  • Drying of arabica coffee and its effect on the gene expression and activity of enzymes linked to seed physiological quality
    Carvalho, Mayara Holanda de; Rosa, Sttela Dellyzete Veiga Franco da; Coelho, Stefânia Viias Boas; Guimarães, Cristiane Carvalho; Martins, Rayana de Sá; Clemente, Aline da Consolação Sampaio; Paiva, Luciano Vilela (Editora da Universidade Estadual de Maringá - EDUEM, 2023)
    The reduced longevity of coffee seeds has been attributed to their sensitivity to desiccation. Studies related to gene expression and enzyme activity in coffee seeds under drying are important for understanding the effects ...
  • Leaf area index and radiation extinction coefficient of a coffee canopy under variable drip irrigation levels
    Costa, Jéfferson de Oliveira; Coelho, Rubens Duarte; Barros, Timóteo Herculino da Silva; Fraga Junior, Eusímio Felisbino; Fernandes, André Luís Teixeira (Editora da Universidade Estadual de Maringá - EDUEM, 2019)
    The leaf area index (LAI) is relevant in studies of phenomena at different scales, such as for the leaf to canopy scale and the calculation of the extinction coefficient of photosynthetically active radiation (kPAR), ...
  • Microclimate in coffee plantation grown under grevillea trees shading
    Pezzopane, José Ricardo Macedo; Souza, Paulo Sérgio de; Rolim, Glauco de Souza; Gallo, Paulo Boller (Editora da Universidade Estadual de Maringá - EDUEM, 2011-04)
    Measurements of solar global radiation, wind speed, temperature and relative humidity of air were made in a coffee plantation (Coffea Arabica L. variety Icatu Vermelho- IAC 4045), grown under conditions of shading levels ...
  • Proposed diagrammatic scale to assess heat injury in coffee seedling canopy
    Resende, Laís Sousa; Pozza, Edson Ampélio; Pereira, Renata Cristina Martins; Botrel, Élberis Pereira; Roteli, Karolaine de Cássia; Oliveira, Júlia Marques (Editora da Universidade Estadual de Maringá - EDUEM, 2023-04-28)
    A diagrammatic scale with five levels (0, 0.1 - 2.0, 2.0 - 6.0, 6.0 - 10, and 10 - 14) was developed and evaluated to measure the symptoms of heat injury in a coffee seedling canopy. The scale was constructed to increase ...
  • Water use efficiency by coffee arabica after glyphosate application
    Carvalho, Felipe Paolinelli de; França, André Cabral; Souza, Bruna Pereira de; Fialho, Cíntia Maria Teixeira; Santos, José Barbosa dos; Silva, Antonio Alberto da (Editora da Universidade Estadual de Maringá - EDUEM, 2014-07)
    Many coffee growers apply glyphosate in directed applications, but some phytotoxicity has been noted. It is believed some herbicides can exert a direct or indirect negative effect on photosynthesis by reducing the metabolic ...
