowering. However, the 'Ubá' mango in 2011 required six weeks for the opening of the first flowers and in 2012, only five weeks.…”

There are little information in the scientific literature on flowering and fruiting of 'Ubá' mango trees. These information enables to know the proportion of hermaphrodite flowers in inflorescence, fruit set percentage and developmental stages of the fruit. In this study evaluations on inflorescence and fruit development of the 'Ubá' mango tree (Mangifera indica L.) were carried out, as well as the determination of the required number of heat units for full fruit development. Thirty branches whose terminal buds were swollen were selected from five mango trees. With the aid of a camera and a caliper, the panicle and fruit development were evaluated weekly until full fruit development. A digital thermometer was used to record ambient temperatures during fruit development in order to estimate the number of heat units required for complete development of the fruits. Male and hermaphrodite flowers of the panicles were also identified and counted. The developmental cycle of 'Ubá' mango from the beginning of apical bud swelling to commercial harvest of the fruit lasted 168 days in 2011 and 154 days in 2012. The number of hermaphrodite flowers and the percentage of fruit set in the inflorescence in 2011 were 32.3 and 0.066%, respectively; and 122.1 and 0.099% in 2012, respectively. There was accumulation of 3,173 heat units from flower bud swelling to full development of the 'Ubá' mangoes.

“…Total soluble solids and pH increase, whereas tritatable acidity decreases (Table 1). Generally, soluble solid content in mango range from 7.0 to 17.4°Brix, depending on the variety, the production place, and maturity stage (Lucena et al 2007). For BOsteen^variety, the mature stage where the fruit attains the stage of maximum consumer acceptability is reached when the mangoes have around 14-15°B rix (Vilela et al 2013).…”

The objective of the study was to evaluate the use of a robot gripper in the assessment of mango (cv. BOsteen^) firmness as well as to establish relationships between the nondestructive robot gripper measurements with embedded accelerometers in the fingers and the ripeness of mango fruit. Intact mango fruit was handled and manipulated by the robot gripper, and the major physicochemical properties related with their ripening index were analyzed. Partial least square regression models (PLS) were developed to explain these properties according to the variables extracted from the accelerometer signals. Correlation coefficients of 0.925, 0.892, 0.893, and 0.937 with a root-mean-square error of prediction of 2.524 N/ mm, 1.579°Brix, 3.187, and 0.517, were obtained for the prediction of fruit mechanical firmness, total soluble solids, flesh luminosity, and ripening index, respectively. This research showed that it is possible to assess mango firmness and ripeness during handling with a robot gripper.

“…Na safra 2015/2016, o ciclo reprodutivo da mangueira teve menor duração, 91 dias; este resultado foi inferior aos encontrados por Morais et al (2002), 96 dias, Lucena et al (2007), 98 dias, ambos na região nordeste do Brasil, e Rodrigues et al (2013), 110 dias, na mesma área de estudo, estes determinaram os dias necessários para a manga variedade Tommy Atkins atingir a maturação fisiológica desde o florescimento até a maturação.…”
