“…Hence, both the biochemical process and CO 2 fixation are damaged by increased leaf temperature. Oliveira et al (2013), evaluating soluble sugar contents over the fruit development period, found the mean value of 37 mg g -1 of dry matter in leaves, a higher result than the one found in our study. Evaluating physiological traits, in terms of doses applied via irrigation, it is possible to see that the doses did not have a significant interaction with samplings.…”

“…Paclobutrazol increased the percentage of flowering in plants and, consequently, the consumption of carbohydrates for the formation and development of panicles, resulting in lower carbohydrate contents in leaves. Oliveira et al (2013), evaluating the total soluble sugar contents in leaves over the tumescence period of floral gems, obtained a different behavior from the one found here: a quadratic reduction, in terms of different paclobutrazol doses. The lowest soluble sugar content was 33 mg g -1 of dry matter in leaves of 'Ubá' mango tree, which corresponds to the dose of 1.76 g of paclobutrazol per linear meter of canopy.…”

Paclobutrazol application in mango tree floral induction is followed by changes in the hormonal balance and carbohydrates production. This study aimed at evaluating the physiological and biochemical variables of mango tree (Palmer cultivar) by applying paclobutrazol doses via irrigation. The experimental design was randomized blocks, with five paclobutrazol doses (0.7 g, 1.0 g, 1.3 g, 1.6 g and 1.9 g of a.i. per linear meter of canopy) and one additional treatment, with one dose in the conventional form of application (1.9 g of a.i. per linear meter of canopy), and four replicates. The variables analyzed were: photosynthesis rate; stomatal conductance; transpiration; leaf temperature; CO2 ratio; total protein content; reducing, non-reducing and total soluble sugars in leaf tissue and fruit; and nitrate reductase enzyme. The lowest values for photosynthesis rate and stomatal conductance were obtained with paclobutrazol applied via irrigation. The highest values for gas exchange were obtained with the lowest paclobutrazol doses applied via irrigation, showing that this kind of application is efficient and that it is possible to reduce the application dose via irrigation system. The highest carbohydrate contents in the leaf tissue were observed for the doses of 1.06 g and 1.09 g of a.i. per linear meter of canopy, applied via irrigation. The carbohydrate contents in fruits decreased in response to the paclobutrazol dose. The application methods and doses applied via irrigation did not influence the nitrate reductase activity.

“…Similar values were observed by some authors for 'Ubá' mango trees in the "Zona da Mata" region (Oliveira et al 2013, Rufini et al 2010, who found mean values between 18.8 and 65. The ratio has been used to evaluate the fruit flavor, as it increases with maturation (Chitarra & Chitarra 2005).…”

“…The mean pulp yield of fruits was 65 %, being close to values found by Silva et al (2009) and Oliveira et al (2013), from 61 % and 69 %, respectively, for the 'Ubá' cultivar. The use of fruits with high pulp yields is important for industrial processing.…”

The 'Ubá' mango tree cultivar is very important for the juice industry in the "Zona da Mata" region of the Minas Gerais State, in Brazil, but problems such as uneven flowering and low yield have discouraged producers. This study aimed at evaluating the effect of paclobutrazol, combined with branch tip pruning, on the flowering induction and quality of 'Ubá' mango tree fruits. Treatments were distributed in a 5 x 2 + 1 factorial arrangement, consisting of five paclobutrazol doses (0 g, 0.50 g, 1.00 g, 1.50 g and 2.0 g per linear meter of canopy), with and without branch tip pruning, in a randomized blocks design, with four replicates. The flowering percentage, number of panicles per branch, total flowers per panicle, male/hermaphrodite flowers ratio, number of fruits per branch and fruit quality were evaluated. Plants treated with tip pruning showed a higher flowering percentage. There was an increase in the flowering percentage in response to the paclobutrazol dose, reaching a maximum level at the dose of 1.62 g per linear meter of canopy. Plants submitted to branch tip pruning had a higher number of panicles per branch. There was an increase in the male/hermaphrodite flowers ratio with increasing paclobutrazol doses. Branch tip pruning increased the number of fruits per branch. There were no differences in fruit quality in response to the paclobutrazol application. It was concluded that the paclobutrazol application at the dose of 1.62 g per linear meter of canopy, combined with branch tip pruning, increases the flowering of the 'Ubá' mango tree and does not change the fruit quality.

“…The explanation for the differences found in the two studies for this cultivar may lie in ripeness stage at time of harvest. Silva et al (2009) Oliveira et al (2013), the carotenoids found in the fruit of 46 Ubá mangoes varied between 0.61 and 2.12 mg 100g -1 pulp.…”

The aim of this study was to physically and chemically characterize the fruit quality of some mango cultivars grown in a subtropical climate region of São Paulo, in the municipality of São Manuel. The experiment design was totally randomized, consisting of 4 treatments (Palmer, Parwin, Tommy Atkins and Haden cultivars) and 4 repetitions for the physical analyses and 6 repetitions for the chemical analyses. Each repetition composed of 5 fruit from each cultivar. Fruits from two production years: 2011/2012 and 2012/2013 were used for the study. According to the results we concluded that all of the cultivars are suitable for industrialization. Fruit from the Palmer and Parwin cultivars are interesting, in terms of harvesting and transporting as they showed the best values for firmness. The fruits of the Palmer cultivar presented higher physical and chemical quality.
