Evaluation of the potential of agro-industrial waste-based composts to control ...
Santos, Cátia; Monte, Joana; Vilaça, Natália; Fonseca, João; Trindade, Henrique; Cortez, Isabel; Goufo, PiebiepComposts are widely used in horticulture as organic amendments to improve the properties of soils. Composts have also been reported to enhance the disease suppressive potential of soils and, therefore, could be used as a strategy for managing plant diseases. The aim of this study was to test the ability of soils amended with four different agro-industrial waste-based composts (chestnut peels and shells, spent c...
Chitosan upregulates the genes of the ROS pathway and enhances the antioxidant ...
Singh, Rupesh Kumar; Soares, Bruno; Goufo, Piebiep; Oliveira, Ana Alexandra; Inês, António; Cosme, Fernanda; Castro, Isaura; Falco, VirgilioChitosan is an environmentally-friendly active molecule that has been explored for numerous agricultural uses. Its use in crop protection is well-known, however, other properties, such as bioactivity, deserve attention. Moreover, the modes of actions of chitosan remain to be elucidated. The present study assessed the levels of total phenolic compounds, the antioxidant potential, and the expression of reactive o...
Effect of lignocellulosic and phenolic compounds on ammonia, nitric oxide and g...
Santos, Cátia; Goufo, Piebiep; Fonseca, João; Pereira, José L.S.; Ferreira, Luis; Coutinho, João; Trindade, HenriqueComposting is recognised a promising technology for recycling and adding value to agro-food wastes. There are, however, potential environmental risks associated with composting, such as the emission of greenhouse gases (GHGs). The aim of this study was to quantify the emissions of carbon dioxide, methane, nitrous oxide, nitric oxide and ammonia during composting of five agro-food wastes originated from the broc...

Appropriate set of pre- and post-harvest treatments for obtaining high levels o...
Goufo, PiebiepAromatic rices (Oryza sativa L.) constitute a special group of rice accessions well known for their aroma and/or superfine grain quality. For a successful development of aromatic rices, research regarding factors affecting the quality of the aroma is of economic interest to rice growers and processors. Therefore, this study was conducted as a preliminary step towards the rice quality improvement of two aromatic...
