Physiological changes of Arabica coffee under different intensities and duratio...
Silva, Patrícia Carvalho da; Ribeiro Junior, Walter Quadros; Ramos, Maria Lucrecia Gerosa; Rocha, Omar Cruz; Veiga, Adriano DellyCoffee farmers have faced problems due to drought periods, with irrigation being necessary. In this sense, this study aimed to evaluate the responses to different levels and durations of water deficit in arabica coffee genotypes in the Cerrado region. The experiment consisted of three Coffea arabica genotypes and five water regimes: full irrigation (FI 100 and FI 50—full irrigation with 100% and 50% replacement...
Agronomic performance and adaptability of arabic coffee resistant. To leaf rust...
Veiga, Adriano Delly; Rocha, Omar Cruz; Guerra, Antônio Fernando; Bartholo, Gabriel Ferreira; Rodrigues, Gustavo Costa; Pereira, WelingtonBreeding programs and later indication of rust resistant cultivars for different environments and crops systems, in the concept of diseases integrated control, reach out for productivity raising and reduced production costs. The aim of this work was to evaluate the agronomic performance and adaptability of new Coffea arabica cultivars and progenies resistant to leaf rust in Central Brazilian Savanna. The experi...
Pre-imbibition: Effects in the germination, seedling growth and content of caff...
Rosa, Sttela Dellyzete Veiga Franco da; Mazzafera, Paulo; Guimarães, Renato Mendes; Veiga, André Delly; Veiga, Adriano DellyCoffee seeds (Coffea arabica L.) contains from 1% to 2% of caffeine, a highly water-soluble alkaloid, which inhibits germination of several species. This work was undertaken to evaluate the effects of treatments of pre-imbibition and running water washing on physiological performance and caffeine content of coffee seeds, with the following treatments: pre-imbibition in water under stirring for 6, 12 and 24 hour...
