“…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 '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 evaluated fruits showed morphological characteristics similar to those presented by cv. Ubá, averaging 70 mm for longitudinal diameter and 55 mm for transverse diameter (RUFINI et al, 2011). The average fresh weight of 124.9 g (Table 1) characterizes 'Imbú' as a cultivar of small fruits, what discourages its acceptance in in natura market.…”

-Although mango is one of the tropical fruits of greater interest in world trade, literature concerning their rootstocks (characteristics and utilization) is scarce. This study aimed to characterize mango plants from cv. Imbú, widely used as rootstock in the Zona da Mata region, Minas Gerais (MG), Brazil. Though fruits of this cultivar do not present desirable commercial characteristics, this study allowed us to characterize part of plant morphology and fill a gap in the literature, providing subsidies for future investigations. For such, 'Imbú' plants (≈ 4-years old) from the collection of the Universidade Federal de Viçosa, located in Viçosa -MG were evaluated. The descriptors were: (i) leaf blade division;(ii) leaf composition; (iii) petiole length in relation to leaf blade; (iv) phyllotaxis, (v) leaf position in relation to the branch insertion; (vi) leaf shape; (vii) leaf apex and base angles; (viii) leaf margin category; (ix) venation; (x) leaf length and thickness; (xi) leaf length/thickness ratio; (xii) leaf texture; (xiii) leaf fragrance; (xix) leaf color. The leaves were depicted as lanceolate, with entire margins and sharp angles at the base and apex of the leaf blade. The intensity of the green color of the leaf blade was considered intermediate and the abaxial surface staining showed less intense than that observed in the upper side. The fruits were processed and separated into peel, pulp and seeds in order to evaluate the flesh color, fresh weight and percentage of seeds, peel and pulp. Was determined the soluble solids content, starch concentration, the peel and the pulp color, the cerosity, the percentage evaluation of peel, pulp and seed and the pulp firmness. The average number of germinated seedlings per seed was estimated for 230 sown seeds.

IMBÚ RESUMO -Apesar de a manga ser uma das frutas tropicais de maior interesse no comércio mundial, a literatura sobre os seus porta-enxertos (características e utilização) é escassa. Este estudo teve como objetivo caracterizar as mangueiras da cv. Imbu, amplamente utilizada como porta-enxerto na região da Zona da Mata de Minas Gerais (MG), Brasil. E, embora frutos dessa cultivar não apresentem características comerciais desejáveis, este estudo permitiu caracterizar parte da morfologia da planta e preencher uma lacuna na literatura, fornecendo subsídios para futuras investigações. Para tal, folhas completamente expandidas da porção mediana de ramos expostos à luz solar e frutos plenamente desenvolvidos foram coletados de plantas da cv. 'Imbu' (≈ 4 anos de idade) da coleção da Universidade Federal de Viçosa, localizada no município de Viçosa -MG. Os descritores foram: (i) divisão lâmina de folha; (ii) a composição da folha; (iii) comprimento do pecíolo em relação à lâmina de folha; (iv) filotaxia, (v) a posição das folhas em relação à inserção do ramo; (vi) a forma de folha; (vii) ângulos do vértice da folha e de base; (viii...
