    Shimizu, Milton Massao; Mazzafera, Paulo (Instituto de Tecnologia do Paraná - Tecpar, 2000-07)
    Endosperm is the main reserve tissue in coffee seeds. Coffee (Coffea arabica L.) seeds were germinated for six weeks and qualitative and quantitative changes in amino acids and proteins were investigated. The total content ...
  • Genetic diversity among forty coffee varieties assessed by rapd markers associated with restriction digestion
    Diniz, Leandro Eugênio Cardamoni; Ruas, Claudete de Fátima; Carvalho, Valdemar de Paula; Torres, Fabrício Medeiros; Ruas, Eduardo Augusto; Santos, Melissa de Oliveira; Sera, Tumoru; Ruas, Paulo Maurício (Instituto de Tecnologia do Paraná - Tecpar, 2005-07)
    The genetic variability of 40 accessions of C. arabica was evaluated using a combination of the random amplified polymorphic DNA (RAPD) technique and restriction digestion of genomic DNA. The genetic variability and the ...
  • Influence of coffee pruning on the severity of frost damage
    Androcioli Filho, Armando; Caramori, Paulo Henrique (Instituto de Tecnologia do Paraná - Tecpar, 2000-03)
    Frost damages in a field experiment of pruning types and systems for the cultivars of Coffea arabica Catuaí and Mundo Novo, were evaluated at Londrina (23 o 22’S, 52 o 10 ́W), State of Parana, southern Brazil, during the ...
  • Partial resistance to fruit necrosis associated to Colletotrichum spp. among arabic coffee genotypes
    Sera, Gustavo Hiroshi; Sera, Tumoru; Ito, Dhalton Shiguer; Azevedo, José Alves de; Ribeiro Filho, Claudionor; Mata, João Siqueira da (Instituto de Tecnologia do Paraná - Tecpar, 2007-05)
    The aim of this study was to evaluate the resistance to fruit necrosis associated to Colletotrichum spp. in Coffea arabica L.. Twenty-two arabic coffee genotypes were performed in a randomized block design, with three ...
  • Production, composition, fatty acids profile and stability of milk and blood composition of dairy cows fed high polyunsaturated fatty acids diets and sticky coffee hull
    Santos, Geraldo Tadeu dos; Schogor, Ana Luiza Bachmann; Romero, Jakeline Vieira; Lima, Luciano Soares de; Pintro, Paula Toshimi Matumoto-; Grande, Paula Adriana; Kazama, Daniele Cristina da Silva; Santos, Fabio Seiji dos (Instituto de Tecnologia do Paraná - Tecpar, 2014-07)
    Four lactating Holstein cows were assigned to a 4 × 4 Latin square design to determine the effects of feeding sticky coffee hull (SCH) as a source of antioxidants on dairy cows fed with high PUFA diets. The treatments (on ...
  • Tolerance of arabica coffee cultivars for aluminum in nutritive solution
    Macedo, Célia Maria Peixoto de; Lopes, José Carlos; Amaral, José Augusto Teixeira do; Fonseca, Aymbiré Francisco Almeida da; Amaral, José Francisco Teixeira do (Instituto de Tecnologia do Paraná - Tecpar, 2011-09)
    This work aimed to evaluate the Coffea arabica cultivars for aluminum toxicity tolerance, in modified Hoagland solution. A completely randomized design with five repetitions in a factorial 4 x 4 (cultivar x combinations ...
