“…The relationship between the degree of maturation and the postharvest fruit quality has been widely described and it is often reported that reduction in firmness leads to increased susceptibility to mechanical damage, decays, physiological alterations and, consequently, a shorter shelf-life (MARI et al 2003;FISCHER et al, 2008). Regarding the firmness of mango fruits, Lederman et al (1998) suggested that the ideal value should exceeds 90 N for a consistent postharvest longevity and a higher resistance to transportation.…”

“…The soluble solids content was determined with the aid of a portable refractometer Atago N1, with scale ranging from 0 to 53ºBrix. Starch concentration was determined from the remaining residue from ethanol extractions using the methodology described by McCready et al (1950) and modified by Patel (1970). The peel color was evaluated by making two readings on opposite sides of the equatorial region of the fruit.…”

-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...

Período de estratificação e desenvolvimento inicial de Seedlings de pessegueiro em função do número de sementes por endocarpo

et al. 2008

RESUMOOs frutos de pêssego podem apresentar, no interior do endocarpo, uma ou duas sementes. Porém, não se sabe se o número de sementes por endocarpo pode apresentar diferenças no comportamento durante sua estratificação e posterior desenvolvimento da planta, para uso como porta-enxerto. Conduziu-se este trabalho para avaliar o efeito do número de sementes por endocarpo sobre o período de estratificação e desenvolvimento inicial de seedlings de pessegueiro, cultivar Campinas-1 e progênie 290. Os trabalhos foram realizados no Departamento de Fitotecnia, da UFV, durante o período de fevereiro a agosto de 2005. Foram realizados dois experimentos, sendo o primeiro de germinação e o segundo relacionado ao desenvolvimento inicial de mudas. No primeiro experimento, as sementes foram estratificadas em câmara fria, à temperatura de 5°C, avaliando-se a germinação das sementes e estimando-se a data correspondente à 80% de germinação. Após a germinação, iniciou-se o segundo experimento, no qual procedeu-se à semeadura das sementes em recipiente plástico (32 cm x 16 cm), contendo a mistura de Latossolo Vermelho + Plantmax 3:1 v/v, enriquecido com P 2 O 5 (3,0 kg m -3 ), no interior da casa de vegetação. Concluiu-se que o número de sementes por endocarpo teve relação com o período de estratificação, sendo o menor período para obtenção de 80% de germinação obtido com as sementes, que eram originárias dos endocarpos. O desenvolvimento inicial do pessegueiro não foi influenciado pelo número de sementes, por endocarpo. Termos para indexação: Pêssego, Prunus persica, germinação, mudas. ABSTRACTThe peach fruit can have into the endocarp one or two seeds. However, it is unknown if the number of seeds per endocarp can have different behavior during its stratification and subsequent plant growing for using as rootstocks. The aim of this work was to evaluate the effect of seed number per endocarp on the peach seedling stratification and initial growing of variety Campinas-1 and progeny 290. The work was carried out at the Department of Plant Science, of the Federal University of Viçosa (MG), Brazil, from February to August, 2005. It was performed two experiments, being the first one based on germination of seed and the second one based on initial growing. In the first experiment, the seeds were stratified in cold chamber (5°C), where the percentage of germination was evaluated, estimating the date corresponding to 80% of germination. After the germination, at greenhouse, the second experiment was initiated, in which the sowing of the seeds occurred in plastics recipients (32 cm x 16 cm), containing Red Latosoil + Plantmax mixture (3:1 v/v, enriched with P 2 O 5 -3,0 kg m -3 ). It was concluded that the number of seeds per endocarp had relationship to the stratification period, being the shortest period to obtain 80% of germination observed in seeds from endocarp that possessed just one seed. The peach seedling initial development was not influenced by the seed number per endocarp.

Common bean (Phaseolus vulgaris L.) is an important food legume. However, drought influences its entire growth and development process and can cause yield losses. The influence of drought stress is the most severe in the bud stage. The major objective of our study was to identify a series of loci involved in drought stress response in the bud stage using association analysis. In this study, 361 common bean germplasms were used to investigate germination vigour (GV) and germination rate (GR) under distilled water and drought stress conditions.The common beans showed large variations in GV and GR, with GV ranging from 6.67% to 100% and 0 to 73.33% and GR ranging from 66.67% to 100% and 0 to 100% in distilled water and under drought stress, respectively. A genome-wide association study (GWAS) of 361 accessions was conducted using 3724159 single nucleotide polymorphisms (SNPs) and revealed 2 and 11 candidate SNPs associated with relative germination rate (RGR) and relative germination vigour (RGV), respectively. Three loci were collocated with loci previously reported as being related to drought tolerance. A total of 180 candidate genes were identified, many of which were related to ion transport and oxidation-reduction reactions. A major haplotype for RGV was identified on chromosome 6. These results provide new insight into the This article is protected by copyright.
