(Associação Brasileira de Tecnologia de Sementes - ABRATES, 2019)The digital image analysis of seedlings has become largely employed in seed quality-control programs due to its feasibility, objectivity and fast results. Despite these advantages, no studies have yet demonstrated the ... -
(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 ...
-
(Associação Brasileira de Tecnologia de Sementes - ABRATES, 2019)Radiographic analysis has been efficient in identifying the main changes in the internal morphology of seeds, being increasingly used in quality control programs due to their practicality, objectivity and speed in obtaining ...
-
(Associação Brasileira de Tecnologia de Sementes - ABRATES, 2021)The physiological priming has been used to standardize and increase the speed of development of seed lots. The use of this technique is essential in coffee cultivation, as the crop has low longevity associated with slow ...
-
(Associação Brasileira de Tecnologia de Sementes - ABRATES, 2021)Seed deterioration induces the formation of free radicals and proliferation of microorganisms, but the application of external antioxidants may lessen these effects. The aim of this study was to investigate the antioxidant ...
-
(Associação Brasileira de Tecnologia de Sementes - ABRATES, 2021)Maintaining the health of coffee seeds is especially important during storage, as soil fungi and storage fungi can considerably reduce seed quality. Thus, chemical treatments for protection of seeds in storage becomes ...
-
(Sociedade Brasileira de Genética, 2000)The coffee germplasm bank of the Instituto Agronômico de Campinas has many Coffea arabica accessions from Ethiopia, which is considered the primary center of genetic diversity in coffee plants. An evaluation of the caffeine ...
-
(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 ...
-
(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 ...
-
Assessment of genetic variability within and among coffee progenies and cultivars using RAPD markers(Sociedade Brasileira de Genética, 2003)The RAPD technique associated with restriction digestion of genomic DNA was used to assess the genetic variability within and among nine populations of Coffea arabica, including six progenies belonging to the Sarchimor ...
-
(Sociedade Brasileira de Genética, 2003)Caffeine and used coffee grounds completely blocked the development of Aedes aegypti in the early stages, in treatments with the concentrations 1.0 mg/mL and 50 mg/mL, respectively. More advanced stages and even adults ...
-
(Sociedade Brasileira de Genética, 2008)Caffeine inheritance was investigated in F2 and BC1F1 generations between Coffea arabica var. Bourbon Vermelho (BV) and Coffea canephora var. Robusta 4x (R4x). The caffeine content of seeds and leaves was determined during ...
-
(Sociedade Brasileira de Genética, 2009)In this work, we studied the biosynthesis of caffeine by examining the expression of genes involved in this biosynthetic pathway in coffee fruits containing normal or low levels of this substance. The amplification of ...
-
(Sociedade Brasileira de Genética, 2010)Microsatellite markers, also known as SSRs (Simple Sequence Repeats), have proved to be excellent tools for identifying variety and determining genetic relationships. A set of 127 SSR markers was used to analyze genetic ...
-
(Sociedade Brasileira de Genética, 2010)Sequences potentially associated with coffee resistance to diseases were identified by in silico analyses using the database of the Brazilian Coffee Genome Project (BCGP). Keywords corresponding to plant resistance mechanisms ...
-
(Sociedade Brasileira de Genética, 2014)As microRNAs (miRNAs) are important regulators of many biological processes, a series of small RNAomes from plants have been produced in the last decade. However, miRNA data from several groups of plants are still lacking, ...
-
(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 ...
-
(Sociedade Brasileira de Genética, 2017)Nitrogen (N) is quantitatively the main nutrient required by coffee plants, with acquisition mainly by the roots and mostly exported to coffee beans. Nitrate (NO3 –) and ammonium (NH4 +) are the most important inorganic ...
-
(Sociedade Brasileira de Genética, 2018)Coffee is one of the most valuable agricultural commodities and the plants’ leaves are the primary site of infection for most coffee diseases, such as the devastating coffee leaf rust. Therefore, the use of bacterial ...
-
(Universidade Federal de Viçosa, 2019)O estudo realiza uma análise histórico-comparada da evolução institucional das dimensões tecnológica, comercial e organizacional do Sistema Agroindustrial (SAG) do café na Colômbia. Para esse fim, foram estabelecidas as ...
