(Editora UFLA, 2019-04)Growing Coffea arabica in regions of the Western Amazon is limited by early maturation and by its limited adaptation to regions of low altitude and high temperature. The aim in this study was to quantify the genotype × ... -
(Universidade Federal de Santa Maria, 2020)The development of Coffea canephora cultivars is based on the characterization of genotype × environment interaction, which is interpreted to quantify the differential behavior of clones at different cultivation sites. The ...
-
(Crop Breeding and Applied Biotechnology, 2020)Amazonian Robustas are ten new clones of high yield potential with characteristics typical of the botanical varieties conilon and robusta. With individual registration, the new cultivars were developed to be grown together ...
-
(Editora da Universidade Estadual de Maringá - EDUEM, 2021)This study aimed to evaluate the beverage quality of Coffea canephora genotypes in different environments of the western Amazon to assist plant selection and new cultivar development. To analyze beverage quality, samples ...
-
(Editora UFLA, 2020)Most of the Western Amazon coffee production is made from growing unregistered clones, selected by the coffee growers themselves. The aim of this study is to evaluate the sensory profile and genetic diversity of the most ...
-
Coffea canephora breeding: estimated and achieved gains from selection in the Western Amazon, Brazil(Universidade Federal de Santa Maria, 2021)Gain from selection is an important criterion in quantifying the efficiency of breeding programs. This study quantified the selection gain estimated under experimental conditions and realized gain achieved in the field, ...
-
(Editora UFLA, 2017-07)O ciclo de maturação dos frutos do cafeeiro Coffea canephora é uma característica de herança complexa, de expressão governada por vários genes influenciados pelo ambiente, o que resulta em uma característica quantitativa ...
-
(Editora da Universidade Estadual de Maringá - EDUEM, 2019)Knowledge on the dynamics of micronutrients in coffee tree assists nutritional diagnosis and fertilization management. Therefore, the objective of this study was to evaluate the concentration and accumulation of micronutrients ...
-
(Editora UFLA, 2018-01)The aim in the present study was to evaluate the growth of Coffea canephora cv. ‘Conilon BRS Ouro Preto’ seedlings in different tube volumes. The experiment was performed at Embrapa Rondônia plant nursery in Ouro Preto do ...
-
Dry matter and macronutrient accumulation in fruits of conilon coffee with different ripening cycles(Sociedade Brasileira de Ciência do Solo, 2014-01)The period between anthesis and fruit ripening varies according to the Conilon coffee (Coffea canephora) genotype. Therefore, the time of the nutritional requirements for fruit formation may differ, depending on the formation ...
-
(Universidade Federal de Viçosa, 2020)In Coffea canephora, the number of orthotropic shoots is directly related to plant yield. The objective of this study was to evaluate the vegetative and yield performance of Coffea canephora, from the botanical variety ...
-
(Editora UFLA, 2021)Change in the performance of clones grown in different environments is an important question for Coffea canephora breeding. The aim of this study was to evaluate environmental stratification and the performance of C. ...
-
(Empresa Brasileira de Pesquisa Agropecuária - Embrapa, 2022-12-05)The objective of this work was to characterize the expression of gametophytic self-incompatibility in a Coffea canephora breeding population, to assist in the management and development of new cultivars. For that purpose, ...
-
(Universidade Federal de Santa Maria, 2018-03)The aim of this study was to select Coffea canephora clones of superior processed coffee productivity based on the estimates of the genetic parameters and of genetic progress with the plant selection. For this, the production ...
-
(Universidade Federal do Ceará, 2020)The intrinsic characteristics of the vegetative propagule may influence the rooting speed and shoot growth, as well as the final physiological quality of clonal seedlings of Coffea canephora. The aim of this study was to ...
-
(Editora UFLA, 2017-04)O conhecimento do padrão de crescimento do cafeeiro torna-se fundamental para auxiliar no manejo da lavoura, em virtude da ocorrência de sazonalidade de crescimento ao longo do ano. Objetivou-se avaliar o crescimento ...
-
(Editora UFLA, 2019-10)The objective in this work was to study the influence of the North-South plantation alignment with respect to microclimatic, growth, and mineral nutrition conditions in order to quantify the variables and to point out ...
-
(Sociedade Brasileira de Ciência do Solo, 2015-09)The number of days between anthesis and maturation of conilon coffee berries varies according to the genotype. Thus, it is believed that periods of greater nutrient demand for fruit formation also vary according to the ...
-
(Empresa Brasileira de Pesquisa Agropecuária - Embrapa, 2022-09-12)The objective of this work was to evaluate the production of cuttings of Coffea canephora genotypes, in a new system for training mother plants called “vertical clonal garden”. The proposed new system consists of training ...
-
(Editora UFLA, 2016-10)As tecnologias de cultivo do Coffea canephora avançaram significativamente, bem como as exigências nutricionais das plantas. Objetivou-se estabelecer faixa de suficiência e normas DRIS, para lavouras de cafeeiro Conilon ...
