-
(Sociedade Brasileira de Genética, 2015)Increased synthesis of galactinol and raffinose family oligosaccharides (RFOs) has been reported in vegetative tissues in response to a range of abiotic stresses. In this work, we evaluated the transcriptional profile of ... -
(Editora UFLA, 2015-03)Irrigation has enhanced coffee production in several regions of Brazil. However, with the increase in irrigated crop areas, problems related to the frequent and poorly planned usage of irrigation may arise. Since there are ...
-
(Associação Brasileira de Tecnologia de Sementes - ABRATES, 2019)Germination of the coffee (Coffea arabica L.) seed is the result of events that occur simultaneously in the embryo and endosperm. To understand the molecular mechanisms responsible for these events, we undertook a transcriptome ...
-
(Empresa Brasileira de Pesquisa Agropecuária - Embrapa, 2012-07)The objective of this work was to identify genes that could be used as suitable markers for molecular recognition of phenological stages during coffee (Coffea arabica) fruit development. Four cultivars were evaluated as ...
-
(Escola Superior de Agricultura "Luiz de Queiroz", 2007-09)The Citrus Variegated Chlorosis and the Coffee Leaf Scorch are some of the many destructive diseases caused by Xylella fastidiosa, a gram-negative bacterium limited to the xylem of affected plants. As its genetic ...
-
(Crop Breeding and Applied Biotechnology, 2020)Brazilian coffee cultivation was boosted over the last few decades by the mechanization of various field operations. Considering the influence of genetic factors on coffee harvesting efficiency, we aimed to evaluate the ...
-
(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 ...
-
(Editora UFLA, 2015-01)Potassium is a source of non-renewable natural resource, and is used in large quantities in coffee fertilization through basically imported formulations in the form of potassium chloride. An alternative to make production ...
-
(Escola Superior de Agricultura "Luiz de Queiroz", 2005-07)One of the greatest problems in Coffea arabica breeding is identifying precisely any inbred line, based only on botanical and agronomical descriptors, because of the reduced genetic variability of the species, close pedigree ...
-
(Academia Brasileira de Ciências, 2018)Knowledge of the genetic variability of a population is essential to guide its preservation and maintenance in addition to increasing the efficiency of genetic breeding programs. On this basis, this study was conducted to ...
-
(Sociedade Brasileira de Genética, 2003)Knowledge of the genetic variability among genotypes is important for the transfer of useful genes and to maximize the use of available germplasm resources. This study was carried out to assess the genetic variability of ...
-
(Editora UFLA, 2014-07)In order to investigate the aspects related to the use of selection indexes in Coffea arabica breeding, analytical procedures were used: index based on the sum of ranks of Mulamba and Mock (ISR), index of desired gains of ...
-
(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 ...
-
(Sociedade Brasileira de Genética, 2003)Inter-simple sequence repeat (ISSR) markers were used to evaluate genetic divergence among eight Coffea species and to identify the parentage of six interspecific hybrids. A total of 14 primers which contained different ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2005-01)The genetic variability for frost resistance was evaluated in field conditions and cold chamber among Coffea accessions. Results showed that C. liberica var. dewevrei and C. racemosa, as well as hybrids obtained from these ...
-
(Empresa Brasileira de Pesquisa Agropecuária - Embrapa, 2019)The objective of this work was to quantify the genetic variability of 213 conilon coffee accessions of the Robusta Tropical cultivar, based on Chemical characteristics related to the quality of green coffee beans, as well ...
-
(Universidade Federal de Lavras, 2022-06-09)This study aimed to analyze the genetic variability of Coffea canephora population with 190 genotypes from cultivar ‘ES8152’, based on morphoagronomic characteristics and vegetation index, to identify the most important ...
-
(Instituto Agronômico (IAC), 1949)The known species of Coffea can be grouped into two categories according to the color of their endosperm which is either green or yellow. The commercially cultivated varieties of Coffea arabica L. and Coffea canephora ...
-
(Instituto Agronômico (IAC), 1941-06)1. Foi feita uma revisão dos casos já descritos por Krug (4) de mutações somáticas do par de alelos Na-na do Coffea arabica L. 2. Foram descritos com detalhes três novos casos de mutações somáticas dêsse par de gens, a ...
-
(Instituto Agronômico (IAC), 1942)A variedade maragogipe do Coffea arabica L. foi encontrada pela primeira vez por Crisógono José Fernandes, em 1870, no município baiano de Maragogipe onde, provavelmente, se originou por mutação. Desde 1933 esta variedade ...
