1. Productivity, physicochemical quality and early flowering resistance of experimental onion hybrids
RESUMO A cebola para produzir bulbos ou sementes depende da interação do genótipo com o ambiente. Assim, programas de melhoramento genético devem realizar a seleção com base nas condições climáticas de cada região produtora. Neste estudo, objetivou-se avaliar 17 híbridos experimentais de cebola e dois genótipos comercias (‘Bella Dura’ e ‘Bu

2. Yield and quality of densely cultivated onion cultivars as function of nitrogen fertilization
RESUMO O nitrogênio exerce influência marcante no rendimento e qualidade da cebola. O presente trabalho foi desenvolvido no período de junho a outubro de 2016, tendo como objetivo avaliar a produtividade e qualidade de duas cultivares de cebola sob sistema adensado em função de doses de nitrogênio em Mossoró, RN. Empregou-se o delineamento em blocos c

3. MULTIVARIATE ANALYSIS OF CHEMICAL AND PHYSICAL ATTRIBUTES OF QUARTZIPSAMMENTS UNDER DIFFERENT AGRICULTURAL USES
ABSTRACT The inadequate agricultural management in the semiarid region of northeastern Brazil, associated with the fragility of most soils, has caused degradation of the quality of this resource. This study aimed to evaluate the quality of Quartzipsamments under different uses through the multivariate analysis of chemical and physical attributes. Five areas

4. Visual quality and waste of fresh vegetables and herbs in a typical retail market in Brazil
RESUMO Devido à sua alta perecibilidade, hortaliças folhosas e ervas frescas são transportadas para o mercado logo após a colheita. É de esperar que parte dos danos sofridos durante a colheita e o transporte desses produtos resultem em perda somente nos elos seguintes da cadeia, quais sejam, varejo e consumo. O manuseio inadequado e o uso de estratégia

5. Essential oils in the control of Colletotrichum gloeosporioides f. Sp. cepae in onion seeds
RESUMO A antracnose causada pelo fungo Colletotrichum gloeosporioides f. sp. cepae é umas das principais doenças na cultura da cebola. A principal estratégia de controle deste fungo é o controle químico com fungicida sendo esta técnica utilizada na maior parte dos cultivos. Atualmente vem sendo estudados métodos de controle de doenças que sejam menos

6. Nitrogen Transfer from Cover Crop Residues to Onion Grown under Minimum Tillage in Southern Brazil
ABSTRACT Nitrogen derived from cover crop residues may contribute to the nutrition of onion grown under minimum tillage (MT) and cultivated in rotation. The aim of this study was to evaluate the N transferred from different cover crop residues to the onion crop cultivated under MT in southern Brazil. In June 2014, oilseed radish, black oat, and oilseed radis

7. Chemical Properties in Macroaggregates of a Humic Dystrudept Cultivated with Onion under No-Till and Conventional Tillage Systems
ABSTRACT Nutrients present in soil aggregates are essential for maintaining the productive capacity of agroecosystems and environmental quality. The aim of this study was to evaluate the chemical properties of macroaggregates of a Humic Dystrudept cultivated with onions under a no-till vegetable system (NTVS) compared to the conventional tillage system (CTS)

8. Release of Phosphorus Forms from Cover Crop Residues in Agroecological No-Till Onion Production
ABSTRACT Cover crops grown alone or in association can take up different amounts of phosphorus (P) from the soil and accumulate it in different P-forms in plant tissue. Cover crop residues with a higher content of readily decomposed forms may release P more quickly for the next onion crop. The aim of this study was to evaluate the release of P forms from res

9. Semen quality characteristics of Koekoek breeder cocks influenced by supplemental inclusion levels of onion and garlic mixture at 35-41 weeks of age
ABSTRACT An experiment was conducted to determine the effect of varying dietary supplemental inclusion levels of onion and garlic mixture on semen quality characteristics of Koekoek breeder cocks aged 35-41 weeks. The experimental diets were isocaloric and isonitrogenous but with different supplemental inclusion levels of onion and garlic. A complete randomi

10. Antigenotoxicity and antimutagenicity of ethanolic extracts of Brazilian green propolis and its main botanical source determined by the Allium cepa test system
Abstract Brazilian green propolis is a resinous substance prepared by bees from parts of the plant Baccharis dracunculifolia. As it possess several biological properties, this work assessed the cytotoxic/anticytotoxic, genotoxic/antigenotoxic and mutagenic/antimutagenic potential of ethanolic extracts of Brazilian green propolis (EEGP) and of B. dracunculifo

11. Salt stress: antioxidant activity as a physiological adaptation of onion cultivars
The germination and development of several plant species can be limited when those plants are grown in soils with high salinity, which reduces seedling viability and vigor, as well as activating the antioxidant defense system. The aim of this study was to evaluate germination, initial growth and activity of antioxidant enzymes (superoxide dismutase, catalase

12. Desenvolvimentos mecânicos e computacionais de suporte às medidas com sensores termoelásticos
The hydrostatic pressure inside the cell or simply cell turgor is an important component of texture in vegetables and is directly related to firmness. The decrease in cell turgor of plant organs is also an indicator of loss of tissue water. This effect can be perceived visually by wilting accompanied by a dry appearance with the loss of brightness and color
