ABSTRACT. In contrast to climacteric fruits, in which ethylene is known to be pivotal, the regulation of ripening in non-climacteric fruits is not well understood. The strawberry is a typical example of a non-climacteric fruit, which has been used as a model system of these types of fruit. In this study, the effect of exogenous ethephon on the expression of ethylene biosynthesis and signaling genes, FaERF2 and FaACO1, was analyzed in the Fragaria ananassa cultivar Camino Real by quantitative real-time polymerase chain reaction, and the physicochemical and phytochemical characteristics of fruits were evaluated in field trials and postharvest tests. Transcript accumulation was influenced by exogenous treatment with ethephon, which affected the pattern of gene expression during different stages of growth and fruit development, with the highest expression occurring during postharvest tests. In addition, ethephon significantly influenced the phytochemical profile of sugars, anthocyanins, phenolic compounds, and vitamin C contents both in the field-and postharvesttreated fruits at different stages. These results indicate that ethylene regulates the phenylpropanoid maturation pathway in strawberry fruit.
ResumoA implantação de um programa de gerenciamento de resíduos é algo que exige, antes de tudo, mudanças de atitudes, e por isso, é uma atividade que traz resultados a médio e longo prazo, além de requerer reeducação e uma persistência contínua. O objetivo do projeto é a implantação do programa de gerenciamento de resíduos químicos nos laboratórios de Química da UTFPR-PG, através de procedimentos adequados para a segregação e descarte final dos resíduos químicos gerados nos respectivos laboratórios. Palavras-chave: projeto, programa, gerenciamento, segregação.
