Chilling and forcing requirement of five international fig cultivars grown in Southeastern Brazil

Figshare (2022)

Laís Naiara Honorato Monteiro Sarita Leonel Jackson Mirellys Azevêdo Souza Rafael Bibiano Ferreira Marcelo de Souza Silva

ABSTRACT Chill hours availability influence break dormancy, sprouting and production of temperate fruits trees in different regions. However, there are few reports on the subject for fig tree. This study aimed to evaluate the effects of the accumulated chilling hours on the physiology and dormancy release of fig cultivars. Stem cuttings of five fig cultivars were collected at the end of winter over two crop cycles and exposed to 0, 40, 80, 120 and 160 accumulated chilling hours (CH) in a cold chamber (8±0.5 ºC). Physiology of fig buds was then evaluated with regards to antioxidant enzymes activity, carbohydrate and nitrogen contents. The exposure of fig stem cuttings with two buds to different accumulated CH presented physiological changes for antioxidant enzymes activity, carbohydrates and nitrogen contents and confirming that the cultivars responded differently to the climatic conditions of each crop cycle. Results detected that the lowest accumulated CH in field in 2018 (2.7 CH) enabled a greater effect of the artificial CH when compared to 2017 (19.5 CH). Each fig cultivar had a critical accumulation point. The cultivars Roxo de Valinhos and Pingo de Mel require less CH to break dormancy, while Troyano requires more CH to finish this vegetative rest period.

Selección de microorganismos para la producción de vinos higiénicos: I. Producción de sulfuro de hidrógeno e histamina durante la fermentación vínica

Alimentaria: Revista de tecnología e higiene de los alimentos (1987)

Francisco Bravo Abad Émerson Loli Garcia

espanolSe estudio el comportamiento de la especie eurioica Saccha. ellipsoideus frente a la adicion de sustancias con azufre, utilizadas en Enotecnia y a los factores fisicoquimicos que pueden influir en la produccion de histamina y sulfuro de hidrogeno durante la fermentacion. Tambien se estudiaron otras especies de levaduras, aisladas de las diferentes fases fermentativas del mosto de uva, y combinaciones binarias y ternarias de algunas de ellas. Los niveles de sulfuro de hidrogeno e histamina acumulados por combinaciones binarias y ternarias de levaduras son iguales a los minimos producidos, en cultivos puros, por las especies que integran la asociacion, de modo que, tambien desde este punto de vista, las asociaciones secuenciales de levaduras son beneficiosas para la produccion de vinos higienicos. EnglishSaccharomyces ellipsoideus, activity is studied, as a model of high fermentative power vine yeasts in contrast with the effects of sulphur substances used in Enotechnology and with physic-chemical factors that can influence the production of hydrogen sulphide and histamine during must fermentation. Some characteristic yeast species, from different fermentative phases, are also studied, as well as some binary and ternary combinations among them. The histamine and hydrogen sulphide levels accumulated vy the metabolisme of these yeast combinations are equivalent to lower rates produce by pure cultures of the single yeasts that integrate these associations. That way these yeast associations are likely to be highly beneficious in hygienic wines making.

Potato cultivars as a source of starch in Brazil: physicochemical characteristics of the starches and their correlations

Australian Journal of Crop Science (2019)

Émerson Loli Garcia Ezequiel Lopes do Carmo Joaquin Gonçalves de Pádua Célia Maria Landi Franco Magali Leonel

As a source of starch, potato remains unexploited in Brazilian industries, where they typically utilize corn and cassava. Considering the emerging need for using potato as a source of commercial starch, this study evaluated starches extracted from seven cultivars of potatoes with limited commercial usage in Brazil. Potatoes were grown under the same environmental conditions and cultural practices. After harvesting, the potato tubers were processed for the extraction of starch. The proximate composition, amylose content, resistant starch, minerals, as well as pasting and thermal properties of extracted starch samples were analyzed. Starch characteristics varied with the cultivar. Using correlation analysis, we demonstrated that minerals have a robust effect on starch characteristics. Moreover, positive correlations were observed between phosphorus, potassium, magnesium, resistant starch, viscosity peak, breakdown, and gelatinization enthalpy. Calcium had a positive correlation with the amylose content and the percentage of starch retrogradation. Starch samples showed important differences in their physicochemical properties, which are advantageous for industrial applications allowing a larger diversification and incentive to the production of potato for industry in Brazil.

José Ítalo Bacchi, s/n - Jardim Aeroporto, CEP 18606-851, Botucatu, SP, Brasil. marcelo.denadai@fatec.sp.gov.br RESUMO: A silagem é uma importante tecnologia utilizada pelos produtores rurais e indispensável dentro dos sistemas de produção intensivos ou não. A silagem resulta da ação de microrganismos que fermentam o material orgânico, resultando em um alimento rico e nutritivo para o gado leiteiro. Entretanto, estudos demonstrando a viabilidade do processo em pequenas propriedades são escassos. Neste sentido o trabalho objetivou avaliar a viabilidade da cultura de milho utilizada para a produção de silagem em uma propriedade leiteira familiar, bem como, identificar método para maximizar o retorno financeiro à propriedade. Os resultados demonstraram que um melhor planejamento na aquisição dos insumos e a utilização de plantio de cobertura, podem reduzir os custos e a quantidade dos insumos utilizados. Frente ao custo gerado pela produção do milho ensilado, se o produtor vender o grão quando o valor da saca for superior a R$ 75,50 e, comprar o alimento de terceiros, seu lucro líquido será maximizado em 5%. Palavras-chave: leite, custo de produção, planejamento ECONOMIC FEASIBILITY OF THE CORN CROP TO SILAGE IN A DAIRY CATTLE PROPERTY ABSTRACT: Silage is an important technology used by rural producers and indispensable in production systems intensive or not. The silage results from the action microorganisms that fermented organic matter, resulting in a rich and nutritious food for dairy cattle. However, studies demonstrating the viability of this process on small properties are scarce. In this sense, this work aimed to evaluate the viability of corn crops used for the production of silage on a family dairy farm, as well to identify a method to maximize financial return to the property. The results showed that good planning in the acquisition of inputs and use of cover crops can reduce the costs and quantity of inputs used. In view of the cost generated by the production of corn silage, if the producer sells the production when the value of the bag exceeds R$ 75.50 and buy the silage from third parties, his net profit will be maximized by 5%.

Improving the nutritional value and extending shelf life of red guava by adding calcium chloride

LWT (2020)

Luiza Rocha Ribeiro Sarita Leonel Jackson Mirellys Azevêdo Souza Émerson Loli Garcia Magali Leonel

The high nutritional value of guavas is much appreciated and valued by consumers but extending the shelf life of these fruits is one of the most crucial factors to increase their commercialization. The present study aimed to evaluate the effects of the pre-harvest application of calcium chloride (0, 0.5, 1.0, 1.5, and 2%) on guava fruits and to evaluate the quality characteristics of the fruits during storage (0, 2, 4, and 6 days). The results showed that the pre-harvest sprays of 1.0% CaCl2 led to an increase in the levels of calcium in the fruits (0.82 g kg−1). The application of 1.0% CaCl2 also promoted 40% increase in ascorbic acid content after harvest (196.5 mg 100 g−1). The lowest weight loss and rot incidence occurred at 1.0% CaCl2. In addition, there was a decrease in the action of pectinmethylesterase and polygalacturonase in storage. Thus, the pre-harvest application of 1.0% CaCl2 in the red guava can preserve the quality of the fruit and increase the nutritional value.

Tekhne e Logos (2020)

Émerson Loli Garcia Carlos Eduardo Ciccone

As plantas alimenticias nao convencionais (PANCs) sao plantas que crescem espontaneamente sem a necessidade de manejo, sendo que majoritariamente sao tratadas como plantas daninhas. As PANCs apresentam potencial nutricional e medicinal pouco explorados atualmente, sao fontes de vitaminas A, C e as do complexo B, alem de minerais como ferro, calcio e potassio e os bioativos como antioxidantes por exemplo. Neste estudo objetivou-se avaliar qualitativamente as PANCs nativas da cidade de Botucatu/SP e o nivel de informacao da populacao a respeito dos beneficios que podem proporcionar a saude. Os resultados demonstraram que a populacao botucatuense nao apresenta nivel de informacao satisfatorio quanto as PANCs que justificasse seu consumo diario, em muitos casos acreditam-se serem toxicas. Apos a participacao no estudo, em torno de 33% dos participantes afirmaram que passarao a consumir este tipo de alimento e 48% certamente consumira uma das PANCs aqui avaliadas. Palavras-chave : Alimentacao Saudavel. Consumo. Fins Medicinais. Nutricao. QUALITATIVE ANALYSIS AND RESEARCH OF NATIVE PANCs IN BOTUCATU/SP Non-convectional food plants (NCFP) are plants that grow freely without the need for management and are treated as weeds. NCFPs show little explored nutritional and medicinal potential even being sources of vitamin A, C and those of B complex, in addition to minerals such as iron, calcium and potassium and the bioative compounds as antioxidants. This paper aims to analyse qualitatively native NCFPs in Botucatu, Sao Paulo state as well as information level of population regarding the benefits that such plants can have on health. Results showed the town´s population have low level of information regarding NCFPs to the support their daily consumption, and in many cases people believe such plants to be toxic for health. However after participating in this research, around 33% the people said they will consume this type of food and 48% will probably consume one of the NCFPs studied. Key words: Healtly eating.

PRODUTIVIDADE E QUALIDADE DE RAÍZES DA MANDIOQUINHA-SALSA EM DIFERENTES NÍVEIS DE ADUBAÇÃO NPK

Colloquium Agrariae (2018)

Adalton Mazetti Fernandes Émerson Loli Garcia Magali Leonel Lydia Helena da Silva de Oliveira Mota

The storage roots of arracacha have high nutritional value, being rich in carbohydrates, minerals, vitamins A and C, and starch of high digestibility. However, in this crop one of the decisive factors for the production of roots with higher nutritional value is the balanced fertilization. The aim of this study was to evaluate the yield and nutritional quality of storage roots of arracacha, grown at increasing levels of NPK fertilization. The experiment was conducted in the randomized blocks design, with eight replications. The treatments consisted of three NPK levels (AD0 = unfertilized cultivation, AD1 = cultivation with 50% of recommended fertilization, and AD2 = cultivation with 100% ofrecommended fertilization). It was observedthat higher levels of NPK fertilization increase the number, size and marketable yield of storage roots of arracachacrop. NPK fertilization also increases the size and contentsof K, Mg, and Mn of storage roots, without interfering with the pulp pH and contentsof protein, Ca, Cu, and Fe. However, when the increase in root size is not accompanied by an increase in dry matter content, the starch, P, and Zn contents of the roots reduce with increasing levels of NPK fertilization.

Yield and nutritional requirements of cassava in response to potassium fertilizer in the second cycle

Journal of Plant Nutrition (2017)

Adalton Mazetti Fernandes Bruno Gazola Jesion Geibel da Silva Nunes Émerson Loli Garcia Magali Leonel

Potassium (K) is one of the most absorbed nutrients by cassava because it acts on the synthesis and starch accumulation in the storage roots. Here, we show that K application at the beginning of the second vegetative cycle of cassava submitted to shoot pruning increased the yield of roots and starch, and the nutrient demand of plants. Application of 45–89 kg ha−1 dipotassium oxide (K2O) in the second cycle increased the yield of storage roots and starch from 36–49% and K applied at this time had a greater effect on the synthesis and allocation of starch in the storage roots. K supply increased the accumulation of N and S by 2.0- to 3.0-fold and the accumulation of other nutrients by 1.4- to 1.7-fold. The removal of phosphorus (P), manganese (Mn), and zinc (Zn) by storage roots was not affected by K application, whereas the removal of other nutrients increased by 1.3- to 4.3-fold.
