Besides honey and propolis, bee products already well consolidated, pollen also has relevant economic, nutritional and functional value. As the quality of the final product is directly related to the region where it is collected and processed, this work has evaluated the nutritional and microbiological quality of two dehydrated bee pollens from São Paulo state and the other produced by beekeepers from northern of Mato Grosso state, but with no inspection. Physical-chemical and microbiological quality, phenolic composition and mineral profile analysis were performed. It was observed that both pollens presented satisfactory quality regarding protein contents (24.8 ± 2.4 g 100 g-1), total sugars (36.2 ± 1.1 g 100 g-1), lipids (4.0 ± 0.3 g 100 g-1), ashes (2.6 ± 0.05 g 100 g-1), free acidity (238.7 ± 4.5 mEq Kg-1) and pH (4.8 ± 0.03), however regarding the humidity levels (6.6 ± 2.2 g 100 g-1) both samples were not in accordance with recommended by law (4 g 100 g-1). The bioactive profile has shown a significant amount of phenolic compounds (37.3 ± 1.1 mg GAE g-1) and flavonoids (41.8 ± 2.5 mg QE g-1), besides potential antioxidants around, approximately, 50 and 80%. Microbiological analyzes have revealed low bacterial contamination (≤ 3.6 MPN g-1), molds and yeasts (variation between 1.2x103 and 4x101 CFU g-1), according to values stipulated by the current legislation, being observed the absence of Salmonella sp. and Escherichia coli. The bee pollens investigated have nutritional quality and safety for consumption. However, pollen from São Paulo state showed greater antioxidant potential, probably due to its higher content of phenolics when compared with pollen from Mato Grosso state.

Niagara Rosada

Abtract In Brazil, the producers have changed used rootstocks to get more vigor to scion. Rootstocks change the distribution of bud fruitfulness over grapevine shoots and the expression of the bud fruitfulness into fruit yield. Hence, these modification could alter ideal pruning length. In this way, it was evaluated bud fruitfulness, fruit yield and quality of ‘Niagara Rosada’ grapevine grafted onto rootstocks: ‘IAC 766’, ‘IAC 572’, ‘IAC 313’, ‘IAC 571-6’, and ‘Riparia do Traviu’, which ‘IAC 766’ is the most used rootstock in São Paulo State, nowadays. The evaluations were performed over three crop seasons, in a vineyard located in Louveira, SP. Two evaluations were performed in Brazilian traditional season, and one crop pruning was performed in Brazilian summer, called “off-season”. In traditional seasons, the bud fruitfulness was evaluated from the first to fourth bud in 2014 and to the fifth in 2015. In the off-season, bud fruitfulness was evaluated from the fifth to eighth bud. Fruit yield and quality were also evaluated over the three production cycles. Bud fruitfulness of ‘Niagara Rosada’ grafted onto the evaluated rootstocks showed that this characteristic was more affected by the environmental conditions, confirmed due to alteration of bud fruitfulness through production cycles. Additionally, no effect of rootstock was observed on fruit yield, and quality of ‘Niagara Rosada’. Only isolated variations were detected, and these are not enough to confirm the influence of rootstocks on scion of ‘Niagara Rosada’. Although no effect of rootstocks on bud fruitfulness, fruit yield and quality has been observed in the evaluated conditions, all rootstocks are recommended to be used in combination with ‘Niagara Rosada’.

Esterase Phenotypes

Teak (Tectona grandis Linn. F.) is one of the most important forest crops in Brazil, occupying areas in different regions, such as Goiás, Mato Grosso, Paraná, and São Paulo states. Teak wood is used for many purposes such as shipbuilding, rolling and plywood, firewood, and charcoal. In May 2011, teak symptomatic feeder root samples, exhibiting inconspicuous, small galls, were collected in the municipality of Piracicaba, São Paulo State, Brazil (22°41′46.90″S, 47°38′36.84″W). Specimens were identified through perineal patterns and esterase phenotypes of 20 adult females (1,2). Perineal patterns and esterase phenotypes were consistent with those described for Meloidogyne arenaria (Neal, 1889) Chitwood, 1949 and M. javanica (Treub, 1885) Chitwood, 1949. Perineal patterns of M. arenaria showed a low dorsal arch, compressed dorsolaterally, with lateral field marked by some forked and broken striae; no punctate markings between anus and tail terminus were observed. Perineal patterns of M. javanica were rounded, with low dorsal arch, striae smooth, lateral field distinct, clearly demarcated from striae by parallel lines. From the esterase electrophoresis we obtained A2 (Rm:1.2;1.3) and J3 (Rm:1.0;1.25;1.4) phenotypes, typical from M. arenaria and M. javanica, respectively. To our knowledge, this is the first report of M. arenaria parasitizing teak roots in Brazil and elsewhere (new host) and the first report of M. javanica infecting teak in the State of São Paulo. Previously, M. javanica was reported to be infecting teak-growing areas in the State of Mato Grosso (3). This finding has a great importance, not only by the inclusion of these parasites in teak pathological scenario, but also for predicting possible damage in plant species used in teak-based intercropping systems.

We analyzed the spatial relation between incomplete vaccine coverage for children and the distance from vaccination services. This was a cross-sectional study of children from 13 to 35 months of age from the cities of São Luís (Maranhão State) and Ribeirão Preto (São Paulo State), Brazil, and from basic health units (UBS, in Portuguese). The sample consisted of 2,744 children from São Luís and 3,325 from Ribeirão Preto. Data about incomplete vaccine coverage for children were obtained from the BRISA birth cohorts. Data about the quality of UBS vaccination services were obtained from the first cycle of the Brazilian National Program for Improvement of Access and Quality of Basic Care (PMAQ-AB, in Portuguese). For the spatial analysis, we determined the distance between the residence of the children (with and without a complete vaccine calendar) and the vaccination services of the UBS (classified according to number of structural items). Incomplete vaccine coverage was more pronounced in São Luís, with greater percentages for human rotavirus and triple viral vaccines, with the latter being the least available. In Ribeirão Preto, incomplete BCG vaccine coverage was more pronounced, with the tetravalent vaccine being the least available. Children from the two cities showed similarities: most of them had adult mothers with 9 to 11 years of schooling and did not reside with siblings in the household. They also showed differences: in São Luís, most mothers belonged to the economic class C, while in Ribeirão Preto they belong to the A and B classes. In the two cities with different socioeconomic conditions, complete vaccine coverage seemed not to depend on the location or quality of the vaccination service. Although São Luís showed a better structure of the services, incomplete vaccine coverage was higher compared to Ribeirão Preto.

A contribuição do município de Guarulhos (Estado de São Paulo) para a qualidade de água do Sistema Alto Tietê. Guarulhos (SP) tem apresentado índices de crescimento populacional acima da média da Região Metropolitana de São Paulo (RMSP). A Bacia Hidrográfica do Rio Baquirivu Guaçu (BHRBG), onde se localiza o Rio Baquirivu Guaçu, é o vetor de expansão urbana do município e da região. Este trabalho apresenta uma análise da qualidade das águas do Rio Baquirivu-Guaçu na entrada e na saída do município de Guarulhos, avaliando os efeitos da implantação das ETEs e do uso da terra sobre a qualidade das águas do Rio Baquirivu-Guaçu, entre os anos de 2010 e 2014. Para isto foram elaborados os mapas de uso de terra no período analisado, uma análise do funcionamento das ETEs na área de estudo, e a análise estatística dos Índices de Qualidade de Águas (IQA) e de seus parâmetros nos diferentes pontos do rio. Os dados referentes às análises físico-química e microbiológica do Rio Baquirivu-Guaçu indicam uma qualidade de água na saída do município de Guarulhos (IQA=16), muito inferior àquela que recebe do município de Arujá (IQA=32). Os valores médios, em especial para os parâmetros DBO, OD, TU, ST e CF indicam uma piora na qualidade das águas do Rio Baquirivu-Guaçu no ponto BQGU03850. Os valores dos parâmetros NT, PT e pH foram muito próximos para ambos os pontos da entrada e saída da bacia. A análise entre a evolução do uso da terra e a qualidade da água demonstra as consequências do processo inadequado de crescimento urbano na bacia e que as fontes poluidoras domésticas e industriais representam considerável risco à qualidade das águas, demonstrando que as obras de saneamento realizadas até o momento não foram eficazes na redução de cargas poluidoras das águas do rio Baquirivu-Guaçu.

Water Yam

This study aimed to fingerprint 36 water yam (Dioscorea alata) accessions using microsatellite markers. Ten accessions were collected in local markets from several municipalities in Brazil, eight were obtained from the 'Instituto Agronômico de Campinas' (IAC) germplasm collection and eighteen were collected directly from growers from São Paulo state. A total of nine microsatellite loci were used in the analysis. Loci revealed high polymorphism verified by elevated PIC values (0.57-0.77), and by high gene diversity and Shannon-Wiener indices (0.69 and 1.29 on average, respectively). The accessions were classified into two groups based on clustering analysis. One group contained mostly accessions from the IAC collection, including a commercial cultivar acquired in a market in the city of Cuiabá, Mato Grosso state. The second group was composed of most accessions, including those collected directly from growers and markets in São Paulo, a few accessions from the IAC collection, and an accession from Puerto Rico, named 'Florida', which is the most cultivated in Brazil. Several duplicates were identified in this study, including accessions obtained from two farmers in Mogi Guaçu and Mogi Mirim, São Paulo state. However, some of these accessions were allocated in different sub-groups, within this second group. Results suggested the hypothesis of different origins for accessions currently cultivated in Brazil. Similar accessions obtained from different municipalities revealed the commercialization of the same accessions at different locations.
