(Instituto de Tecnologia do Paraná - Tecpar, 2013-01)The objective of the study was to evaluate the resistance to rust in coffee cultivars developed by research institutes of Brazil in Paraná state. Resistance to the local leaf rust races was assessed in high disease intensity ... -
(Instituto de Tecnologia do Paraná - Tecpar, 2013-11)Two analytical methods for the determination and confirmation of ochratoxin A (OTA) in green and roasted coffee samples were compared. Sample extraction and clean-up were based on liquid–liquid phase extraction and ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2006-01)Transgenic plants of Coffea canephora P. resistant to the herbicide ammonium glufosinate were regenerated from leaf explants after co-culture with Agrobacterium tumefaciens strain EHA105 harboring pCambia3301, a plasmid ...
-
(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 ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2013-09)The objective of this study was to evaluate the influence of integral and decaffeinated coffee brews (Coffea arabica L and C. canephora Pierre) on the metabolic parameters of rats fed with hyperlipidemic diet. Thirty male ...
-
(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 ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2004-11)Modifications on leaf anatomy in Coffea arabica shaded with pigeonpea (Cajanus cajan), compared to cultivation under full sun, were assessed. The leaves fully exposed to sunlight presented thicker cuticles and cellular ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2004-08)The objective of this study was to analyze the effect of biosolid composts (BC) and carbonized rice hull (RH) on the production of Coffea arabica L. cv Catuaí Vermelho seedlings (IAC H 2077-2-5-99) grown in tubets. A totally ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2003-03)Dietary protein and energy utilisation of diets containing fresh and ensiled coffee pulp were studied on 3.2 ± 0.2 g Nile tilapia for 28 days. Diets formulation and feeding were designed on the basis of daily dietary protein ...
-
(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 ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2001-06)Solid state cultivation (SSC) was carried out to evaluate the feasibility of using coffee husk and spent-ground as substrates for the production of edible mushroom Flammulina under different conditions of moisture and spawn ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2011-01)A field experiment was conducted for ten years in a sandy soil in the north part of the Paraná State, Brazil. The soil samples were collected at 0-10 cm depth, both under the coffee canopy and in the inter row space between ...
-
Partial resistance to fruit necrosis associated to Colletotrichum spp. among arabic coffee genotypes(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 ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2007-03)An indirect competitive enzyme-linked immunosorbent assay (ic-ELISA) for ochratoxin A (OTA) detection in green, roasted and instant coffees was developed using anti-OTA monoclonal antibody. Immunological reagents prepared ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2004-03)This study aimed the identification of cultivars and/or lines of Coffea arabica of commercial interest, using PCR-RAPD markers. The DNA of ground seeds lots of 12 cultivars and/or lines were evaluated with five primers ...
-
(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) ...
