Phenological cycles, thermal time and growth curves of mango fruit cultivars in subtropical conditions

There are many mango cultivars available in different regions. It is about time we analysed their productive behavior in these areas, as well as their phenological performance. This study aimed to evaluate: phenological cycles, thermal time and growth curves of mango fruit cultivars in subtropical conditions. For this study we used the following cultivars: Espada Vermelha, Keitt and Palmer. All the experiments were done at UNESP experimental farm in Sao Manuel (SP), during the agricultural cycle from 2012 to 2013. It was selected 15 branches in each plant, which provided 150 per cultivar. It was determined the number of days of phenological cycles of flowering to fruit ripening, as well as the total number of days to flowering and harvesting. The thermal time was evaluated to each phenological cycle and expressed in accumulation of degree-days. The measurement of the longitudinal diameters (LD) and transverse diameters (TD) of the fruitwere performed in a 12 day’s intervals, from the tenth day after the flowers anthesis, to evaluate the growth curve. Based on the data, it was found that Keitt cultivar requires more days for the fruit to reach physiological maturity and greater accumulation of degree-days to complete its production cycle. The growth curves of the three varieties of fruits have a simple sigmoidal model in function of the days after anthesis.

Growth and flowering of five mango cultivar under subtropics conditions of Brazil

The evaluation of the new cultivars adaptation and yield potential of Mangifera indica L. provides tools to assist and improve the mango production in different climates conditions. This study aimed to evaluate the phenological and reproductive development of five mango cultivars (Bourbon, Haden, Palmer, Parwin and Tommy Atkins), on climate conditions in dry land and four production cycles (from 08/2007 to 01/2011), at São Manuel, São Paulo state, Brazil. The variables were total plant height, trunk height, stem diameter and the first insertion diameter, fruits physical characteristics, yield and harvest period, flowering seasonality and morphological characterization of the inflorescences. It was found that the four-year-old plants of Haden cv. reach 4.0 m high and 0.20 m of trunk diameter. Bourbon cultivar had the highest flowering period, from April to October. Tommy Atkins cv. had productivities of 14779.07 kg∙ha−1 in the fourth cycle and the productivity of Bourbon, Haden and Palmer cultivars was alternated.

2D-DIGE analysis of mango (Mangifera indica L.) fruit reveals major proteomic changes associated with ripening

A comparative proteomic investigation between the pre-climacteric and climacteric mango fruits (cv. Keitt) was performed to identify protein species with variable abundance during ripening. Proteins were phenol-extracted from fruits, cyanine-dye-labeled, and separated on 2D gels at pH 4-7. Total spot count of about 373 proteins spots was detected in each gel and forty-seven were consistently different between pre-climacteric and climacteric fruits and were subjected to LC-MS/MS analysis. Functional classification revealed that protein species involved in carbon fixation and hormone biosynthesis decreased during ripening, whereas those related to catabolism and the stress-response, including oxidative stress and abiotic and pathogen defense factors, accumulated. In relation to fruit quality, protein species putatively involved in color development and pulp softening were also identified. This study on mango proteomics provides an overview of the biological processes that occur during ripening. (C) 2012 Elsevier B.V. All rights reserved.

An investigation about Brazilian mango and grape exports

Purpose - The objective of this paper is to characterise the transactions between European buyers and Brazilian mango and grape producers. Design/methodology/approach - The method selected for this paper was multiple case studies. The Brazilian mango and grape supply chains' export activities to Europe were investigated. The field research was undertaken in Brazil, Germany, The Netherlands and the UK. In total, 41 face-to-face interviews were carried out. Findings - The supermarkets' literature tends to generalise the strategies of retailers focusing on differentiation and preferred suppliers. However, in empirical research conducted in the UK, Germany and The Netherlands it is possible to conclude that the procurement strategies of supermarkets can vary sharply. The results reveal the presence of different agents who demand different quality standards. The level of intensity depends on consumer behaviour, the features of product commercialised and the characteristics of the production segment in each country. Research limitations/implications - First, in relation to the empirical method there is a limitation because the case study does not allow statistical generalisation. Consequently, it will be interesting to undertake quantitative research in order to quantify the variables presented and their impact on the structure of value chains. Second, the research focuses only on two stages of the supply chain, producers and buyers. Practical implications - The differences between UK and German supermarkets challenge the supermarket literature, which tends to generalise the strategies of retailers focusing on differentiation and preferred suppliers. Originality/value - The study shows that the issue of influence and activities of retail agents along the value chain can be analysed taking several variables into consideration: the products commercialised; the distribution segment; and the consumer market. This result opens the way for analysing different structures of the value chain and the impact of these differences on the entry of producers for developing countries into the global market.

Descripción del subsistema estrictamente coordinado de exportación de mango fresco : Passion Fresh

El mango es una de las frutas tropicales cuya demanda mundial ha mostrado un crecimiento positivo y sostenido en el tiempo. El Perú ha logrado destacar como uno de los principales exportadores de mango fresco en el mundo, en este país la mayoría de empresas exportadoras tiene varios años en el mercado y comercializan el producto en verde enviándolo vía marítima. Ese no es el caso de Passion Fresh, que con pocos años en el mercado, ha logrado convertirse en uno de los principales exportadores de mango fresco, comercializándolo con el grado de madurez exacto para ser consumido. Por ello, el objetivo de este trabajo es identificar las innovaciones organizacionales de Passion Fresh a fin de comprender su creciente inserción en mercado internacional. La metodología utilizada fue la epistemología fenomenológica a través de un estudio de caso; sustentada teóricamente en la nueva economía institucional, utilizando el análisis estructural discreto, se hizo énfasis en el ambiente organizacional, analizando las transacciones de la empresa con cada uno de los actores del subsistema y su respectiva alineación. El subsistema se desarrolla en un ambiente institucional que no tiene una política específica para el mango, pero que se ha visto soportado por políticas para productos agrícolas en general. Respecto al ambiente tecnológico las innovaciones solo llegan a aquellos que están agrupados en asociaciones. Y en el ambiente organizacional coexisten dos subsistemas, uno orientado al mercado local y otro al externo, ambos con gran presencia de intermediarios. Los resultados obtenidos muestran a Passion Fresh como un subsistema estrictamente coordinado, con un activo altamente específico, lo que hace que se diferencie de sus competidores, ya que tiene que comercializar el mango vía aérea para que llegue listo para el consumo. Todo esto lo define como el coordinador del subsistema, disminuyendo así los costos de transacción y convirtiéndose en una referencia del sector.

Um Mango e un Cuchillo en el norte : Joao da Cunha Vargas e Jorge Luís Borges em Délibáb de Vitor Ramil

Este trabalho propoe uma leitura de disco Délibáb músico brasileiro Vitor Ramil. A obra é uma musicalizaçao de alguns poemas de Joao da Cunha Vargas e Jorge Luis Borges, e de alguma forma busca aproximar os dois poetas pela proximidade cultural da regiao sul do Brasil com os países da regiao do pampa. Délibáb se refere a ilusao de ótica que faz lugares distantes parecem mais próximos. E precisamente nesta relaçao entre proximidade e distância, realidade e ilusao, identidade e alteridade que este trabalho pretende se debruçar para armar uma leitura sobre a proposta de Vitor Ramil

La necesidad de considerar los riesgos climáticos en la introducción de cultivos tropicales en latitudes medias. El mango en el valle del Guadalhorce (Málaga)

El presente trabajo pretende demostrar que no es recomendable la introducción de un cultivo tropical como el mango (Mangifera indica) dentro del área mediterránea del valle del Guadalhorce (Málaga, España). Es un cultivo en expansión por su rentabilidad económica, pero es necesario atender a los posibles riesgos climáticos para su explotación (tras la gran inversión que requiere). Para justificar esta afirmación se presenta un estudio agroclimático realizado en las parcelas experimentales de la finca de IFAPA (Instituto de Investigación y Formación Agraria y Pesquera de Andalucía) de Churriana (Málaga). Los resultados se obtienen a través de los datos de una estación meteorológica y una modelización territorial a partir de herramientas de análisis espacial con SIG. Se tienen en cuenta las variables térmicas y los vientos como condicionantes principales de la aparición de la necrosis apical: patología mortal para el mango.
