  • Sartor, Rosana Mary; Mazzafera, Paulo (Instituto de Tecnologia do Paraná - Tecpar, 2000-01)
    The low caffeine content in leaves of C. dewevrei (~ 0.5 mg/g) is due to a low biosynthesis associated with a fast degradation. On the other hand, high biosynthesis and low degradation confer a higher content (~ 8 mg/g) ...
  • Caramori, Lázara Pereira Campos; Caramori, Paulo Henrique; Manetti Filho, João (Instituto de Tecnologia do Paraná - Tecpar, 2002-12)
    Young coffee plants from cultivar Mundo Novo of Coffea arabica were grown without irrigation for 32 consecutive days, to evaluate the effect of leaf water potential on damage caused by low temperatures, under controlled ...
