RESUMOOs frutos da umbu-cajazeira (Spondias sp.) são amplamente consumidos frescos ou processados, em decorrência de suas características sensoriais, apresentando-se com boas perspectivas de cultivo e comercialização. No entanto, a avaliação da qualidade pós-colheita de frutos de acessos das suas áreas de ocorrência se faz necessária, no sentido não apenas de identificar materiais com características promissoras de interesse para a indústria ou consumo fresco, mas também para dar suporte aos programas de melhoramento. Neste trabalho foram avaliados frutos colhidos na maturidade comercial (coloração totalmente amarela) de oito acessos provenientes do município de Areia, Brejo paraibano, quanto às características físicas e físico-químicas. A massa fresca média dos frutos dos acessos avaliados foi de 28,82 g e o rendimento médio em polpa foi de 68,5%. Com base na análise de componentes principais, o acesso A2 se destacou por apresentar conteúdos superiores de sólidos solúveis (12,9%) e açúcares redutores (10,9%), mais baixa acidez titulável (0,94% de ácido cítrico) e superior relação SS/AT (13,75), indicando que este acesso pode ser uma alternativa viável, tanto para o mercado de frutas frescas como para o processamento.

However, postharvest quality evaluation of fruits of access occurring in areas is needed seeking to identify material of interest for the industry or fresh consumption, as well as to provide support for breeding programs. In this study quality of fruits harvested at the commercial maturity of eight access, from municipality of Areia in 'Brejo paraibano' was evaluated, as for the physical and physicochemical characteristics. The mean fresh mass for fruits from all evaluated access was 28.82 g and the pulp yield was 68.5%. Based on principal component analysis, the A2 access was highlighted by presenting higher contents of soluble solids (12.9%) and reducing sugars (10.9%), lower titratable acidity (0.94% of citric acid), and higher SS/TA ratio (13.75), indicating that access can be a reliable alternative for fresh fruit market and processing.

The weed Senna obtusifolia causes severe damages to pasture areas in Brazil, due to its high production and seed spread. This study aimed to evaluate the bioherbicidal action of Phoma dimorpha fermented broth in the pre-emergence and post-emergence of S. obtusifolia. The experimental design was completely randomized, with two treatments, one with and other without the application of the fermented broth. The bioherbicidal effects were measured in bioassays of pre-emergence (germination percentage), detached leaves (phytotoxicity) and post-emergence (phytotoxicity, plant height and fresh plant mass). The application of the fermented broth provided a pre-emergence bioherbicidal action, inhibiting the seed germination in 100 %. In detached leaves, it caused leaf necrosis and death on the ninth day after the application. In the post-emergence, this application caused moderate symptoms, such as leaf spots and reduction in the weed plant size. It was concluded that the P. dimorpha fermented broth has a potential herbicidal action and, therefore, represents an alternative in the development of bioproducts for a sustainable weed control in pastures.

The objective of this work was to evaluate the physical and physicochemical characteristics of lemon ‘Galego’(Citrus aurantifolia Swingle) in different maturation stages, from family farms in Matinhas, PB, Brazil. For the physical evaluations were considered, the length and diameter of the fruit; fresh fruit mass and juice yield; already for the physical-chemical evaluations of the pulp of the fruits was submitted to the determinations of the pH; soluble solids (SS); titratable acidity (TA); soluble solids /titratable acidity ratio (SS/AT) and ascorbic acid. There was a significant difference between the maturation stages for the variables diameter, fresh mass and juice yield, titratable acidity and ascorbic acid. Lemon fruits presented increase in pulp diameter and yield, titratable acidity and ascorbic acid reduction. pH, soluble solids and SS/AT ratio did not vary with the advancement of maturation. Based on the aspects of quality evaluated, the lemon ‘Galego’from Matinhas, PB, Brazil presents satisfactory quality for the market.
